Under the 「National Land Planning and Utilization Act」, Development Restriction Zones(DRZ) is one of the designated use district where the Minister of Land, Infrastructure and Transport deems it necessary to control urban development in order to prevent urban sprawl and conurbation and ensure a healthy living environment for citizens by conserving the natural environment surrounding metropolitan cities. DRZ was first designated around the Seoul Metropolitan city in 1971, and had been expanded to the 14 metropolitan areas across the country since 1977. The designated areas were accounted for about 5.4% of the total national land and its importance was demonstrated by contributing to control urban sprawl, curbing real estate speculation, and providing green space to citizens. However, DRZ has been repeatedly relaxed its regulations and allowed development under government. As a result, much of the green areas was damaged and several cities were merged and extended(conurbation). In particular, deregulation implemented for the purpose of securing land as part of national projects and local outstanding business(i.g. constructions of national rental housing, industrial complex, and international stadium) have caused continuous environmental damage around the metropolitan cities. In addition, the habitat fragmentation is in serious situation. Thus, the systematic plans for managing DRZ are necessary, since it is concerned that urban environment become deteriorate in the mid- to long-term. This study aims to continuously protect the urban environment from lifting DRZ. Therefore, firstly, we examined the environmental status through analyzing DRZ Management Plan which shall be drawn up by the Special Metropolitan City Mayor, the Metropolitan City Mayor or the Mayer/Do governor having jurisdiction, every five years to collectively manage DRZ. Secondly, we investigated the actual condition in DRZ based on the case study of Management Plan in Metropolitan areas(i.e. Seoul Metropolis, Gyeonggi-do, and Incheon Metropolis). Finally, we suggested the seven feasible improved political plan for managing DRZ.

Ji Cheng''''s great work on garden design theory, the ''''Yuanye'''', written in 1631 and originally published in 1634 is the first surviving treatise and most famous and comprehensive work on the suvject in the Chinese tradition. He constructed Dongdiyuan in Changzhou about 1623, Wuyuan in Yizheng in 1631, and Yingyuan in Yangzhou about 1634. But no poems and paintings written by him still exist, and none of his known gardens has survived. Therefore his design philosophy is able to be interpreted only by his work, Yuanye. This study aims at investigating the garden design theory in Yuanye. The results were summarized as follows. 1) Yuanye reflected the garden tastes of literati, and Ji Cheng endeavored to express the deas of literati painting into gardens. 2) The essence of the garden design theory is Xingzao, and Yindi, following the existing lie of the land, and Jiejing, to borrow from the scenery, are two major activities of Xingzao. 3) Ji Cheng''''s design theory build up on the basis of recognizing the existence of masters. 4) Yindi is the environmental and ecological planning and design method. This is the activity to reach the state of artistry through suitability. 5) Jiejing is not merely borrowing the landscape but the making use of scenery around the garden. And only the master has the skill in fitting in with the form of the land. 6) Ji Cheng pursuits the garden which will look like something naturally created though manmade. It is the goal of the Chinese traditional gardens and ideal situation. 7) Ji Cheng aims to unify the environment and landscape design dialectically into Xingzao.

This study modified and applied the ecological network(Indicator 2) from the City Biodiversity Index(CBI) to be tailored to Korea. It is calculated by utilizing a biotope map and a land cover map. The ecological network of Gyeryong-Si was 13,713,703(33.8%) with the biotope map and 17,686,966(37.9%) with the land cover map. The result of the biotope map was lower than the land cover map. The ecological network of Goyang-Si was 4,961,922(4.9%) with the biotope map and 4,383,207(3.7%) with the land cover map. The result of the land cover map was lower than the biotope map. As a main result of the research, an error was discovered in which, when calculating the ecological network, the types of the military unit facilities were distinguished into a special area on the biotope map and into an urbanization promotion area and a forest area on the land cover map. In the case of a middle-classified, land cover map, the land use in the surroundings of the forest area was not subdivided. An error in the development area expressed as a forest green was discovered. When selecting the natural elements, too, regarding the types of artificially-created rivers, artificial ponds, and artificial grasslands, etc. on a biotope map, the exclusions were necessary. Regarding the natural, bare ground on a land cover map, there was a need to calculate by including the natural elements. It was judged that, in the future, the ecological network in the unit of the entire nation can be analyzed roughly by utilizing a land cover map. It was judged that, in a city having a biotope map, the calculation of the ecological network utilizing a map of the present situation of the urban ecology will be a more accurate diagnosis of the present situation.

Weed is one of the problems in the crop land as well as in uncultivated land, raising the farm management costs. Therefore, the weed control is essential for effective agricultural management. The cost for weed control in Korea occupies on the average 27.6% of the total labor cost required. Agricultural policies since 1960 were transferring from yield increase due to land productivities to increase of income due to labor productivities. Therefore, the weed control by hand is also changed to weed control by chemicals. The weed control by chemicals has also brought about some side-effects and needs better, improved weed control methods. The present weed control situation and related problems were studied to present new approaches for agricultural development in the future. There were 458 species of weeds in 82 families which were growing in the crop land. The weeds to control, however, are 12 in paddy field and 9 in upland. So far weeds in paddy field are well under control, while weeds in upland are poorly controlled due to change in chemical efficiency and chemical damage in the upland. The administration, research and extension work for the efficient use of agricultural chemicals have been done by various institutions, such as Office of Rural Development, Office of Forestry, and chemical companies. The courses for agricultural chemicals were offered in the agricultural colleges. However, the efficiency of chemicals could not be maximized due to the poor relationships among related institutes. The newly established Agricultural Chemical Research Center at the Office of Rural Development and the Korean Weed Science Association are expected to contribute toward improving weed control in Korea. The Korean agriculture in the future will eventually be mechanized and the varieties resistant to high nitrogen application and to high plant density will be required for high yields. The rice will be transplanted earlier and the whole growing period will be extended. The application of organic matter will be increased for increasing soil fertility, and the use of agricultural chemicals will be continued. Under such a condition, the studies on the weed occurrence and its integrated control measures will be needed. Also weed controls in the newly exclaimed land, crop varieties, horticultural varieties, forage crops, and forests are also needed to study. Basic and practical researches for the weed control to improve the labor productivity will be also needed. In order to meet the all requirements for efficient weed control, weed control systems including all the academics, research and extension workers, administratives, farmers and companies should be established. Also securing researchers and education of personnels are pre-required and research funds for the chemical studies should be provided efficiently and timely.

Since 1990, urban areas have been expanded rapidly due to the concentration of the population and several development projects including large scale apartment complexes and residential developments. Due to these development projects, the quality and functions of ecosystems have been continuously degraded, regardless of public agencies' efforts introducing development index, guideline, and amendment of law for sustaining the quality of ecosystems. Substantial guideline and content cannot expect the sustainable maintenance of nation's natural resources. Recent improve this situation, ecological planning was introduced, but research data of environments and objective systems were not enough showing the limits. The purposes of this study were to reduce the urban sprawl caused by residential development plans for environment-friendly residential developments, to establish applicable ecological planning, and to suggest the land use plans that reduce adverse effects of developments to nature ecosystem.

The purpose of this study is to understand the trends of urban housing in the age of modernization in Western cities since 1970's, and to provide the useful data for diversifying urban housing types in Korea. Although the housing types can be categorized in many ways according to the points of view, this study classifies 11 types by a criterion of urban composition elements. Among 11 urban housing types, one type, free-standing slab structure, has been mainly applied to Korean situation. The reason might be that the free-standing structure type is the most efficient one in terms of land use and block organization, but it results in a monotonic condition of urban housing blocks. Therefore, taking local characteristics and urban contexts in Korea into consideration, the future urban housing design should be developed in different ways of making local life styles possible in them, by adopting various types of Western urban housing precedents.

Reading room in the university is one of necessary facilities that university student must use. It is, therefore, very important to make reading room comfortable acoustically not only to minimize the annoyance to the users but also to provide efficiency in studying. Present study aims to investigate the current situation of reading room in terms of acoustics and moreover to find out the relationship between the indoor noise and users' satisfaction through questionnaire survey. As a result, the indoor noise level is quite higher than the 1st grade, 35 dB(A), that the Ministry of land, transport and maritime affairs suggests as certificate regulation for environment friendly building and there were lots of noise sources that can provoke users in studying or concentrating. Questionnaire survey illustrates that the sound when opening and closing door, and airborne sound from outdoor transmitted through window are most annoying, which affected users' dissatisfaction.

NDVI has been used to estimate several ecological variables including leaf area index (LAI). Global MODIS LAI data are partially produced by empirical model that is based on the assumption of high correlation between NDVI and LAI. This study attempts to evaluate the MODIS empirical model by comparing with the result obtained from field LAI measurement and Landsat ETM+ reflectance. MODIS LAI product and ancillary data were analyzed over a small forest watershed near the Seoul metropolitan area. The relationship between NDVI of ETM+ and field measured LAI did not correspond to MODIS LAI estimation. Since the study area is mostly covered by very dense and fully closed forest, the correlation between NDVI and LAI might not be high. Although MODIS LAI product has great potential for global environment studies, it needs to be cautious to use them in regional and local area in particular for the forest of dense canopy situation.

Owing to the industrialization, the urbanization and cultivation abandonment actual condition, the most abandoned farmlands increased. Those results have occurred inefficient land use and destruction of agricultural ecosystem with the secondary succession. The research for the abandoned farmlands of Korea is fundamental phase. Also, the researches to restore abandoned farmlands are something yet to develop and not established the restoration for ecological value of abandoned farmlands. The objective of research revealed the ecological functions of abandoned farmlands and it presented an application plan. The research method divided in the literature and case study. Using abandoned farmlands, Japan government tries to create the ecological parks for the conservation of a vulnerable plant species, dragonfly biotope, environmental education and research, etc. Accordingly, the goal for the abandoned farmlands coulds be set suitably to Korean situation as of Japanese styles which are characterized by man-made biotopes.
