Due to the urbanization, concentrated population, and limited land exploitation in the modern society, the environment surrounding that we live in is getting polluted more and more, and it has become hard even to let urban children experience the nature. This research was conducted to help people recognize the importance of our natural resources through the environmental education of elementary school and to use school's practical open-space for the Indigenous Plants education. The results of this study are as follows : First, the status of a plant utilization in our institutional education : There were 362 species totally of 124 species of Trees, 156 species of Herbs, 63 species of Crops, and 19 species of Hydrophytes which appear in the elementary school text book. Of all, the most frequently appearing species of tree were the Malus pumila var. dulcissima, Pinus densijlora, Citrus unshiu, Diospyros kaki. Second, the effect of plant education using the land around schools : The result of research on the open-space of the 19 elementary schools located in Mapo-gu showed that most of the species planted are the Juniperus chinensisrose, Hibiscus syriacus. Pelargonium inquinans in the order of size, and the plants appearing in text book were grown in the botanical garden organized in 7 schools. Especially most of the Indigenous Plants were being planted in botanical garden, and Pinus densijlora, Abeliophyllum distichum, Polygonatum var. plurijlorum, Liriope platyphylla and so on. Last, the result of this research on recognition of Environment, Planting education and Indigenous plants : It showed that educational necessity of students and teachers about environment and Indigenous Plants was more than 80%. The management of botanical garden was conducted by some teachers and managers. The results of this study suggested that we needed the reconstruction of curriculum, the efficient application of plant education for effectiveness of using school environment and monitoring continually and construction information sources for the better environment education in the elementary schools.

This Study is about the "Comprehensive Landscape Improvement Plan for Gu-ryoung Seaside Village that was one of most exhibited projects for developing sea villages." The formulations of the plan were supervised by the Ministry of Land, Transport, and Maritime Affairs and were executed by the Goheung Country. Rather than proposing renovations for the landscape, this study maintains the existing order and attempts to examine the plan by scrutinizing the vernacular design language of the landscape. In the study, community members had the opportunity to express their opinions and ideas about the community through workshops composed of community participation programs, and participated in the decision-making process through consultation meetings. The conclusion of this study was relevant to the activities of the committee on landscape improvement. The Comprehensive Landscape Improvement Plan has three objectives: (1) resorting and modifying the natural landscape, (2) restructuring the roadways, and (3) modifying key spaces. In the end, the role of Gu-ryong Mountain as a background of the landscape was focused on tree planting drives that were undertaken, and accessibility to the sea front was improved. Second, in restructuring the roadways, rough roads were restored and unconnected roads were connected to ensure a network of roads along the sea front, inner roads in the village, roads at the Fringes Mountains, and stone roads on the mud flat. In addition, roads were named according to the character of the landscape and signs were installed. Finally, the existing key spaces, in which community members came together, were restored and new key spaces were created for the outdoor activities of the inhabitants and the diverse experience of visitors. A guideline was also created to regulate private areas such as roofs, walls, fences of residential buildings, and private container boxes and fishing gear along the sea front. The strength of this study is that it is seeking to determine the greatest potential of the landscape and set the plan by examining the lives of community members. Some problems were found during the development of this study. Further, there were problems in the community's understanding as elaborated below. First is the gap between community members' awareness and practice. Even though they were aware of the problems with the village landscape, they hesitated to implement improvements. Second, community members have misunderstandings about the landscape the improvement plan. The local government and the residents have understood this plan as a development project; for example, new building construction or the extension of roads. Third, residents are not aware that continuous attention and improvements are required for the upkeep of the landscape in the sea village. The plan to improve the landscape should promote a balance between making the area as a tourist attraction and maintaining the lives and cultural activities, because the sea village system incorporates settlements, economy, and culture.

The purpose of this study is to examine the roles of the forest-land registry system in the Forest Law of 1908 and the effects this system had on the colonial forest-land policy used in Korea under the influence of Japanese Imperialism. This was started under the Profit-sharing Forest System which was one of the policies for disposing of the Korean national forests. The purpose of this system was to establish forest-land ownership, a fundamental human right. This system was enforced by the Japanese Colonial Government without regard to the customary and important right of Koreans to use the forests, and without considering the distinction between national and private forests. Koreans understood that this system was a warning sign of a tax being imposing on forest-land owners. Furthermore, Koreans thought the Japanese were using this system to deprive them of their forest-land. The strata of Koreans reporting ownership were very limited and included the intellectual(upper-middle) class, higher officials in counties and townships, relatives and relations of these officials, and survey agents. In particular the actual owners could not submit a report registering their land in this system because the required survey cost more than the value of the forest-land. Within the time period specified by the Japanese Colonial Government, about 520,000 registries were reported involving 2.2 million Jung-bo(.9917 hectare) with most of these coming during the last five months of reporting period. Koreans made a reasonable request to extend the deadline, but it was refused. After the reporting period expired there were no follow-up measures such as verification of the reported registrations nor establishment of boundaries between national and private forests. According to Article 19 in the Forest Law of 1908 about 14 million Jung-bo, which was not registered within the reporting period was nationalized. The colonial forest-land policy used in Korea by the Japanese Colonial Government was as follows : (1) to create a large number of national forests in the early period of their rule, (2) to divide these national forests into indispensible national forests and dispensible national forests, and (3) to transfer ownership of the dispensible national forests to colonial Japanese. To achieve the latter, the occupational government needed a method to insure ownership. They devised a tree-planting scheme in which the national forests classified as disposable were "loaned" and then transferred to these Japanese. The actual Korean owners claimed title to this forest-land and asked for the eviction of the new owners but the Japanese occupation government rejected these suits using the excuse that previous Korean owners did not submit the required registration report within the specified time period. In short the Principle of Forest-land Registry was used as a means to consolidate the forest-lands of Korea and distribute large portions of it to Japanese citizens after seizing it from the rightful Korean owners.

Trial and demonslative reforestations were planted by Korea German Management Project at Ulju district in 1976. The follow results that were investigated at spring time in 1977 showed the different situation of winter damage according to site condition and species. 1. Picea abies was completely dried out in this district and its reason was to be thought as a winter damage by cold-dry wind. 2. Cryptomeria japonica was seriously damaged in comparing with Chamaecyparis obtusa and very seriously damaged on the wind-exposured site. So these species are also unsuitable species like Picea abies in this district. 3. The resistance ranking to winter dry wind damage were Picea, Cryptomeria, Chamaecyparis, ${\times}$ Pinus rigitaeda. Pinus rigida, Larix leptolepis and Alnus hirsuta. The falling leave species like larch in this district during winter were thought in necessary to select as the planting species for almost very little winter damage. 4. ${\times}$ Pinus rigitaeda to be showed as a suitable species in this district were also seriously damaged on exposured site and, Pinus rigida and Larix were also attacked with small damage. The potassium-phosphorus fertilizer dressing plots had a trend to reduce this winter damage until some level. 5. The winter climate can be devided into 10 zone in order to evaluate the right or wrong of suitable on the exotic species. The Yongnam region in eastern side of Sobaik mountain are far drier than the Honam region in western side of Sobaik mountain during winter time. Picea abies, Cryptomeria and Chamaecyparis originated in the high humidity winter climate are to be thought to be more suitable in the Honam region than the Yongnam region. Specially the suitable site of Picea abies should be only found in the region with high humidity and much precipitation except the Yongnam region.

This study was carried out to apply basic data of the native trees for planting in the salinity area by the vegetation ecological selection. Which focused on native woody species to the tolerances of saline soil and salt spray drift on the coastal forests in the West-Sea, Korea. The soil salinity($EC_{1:5}$) was 0.11dS$m^{-1}$, ranging of 0.00dS$m^{-1}$~0.68dS$m^{-1}$. The soil salinity was gradually decreasing from Belt I to Belt Ⅳ except the Belt I in some coastal windbreaks. The order of decreasing soil salinity was Belt I>Belt II>Belt III>Belt Ⅳ and the soil salinity was $EC_{1:5}$ 0.14dS$m^{-1}$, 0.11dS$m^{-1}$, 0.10dS$m^{-1}$, and 0.08dS$m^{-1}$, respectively. The total 181 taxa consisted of 52 families, 104 genus, 157 species, and 24 varieties were recorded as the trees tolerating to both soil salinity and salt spray drift. The trees emerged in the highest degree of salinity($EC_{1:5}$ 0.51dS$m^{-1}$) was nothing but appearanced Pinus thunbergii Parl., Smilax china L., Quercus dentata Thunb. ex Murray, Quercus serrata Thunb. ex Murray and so on at the level of singular and ideal value. The emerged trees in the high salinity of $EC_{1:5}$0.41dS$m^{-1}$~0.50dS$m^{-1}$ were Albizia kalkora Prain, Melia azedarach L., Paederia scandens (Lour.) Merr. var. scandens These species were trees of tolerance to saline soil. The emerged woody species in all belts were Pinus rigida Mill., Pinus densiflora Siebold & Zucc., Pinus thunbergii Parl., Juniperus rigida Siebold & Zucc. and so on. The woody species with high important value(I.V.) were Pinus densiflora Siebold & Zucc., Pinus thunbergii Parl., Pseudosasa japonica (Siebold & Zucc. ex Steud.) Makino, Smilax china L., Platycarya strobilacea Siebold & Zucc. var. strobilacea for. strobilacea and so on, which can be classified as highly tolerant native trees to salt spray drift.

This study was carried out to estimate the effect of NPK fertilization on tree seedling growth and chemical properties of soil. Seedlings of Betula platyphylla var. japonica and Fraxinus rhynchophylla were planted in May 1998 in the nursery at Gariwang mountain, Kangwondo, and seven NPK fertilizer plots(4, 12, 28, 60, 124, 252, and $508g/m^2$) and one non-fertilized plot were used to meet the study objectives. Seedlings of Pinus koraiensis and Acer mono were planted in April 1998 in plastic pots of nursery at Chungnam National University, and seven NPK fertilizer plots(0.5, 1.5, 3.5, 7.5, 15.5, 33.5 and 63.5g) and one non-fertilized plot were used to meet the study objectives. To estimate the relative growth ratios of the seedlings, height and root collar diameter of the seedlings were measured after planting and also in October 1998. Soil samples were collected in October 1998 from the nursery of Gariwang mountain and the plastic pot of the nursery of Chungnam National University. The relative growth ratios of height and root collar diameter in Betula platyphylla var. japonica, Fraxinus rhynchophylla and Acer mono were greater in all fertilized plot than non-fertilized plot, but there was no difference in relative growth ratio of height and root collar diameter of Pinus koraiensis between the fertilized and non-fertilized plots. NPK fertilization increased soil P and K, decreased exchangeable Ca and Mg, and base saturation, and pH. Fertilization resulted in no difference in total soil N between the fertilized and non-fertilized plots of nursery of Gariwang mountain, but increased in total soil N in plastic pots. Fertilization increased the growth of hardwood species and had changed soil chemical properties of this fertilizer trials.

This research was conducted to investigate the consciousness of demander on National Forest Management System and to seek for solution to activate it by measuring the variables such as the extent of goal achievement on the system, the extent of importance on function of national forest, benefit for participation of the system, and the extent of importance on the system as well as the extent of demander recognition and intention of participation on the system like, Cooperative Forest Program and People's Forest Program. The target of this investigation is to categorize consumers of National Forest Management System (NFMS) into four types such as environmental organization that do not participate in the system, environmental organization that participate in the team, company to publish a white paper on environmental and local government. As a result, the intention of participation was showed in C Type (62.7%), among fields that respondents interested in participation were tree planting and forest tending (56.2%). However, the rest of the participants were reluctant participate in the NFMS due to more benefit (72.2%) of corporate social responsibility from other fields than those from the field utilizing forestry. If only, diverse facilities related to national forest and active supporting policy are provided by Korea Forest Service, social participation using forest resources would be considered. Although 61% among A Type recognized NFMS in advance, the prime reason for not utilizing are the problems with reserving place for participates in and the inconvenience to participate in on-site. Type D shows slightly high interest in People's Forest Program (3.69). Also, it shows high interest in Forest Recreation (4.15) and Forest Reports (3.90). Particularly, it indicates that GyeongGi-Do and GangWon-Do local government prefers Forest Experience, and Cheolla, ChungCheong and GyeongSang local government prefer Forest Reports. Based on the above study, we finally suggest that legal alignment of the system, and the provision of incentive for inducement of voluntary participation by Corporate Social Responsibility (CSR), and establishment of new exclusive nongovernmental organization be able to operate the system as the solution to activate NFMS in terms of the consumer.

The objective of this study was to elucidate the tolerance of woody plants to simulated acid rain in relation to mycorrhizal inoculation. Germinating seedlings of Robinia pseudoacacia were planted in 1I pots with autoclaved soil mixture of vermiculite, sand and nursery soil at 1:1:1 ratio. Each pot was inoculated with both crushed root nodules from a wild tree of the same species and commercial arbuscular mycorrhizal inoculum of Glomus intraradices at the time of planting the seedlings. Simulated acid rains at pH 2.6, 3.6, 4.6, and 5.6 were made by mixing sulfuric acid and nitric acid at 3: 1 ratio. Each pot received nutrient solution without N and P, and was also supplied with 180 ml of the one pH level of the acid rains once a week for 50 days. The plants were grown in the green house. At the end of experimental period, plants were harvested to determine contents of chlorophyll, mineral nutrients and net photosynthesis in the tissues, dry weight of the plants, and mycorrhizal infection in the roots. Mycorrhizal infection rate was significantly reduced only at pH 2.6, which meant vitality of G intraradices was inhibited at extremely low pH. Height growth, dry weight production, nodule production and chlorophyll content were increased by mycorrhizal infection in all the pH levels except pH 3.6. Particularly, mycorrhizal inoculation increased root nodule production by 85% in pH 5.6 and 45% in 4.6 treatments. But the stimulatory effect of mycorrhizal inoculation on nodule production was reduced at pH 3.6 and 2.6. Net photosynthesis was increased by mycorrhizal infection in all the pH levels. The phosphorus(P) content in the tissues was increased by 43% in average by mycorrhizal inoculation, which was statistically significant except in pH 2.6. It was concluded that mycorrhizal inoculation of Robinia pseudoacacia would enhance growth and resistance of the plants to acid rain by improving the photosynthesis, phosphorus nutrition, and more nodule production.

In order to propose effective conservation management plan, this study verified ecological characteristics, humanities and Social characteristics. The research site is private property which is owned belonging to the Kim's of Gimhae that have long history. The study site is more than a thousand years old and was created for protecting from typhoon. There held the religious ritual what is called Dongsinje until 1960s. There have been protected and managed by the villagers. As the results of analysis, the area of windbreak are $12,392.69m^2$. The windbreak is dominated old years deciduous broad-leaved tree such as Zelkova serrata, Celtis sinensis, Aphananthe aspera. Around there were farmlands(52.1%), urbanized area(26.3%), forest area(16.6%). The vegetation communities of windbreak were classified by considering the dominant species and current status of forest. The forest types are following as; A. aspera community(I) which is using less pressure, Platycarya strobilacea-Carpinus coreana-Z. serrata community(II). Z. serrata community(III) which is using high pressure, Z. serrata-A. aspera community(IV), Z. serrata community(V) which is damaged under canopy trees. The windbreak was in good condition whereas, there were concerns the some wrong status was being undermined such as the wrong forest restoration projects in the past, the trails that is penetrating inside the forest, building up education facilities. Therefore, in order to restore the value of windbreak what is so called Suwol forest, we should improve the problems of forest ecosystem such as wrong management, forest fragmentation by facilities and decline in forest by lack of growing the next generation trees. In addition, we should remove excessive resting facilities and lead to passive use of forest. to improve the way of wrong management, moreover, we should close off he trails that is penetrating inside the forest for improving fragmentation. We should restore vegetation restoration and fostering the next generation trees for forest ecosystem. In order to restore unique of histo-cultural and ecological forest landscape, the next generation trees should be grown up that is the dominant species in Suwol forest. Moreover, as a results of comparing the between good vegetation communities and damaged vegetation communities, it is necessary to complementary planting for demeged vegetation communities, therefore there needs to 10.8 under canopy trees, 79.7 shrubs.

To widen prospect of villa as Korea traditional garden, the result of the research about constructional characteristics of Seogo-jeongsa and Sameun-jeong of Yeoju Lee family at Toero-ri, Miryang-si, Gyeongsangnam-do, Korea, is abstracted as below. Seogo-jeongsa(西皐精舍) and Sameun-jeong(三隱亭) was intended to practise retirement with sense of unity with the head residence, since Seogo-jeongsa was 340m far and sameun-jeong was 630m far away from head residence, which set within 1km. Although Seogo-jeongsa's basic prop, Sameun-jeong's timber, which are both from designer's pen name and head residence name, "Hangjae(恒齋)" and "Yongjae(庸齋)," and Hanseoam have each different exposure, it is homogeneous as space configurational side in order to optimize the gaze leading effect and appreciated domestic trees from the pond, which is center of the garden and the significant facility. Method of direction of Seogo-jeongsa's Hwalsudang(活水塘) and Sameunjeong's pond of Sameun-ji(三隱 池) gets attention by distinction. Especially, directing of 3 step water flow from behind to front and traditional pond method, called Bangji-Bangdo(方池方島), were very unique that any other place can be found. Also, the middle islet on the pond at both villa, which isn't more supper, but more for the symbolic molding that seek a stone pagoda(石假山), is more interesting directing method as considering the relationship of the 3 stone pagoda imageries on the surface of Ghwayukchon(果肉泉) At the same time, Seogo-jeongsa and Sameun-jeong shows very different characteristics from traditional villa that adopted both domestic trees and foreign trees. Particularly, it is extremely exceptional case to plant vigorous needleleaf tree, such as Chamaecyparis pisifera, C. obtusa, Pinus bungeana, P. palustris, Sciadopitys verticillata, Metasequoia glyptostroboides and Cedrus deodara, on Sameun-jeong. Moreover, adopting foreign wild needleleaf trees for landscaping trees, such as a Torreya nucifera, Taxus cuspidata, P. parviflora, and foreign landsacping trees, such as P. bungeana, Cryptomeria japonica and C. obtusa tells planting trend of the late Joseon dysnasty era. Also, as we can know from 2 Jipgyeong(集景), which is 'Seogo-jabyoung 17 young(西皐雜詠十七詠)', and 'Sameun-jeong 12 Gyoung(三隱亭十二景)' which are set on both villa, the intend to expand the garden area is strongly shown by the natural forest directing. As a result, Seogo-jeongsa and Sameun-jeong, located at Toero-li Miryang, are sharing the traditional Joseon dynasty era's custom, such as space and visual composition; however, it is different and attractive garden remains as a point of view of water directing, stone pagodas, and adopting foreign landscaping trees.
