The study was done to analyze the records of planting time of Gwangneung needle firs referring to the historical literatures, the Annals of Joseon Dynasty(朝鮮王朝實錄), Seungjeongwonilgi(承政院日記: Journal of the Royal Secretariat). Bibyeonsadeungnok(備邊司謄錄: Records of the Bibyeonsa Defense Council, a government agency during the Joseon Dynasty), Ilseongnok(日省錄: Journal on Dynasty affairs of the kings in the 36th year of Youngjo to 1910) to lay the historical ground for needle firs in Gwangneung. The following results were derived from previous research, Report on Gwangneung Forest Ecosystem, and overlaid fir tree rings. The research findings are as follow. First, since the system of making the grave is the most conservative system, the planting during the Gwangneung construction would have been preceded by precedent. Second, the problem of cutting the tree in the late Joseon Dynasty became serious. It is published the Law of Muo In the 22nd year of Jeongjo, and then planted trees regularly in spring and autumn. Third, the Law of Muo was preserved for 31 years during the reign of King Gojong, and the type of specific tree, the number of trees, from the 22nd year until the 25th year of King Gojong, four years of fir trees were planted in Gwangneung, and Gwangneung was the only place where korean pine trees were planted. Fourth, it was possible to identify the age of the tree through fallen fir tree rings, and the period of planting fir trees growing in the existing mausoleum is judged to be the equivalent year of King Gojong's reign from the 10th year of King Cheoljong's reign.

Background and objective: Plants in temples are the results of cultural symbolization that embraces the experience and enlightenment of humans about life. As a way to improve the acceptance of the foreign religion, China gave cultural symbolization to plants in temple gardens through integration with traditional cultures and the understanding of the nature of plants themselves. This study aimed to identify cultural symbolism and signs of acculturation associated with Buddhist plants, targeting Bolisu, the most essential and symbolic plant in temple garden forests in China and Korea. Methods: The morphological and ecological characteristics of plants, functions, the texts that contained the history of Buddhism and literary works were examined through literature review, and the relation of Ficus religiosa with its planting conditions and nature, and Buddhist culture was explored. In addition, the cultural value of Buddhist plants themselves in establishing temples and the reason why Bolisu was planted in temples were reviewed through time series analysis. The obtained results were interpreted using an inductive method to identify substitutes for F. religiosa, cultural symbolism and signs of acculturation. Results: F. religiosa as one of the three holy trees and the five trees and six flowers in Buddhism is known as the original Bolisu. Since it grows well and is widely distributed in regions that accepted Indian Buddhism, it became the most representative holy tree in Buddhism. From the perspective of tree shape and nature, F. religiosa is in line with the Buddhist spirit of saving those in need with mercy and redeeming mankind, and figuratively shows that perfection can be attained like the fruit of Bolisu. Chines Buddhism had adopted highly symbolic plants for a long period of time as a means to spread the same belief and doctrines as Indian Buddhism. In China, however, there were only limited areas suitable for the growth of F. religiosa, and for this reason, borrowed Bolisu trees including Tilia. miqueliana, T. mandshurica and T. amurensis and other plants such as F. virens Ait. var. sublanceolata, G. biloba and M. alba were planted as a substitute in most regions, having been given with symbolism and belief as Bolisu. Conclusion: Chinese Buddhism planted the same plants as Indian Buddhism in order to enhance symbolism and also similar substitutes to express the same symbolism. This is a kind of acculturation and its influence and customs were not limited to China, but were introduced to Korea, The difference between China and Korea was that G. biloba was excluded from the substitute for Bolisu in Korea.

Urban parks create the natural landscape of the city and offer a space for city residents to stay healthy and take a rest. They are also urban facilities designed to improve city dwellers' emotional aspects. Currently, urban parks need qualitative management as well as quantitative supply due to changes in the national land and urban policy paradigm, and a shift in perspective to consumer-centeredness is needed. In this study, the service levels of urban parks for citizen were evaluated: (1) quantitative supply adequacy was analyzed based on the urban population, and (2) the qualitative evaluation of the parks were conducted. Based on the evaluation, the appropriateness of the arrangement of urban parks is judged by comprehensively analyzing the quantitative and qualitative aspects. As a result of the evaluation of service levels of urban parks, the highest serviced urban parks were found in urban housing development sites and recently established parks. In addition, it was found that the recently created parks improved the qualities of the parks by installing various facilities. If the quantitative and qualitative aspects of urban park service supply are comprehensively analyzed and applied through this research method, it will be a more effective park and green space plan.

This study was carried out to offer the raw data on conservation of land and natural environment by constructing groups of indicators to objectively and rationally assess the sustainable natural ecosystem and present the direction for establishing and planning the environmental policy. There were selected that four assessment items were biotic, abiotic, qualitative, and functional factor. And there were extracted fifty-six indicators including density, total nitrogen, hemeroby degree, and goods production. As assessment items and indicators were over 0.6, the design of questionnaire showed no great problem. In the results of correlation analysis of assessment indicators, sociality and dominance was highly correlative in biotic factor, soil property and aspect in abiotic factor, naturalized and urbanized index in qualitative factor, and protection of landslide and soil erosion were too correlative. In the results of deciding the dimension by multidimensional scaling, as stress values were from 0.042 to 0.133, index of fit over 0.9, there no statistical problems. In case of X axis, biotic factor was structure, viewpoint in abiotic factor, composition in qualitative factor, and object in functional factor, and Y axis was shaped Into form, range, structure, and activity.

This study was conducted to investigate sensitivity of woody plants growing in urban and industrial regions of Seoul and Taejon, Korea. Malondialdehyde(MDA) contents were analyzed in tree foliage of Pinus densiflora, Pinus koraiensis, Ginkgo biloba, Liriodendron tulipifera and Platanus occidentalis. In addition, MDA contents were analyzed in the foliage of tree seedlings, i.e. Pinus densiflora. Pinus koraiensis, Ginkgo biloba and Liriodendron tulipifera, with the fumigation of $SO_2$ in gas chamber 4 hours a day for six days. MDA contents of leaves in Ginkgo biloba, Platanus occidentalis and Liriodendron tulipifera in polluted regions were higher than those in unpolluted region and among them Liriodendron tulipifera had the highest. MDA contents of Pinus densiflora and Pinus koraiensis increased with the increase of needle age. MDA contents of Liriodendron tulipifera seedlings were increased with the higher concentrations of $SO_2$ but MDA contents in other seedlings showed no changes with $SO_2$ treatment concentrations. MDA contents in all species were increased with the passage of exposure day. Especially. Liriodendron tulipifera had higher MDA content than other species. In Liriodendron tulipifera the MDA production increased with the passage of exposure day until the fourth day after that decreased.

The purpose of this study was to survey vegetation characteristics of Jeopdo (island) for the construction of a database. We installed and analyzed 52 plots with 100㎡ quadrat to investigate the vegetation characteristics. The community classification based on TWINSPAN found seven categories of vegetation communities in the surveyed region: Pinus thunbergii-Pinus densiflora community, Pinus densiflora-Quercus serrata community, Carpinus turczaninowii-Quercus variabilis community, Carpinus turczaninowii-Quercus acutissima community, Quercus variabilis-Carpinus turczaninowii community, Castanopsis sieboldii community, and Actinodaphne lancifolia-Camellia japonica community. The vegetation in Jeopdo is largely composed of evergreen conifer trees community (communities I and II), Carpinus turczaninowii-deciduous broad-leaved trees such as Quercus spp. community (communities III, IV, and V), and evergreen broad-leaved trees community (communities VI and VII). The evergreen conifer tree (Quercus serrata) community is currently competing with Pinus densiflora and Pinus thunbergii. The current state is expected to continue due to the lack of forces, such as Castanopsis sieboldii and Actinodaphne lancifolia, in the succession middle stage and climax stage. The current state of Carpinus turczaninowii-deciduous broad-leaved trees such as Quercus spp. community is expected to last for a long time due to slow vegetation development because of soil conditions. The evergreen broad-leaved trees community is transforming from the initial stage of Pinus densiflora and Pinus thunbergii through the stage in Quercus serrata to Castanopsis sieboldii and Actinodaphne lancifolia. The overall ages of the specimens were similar, and the oldest tree was the 59-year old Castanopsis sieboldii. The correlation analysis of major species showed a high positive correlation between Pinus thunbergii and Eurya japonica, Pinus densiflora and Fraxinus sieboldiana, and Actinodaphne lancifolia and Camellia japonica and a high negative correlation between Pinus densiflora and Carpinus turczaninowii and Carpinus turczaninowii and Eurya japonica.

To investigate the users' activity, impact and psychology in Naejang Temple district at Mt. Naejang National Park in Korea, users' density and questionnaire survey at three major picnic areas and passenger counting at major pass were executed and environmental impacton on the site was surveyed. The total number of visitors showed stability at the level of one million persons every year after 1984. Users' impact was much severe along the main trail, the upper cablecar station and the slope from the observatory to Keumsun Valley, The maximum momentary number of users was estimated as 53,000 persons in autumn. Approximately 20% of the total number of visitor used Keumsun Valley and Weonjeok Valley area and 80% of visitors left after using only grassland and cablecar. The visitors' characteristics was similiar to the type of long-distanced national park and the main visiting purpose was to see autumn leaves. The psychological satisfaction did not very significantly as to increasing user's speace. As a result of varimax rotated factor analysis, the 1st factor, most affecting users' psychological satisfaction, was related to landscape and consisted of nature disturbance, crowdedness, noisiness, cleanness, in order of importance. The 2nd factor was related to facilities and consisted of number of toilet, number of waste-baskets, amount of drinking water, safety, in order of importance.

Effects on noise attenuation of the hedge species, Thuja orientalis L. and Euonymus japonicus Thunb., widely used as road side hedges, were analysed at the frequencies of 1,000, 2,000 and 3,150 Hz., respectively. The present experiments were carried out both in the field and in a Semianechoic Chamber. As increasing the distances from the noise source, attenuation rates of noise level were increased at high frequencies. But the attenuation rates of the noise level at low frequencies showed varied as the distances increased, and this trend appeared to be caused by the influence of ground waves. Generally, in this experiment, Thuja orientalis L., which is a coniferous species, showed more effective on the abilities of noise attenuation than that of Euonymus japonicus Thunb., which is a broad-leaved evergreen species.

This study was conducted to determine the toxic effects of air pollutants on landscaping tress, Pinus densiflora, Pinus koraiensis, Ginkgo biloba, Liriodendron tulipifera, Platanus occidentalis and their resistance to the pollutant toxicity in urban and industrial regions of Seoul and Taejon, Korea. Total sulfur contents and enzyme activities such as superoxide dismutase and peroxidase were analyzed in tree foliage of Pinus densiflora, Pinus koraiensis, Ginkgo biloba, Liriodendron tulipifera, Platanus occidentalis. In addition, POD activity was analyzed in the foliage on tree seedlings, i.e. Pinus densiflora, Pinus koraiensis, Ginkgo biloba, Lirioderdron tulipifera, with the fumigation of $SO_2$ in gas chamber 4 hours a day for six days. In Ginkgo biloba total sulfur content and POD activity had a negative correlation while other species had a positive relationship in total sulfur content and enzyme activity. Air pollutants accumulated in tree tissues were supposed to enhance the enzyme activity like POD providing the resistance mechanisms. Especially Pinus koraiensis and Platanus occidentalis had higher POD activity than other species. The increase of temporary POD activity against environmental stress appeared in sensitive trees and prolonged increase of POD activity played an important role in resistance mechanism. SOD and POD activities in all species had a positive correlation except Ginkgo biloba. Changes of SOD and POD activities were different between species and in most species SOD as well as POD seemed to participate in resistance mechanism.

This study was conducted to provide basic information for development of habitat-based conservation strategies of biological diversity in agricultural ecosystem. The carabid beetle assemblages were examined at four kinds of habitats(levee, dike, forest patch remnants and streamside) from three differently stressed areas located in Paltan-myun, Hwaseong city, Korea: agricultural and forest area(site 1), industrial area(site 2), and residential area(site 3). Pitfall trap samplings were carried out 39 times from November 2000 to November 2002. Our study's findings were that the composition of carabid beetle fauna, dominance species, and pattern of carabid beetle assemblage were different among the habitats. The similarity index was highest between two levees in site 2 and 3, and lowest between hillock in site 2 and streamside in site 3, and that among habitats fragmented by road with high traffic was lower than that among any other habitat types. So, we could know that agricultural land use respectively do an important role in diversity conservation and networking. These findings will be used to establish the land use and management plans in the aspects of conservation of biodiversity.
