Recently, habitat fragmentation and shrinkage has occurred because of increased road construction. As a measures mitigating the adverse effect such as eco-island by road construction, Korea has been installed eco-corridors since 1995. Using the Analytic Hierarchy Process (AHP), this study analyzed the importance of assessment items and the criteria to determine which areas require eco-corridors the most. First, related literature reviews, preliminary surveys, and expert interviews were carried out to develop assessment items and criteria for constructing the hierarchy. Second, experts were surveyed in order to determine the relative importance of the assessment items by applying the AHP. As a result, it found that the restoration of the ecological network was the most important assessment item, followed by wild animal resources in the Level 3. In the Level 4, the eighteen items were ranked in the order of their relative weight and it was found that the 'Baekdudaegan Mountain Range (0.189)' was the highest ranked item. Therefore, this approach can be applied to effective selection of the priority areas in planning eco-corridors in the national scale.

Recently, there have been many projects regarding restoration of streams to recover their environmental and ecological functions. For the restoration of streams, it is valuable academically and economically to evaluate the ecological condition of streams and build a plan and an object for restoring streams based on that. On the other hand, one of the methods to figure out the ecological condition of streams is to evaluate the hydromorphological structure of stream. In this study we have developed a field survey system using the stream assessment methode of LAWA (Laenderarbeitsgemeinschaft Wasser in Germany) that can assess the hydromorphological structure of small and medium streams. In addition, we constructed a GIS-based stream assesment system which can support auto mapping system and report writing, using the survey results. These systems are aimed to help people in the area of restoring streams perceive the natural and ecological condition of streams in the process of making plans and managing the projects, and they also try to help in collecting raw data to determine an ideal potential model to which an existing stream should be turned.

The purpose of this study is to critically evaluate the DPD development plan of Kyungpook province, which was established in 1996 and slightly revised in 1997 in terms of a theoretical framework, fair distribution and ecological sustainability, and the feasibility of capital supply of the proposed plan. The early part of the proposed plan introduces various theories and approaches developed in regional (or local) development planning as a general after the 1970s. However, the theories and approaches mentioned are not used as a guideline to establish the DPD development plan of Kyungpook province as a historically developed particular place. Most of the plans were tourism-oriented and did not seriously take the local characteristics into account. All the DPDs of Kyungpook province are located in the upper parts of the Nakdong River basin. So those regions are ecologically vulnerable. But a lot of problems remain concerning the environmental impacts of the proposed development plan. In terms of fair distribution and ecological sustainability, it seems that the DPD development plan was routinely made by a handful of professors and administrators, based on a standard format of regional (or local) development as a genera]. Finally, capital is the key factor for successfully implementing the DPD development plan. It came from the national and local government and private investors. The government have generally financed the construction of infrastructures, not profit-oriented projects such as tourism and resort businesses. However, the feasibility of private capital was not carefully examined in the plan.

As the imports of foreign agricultural products are liberalized and the consumption of agricultural products declines, abandoned rice paddy fields continues to rise. However, such abandoned rice paddy fields has not been precisely surveyed yet. In this backdrop, a necessity to develop technology to utilize such abandoned rice paddy fields has emerged. Utilization of abandoned rice paddy fields as wetlands may be a good example. This study aimed to survey the current status and characteristics of wetlands created within abandoned rice paddy fields by selecting abandoned rice paddy fields throughout the nation and conducting field surveys on the sites that had transformed into wetlands. The abandoned rice paddy fields almost transformed into wetland and the types of wetlands transformed from abandoned rice paddy fields were mainly Inland/Moutain/Depression/Abandoned rice paddy fields/Marsh/Phragmites communis community and Inland/Moutain/Depression/Abandoned rice paddy fields/Swamp/Salix koreensis community. Abandoned rice paddy fields that had transformed into wetlands was depending heavily on waterways for water supply than other reservoirs and lakes do. Abandoned rice paddy fields transformed into wetlands was most observed in mountainous area. Abandoned rice paddy fields are because agricultural land is no longer profitable due to international and social changes and is not cultivated as government policy. Wetland period and dimension originated from abandoned rice paddy fields are very various and its surrounding land its mostly forest and the next largest follow roads and rural community. The abandoned rice paddy fields transformed into wetlands is mostly deserted currently. Despite their value as wetlands, no restoration and utilization efforts are made in Korea today. Therefore, it is imperative to conduct a precise current status survey on these areas and introduce management and restoration plans at the government level in the case of important habitats.

After the Rio declaration on environment and development in 1992, developed countries are undertaking 'environmentally sustainable transportation (EST)' projects. To meet the needs for EST, current transportation policies in Korea are rapidly reforming and one of its concerns is modernizing and upgrading railway freight system. Planning new railroad construction projects is increasing and subsequent environmental impact assessment (EIA) demands improvements, especially in both the EIA and decision making systems. In this paper, we discuss the present status of EIA for railroad construction projects, especially, by analyzing the EIA documents accumulated for last six years. The EIA for railroad construction projects .accounts for only $4.9\%$ of total project EIAs during 1998-2003. However, the portion is gradually increasing. Major environmental concerns for EIA in railroad construction projects were geomorphological and ecological changes, protection of rare organisms, air pollution, water quality, wast management, noise, etc. We also compared the characteristics of environmental impacts of railroad construction with those of vehicle road construction. The result shows that railroad construction usually requires 3${\~}$4 times longer tunnels and bridges for a given length than vehicle road construction. In addition, the amounts of geomorphological and ecological changes (road-cutting, embankment, devegetation, etc.) in railroad construction were generally less than $40\%$ of those in vehicle road construction. In order to develop environmentally friendly railway systems, monitoring studies for environmental impacts of railroads such as habitat fragmentation and road kills, dispersal of alien plants, tunnelling effects on groundwater and vegetation, and noise impacts are highly required.

The agricultural landscape is considered an important space to provide service functions, but the reality is that environmental and ecological problems are being reported in the creation of a facility horticulture complex. Therefore, this study was conducted to contribute to sustainable agriculture by creating a more eco-friendly facility horticultural complex. The elements of planning for eco-friendly development of the facility horticultural complex were derived from literature and expert surveys. The master plan and the bird's-eye view were then applied to the Saemangeum area by applying the planning elements. After analyzing the method of selecting and deploying input elements for improving functions, it was suggested that low-flow areas, wetlands, artificial storage facilities, green spaces, and waterways should be placed in harmony with the landscape and that the building-to-land ratio should be applied at 55%. The final design was prepared by applying the ecological service function improvement plan proposed by experts. The final bird's-eye view also reflected water purification facilities, connection of wetlands to waterways, packing of pitchers, and connection of green areas. The results of the research are expected to be used as basic data for policy and budget allocation for the eco-friendly creation of horticulture facilities and contribute to sustainable agriculture by contributing to national biodiversity and environmental preservation.

We accessed the climate change effects on the distributions of warm-evergreen broad-leaved trees (shorten to warm-evergreens below) in the Korean Peninsula (KP). For this, we first selected nine warm-evergreens with the northern distribution limits at mid-coastal areas of KP and climate variables, coldest month mean temperature and coldest quarter precipitation, known to be important for warm-evergreens growth and survival. Next, species distribution models (SDMs) were constructed with generalized additive model (GAM) algorithm for each warm-evergreen. SDMs projected the potential geographical distributions of warm evergreens under current and future climate conditions in associations with land uses. The nine species were categorized into three groups (mid-coastal, southwest-coastal, and southeast-inland) based on their current spatial patterns. The effects of climate change and land uses on the distributions depend on the current spatial patterns. As considering land uses, the potential current habitats of all warm-evergreens decrease over 60%, showing the highest reduction rate for the Kyungsang-inland group. SDMs forecasted the expansion of potential habitats for all warm-evergreens under climate changes projected for 2050 and 2070. However, the expansion patterns were different among three groups. The spatial patterns of projected coldest quarter precipitation in 2050 and 2070 could account for such differences.

In recent years, the population structure has been changed by the progresses of 6th-industrialization and transportation in farming areas. This study aims to suggest a regional development plan of farming areas in accordance with the demographic changes. Population structure indicators were derived from previous studies and literature review in order to identify the types of farming areas. Demographic indicators separated to depopulation and population growth in farming areas through a standardized scoring method. This research found that the division of economy is not only the most important division in any other regional development divisions but also necessary to develop new sources of non-farm income through traditional culture, natural environment. In the social division, it is necessary to secure the facilities for the formation of a sense of community to multicultural families and existing residents in farming areas. In the environmental division, it is desirable to improve the quality and satisfaction of life for residents such as the sidewalk and park that utilize ecological environment, culture, history for both depopulation and population region. In the physical division, there is a need for improvement of the facilities of basic living infrastructure service such as roads, water supply and sewerage systems. In the institution division, sustainable financial support of the central government policy for farming areas is crucial for the improvement of residential environment in the farming areas of depopulation and population region.

Agricultural tourism is a new kind of industry, which combined agriculture with tourism. It not only has the productive function, but also has the function of improving the quality of ecological environment and supplying people with sightseeing, leisure, vacation. Agricultural tourism is a new kind of industry from the amalgamation of agriculture and tourism: it is based on farm work, characterized by agricultural management, combines agriculture and tourism, and includes the city as a market-place. It satisfies tourist demand with food, lodging, excursions, shopping and entertainment provided by agricultural places and agricultural products. After combining the substance of this study with the primary sources regarding the development of agricultural tourism, I suggest plans for the development of local agricultural tourism on the basis of sustainable tourism theory in case of the Inner Mongolia region. To conduct research, various data such as literature research and surveys are collected and analyzed. According to the result of the research, the Inner Mongolia region has great-wealthy resources for agricultural tourism. However, they have problems as well such as lack of funds, low infrastructure, low business-mind level, low management-mind, the scarcity of mid-supporting organizations for research and education, low awareness, and low service level of the agricultural tourism. In order to solve these problems, have to strengthen publicity, strengthen the county and city communication, educates continuously profession talented person, establish related laws and regulations, increase the integrity of infrastructure. As a developing industry, agricultural tourism is a new field of study which needs more encouraging research. The agricultural tourism of Inner Mongolia Autonomous Region has only just started development resulting in a limited amount of information available for this study. Future planned work entails a continuous in-depth study of Chinese agricultural tourism, considering Inner Mongolia Autonomous Region in particular.

A purpose of this study is to develop practical indexes for improving a village environment in Kyongbuk, Korea. From a questionnaire survey of the public employees (71 persons) who take charge of the environment in Kyongbuk province, the indexes were produced and the contents of questionnaire consisted of preferential and supplementary indexes to apply. The preferential indexes which apply to an agricultural village and a stock raising village are environmental sanitation facilities, a hygienic check of livestock and a purge of livestock shed's surroundings. In case of mountainous village, and natural-ecological village the preferential indexes are habitat reservation for wildlife, poaching prohibition (monitoring for it), and food supplement for livestock. To the traditional-cultural village, prevention of noise pollution, environmental sanitation facilities, and a monitoring or water quality change are the prior indexes in order. For the village near city and the industrial village the preferential indexes are patrol removing of garbage, pollution index planting and monitoring for noise pollution. For a fishing village and a village fronting waterside excess uses of agricultural chemicals, monitoring for a water quality change, and realignment of green house with vinyl and warehouse. In conclusion the research presents the practical and preferential index for residents to improve their environment in accordance with village settings and suggests guidelines for further research.
