We have studied the Yang-San peatland area to make a conservation plan. Since the peatland has its own unique ecosystem, which provides important resources in studying transformations of ecosystem, vegetation, weather, and many other things, it is not enough to emphasize the importance of preserving this area. Based on our investigation, we propose the followings to preserve the Yang-San peatland area and use in environmentally sustainable manner. First, it should be designated as a Wetland preservation area to make a conservation system between government and citizens. Second, a monitoring system is essential to observe the change of ecosystem and prohibit trespassing. Third, a comprehensive and precise investigation is in need how to restore the ecosystem. Fourth, an educational information about the ecosystem should be provided through pamphlets, postcards, visiting centers etc.

To select the criteria, literature review was made in the quantitative case of conservation biology, foreign country's EIA and domestic ecology. Among them, a few factors was extracted. To applicate the criteria to domestic forest ecosystem, expert opinion survey was executed to the ecologist. The results were summarized as follows; 1. Classification of sites was made of land use system which is related to forest ecosystem or forest conservation. Sites are divided into 3 categories which are nature preservation area, seminature preservation area and urbanized area. Evaluation criteria is consisted of rarity and naturalness. 2. Each area had different criteria composition according to the site characteristics. Criteria of nature preservation area is rarity in the broad sense (distribution pattern of vegetation), vegetation size, successional stage and depth of organic matters. Those of seminature preservation area are rarity in the broad sense (distribution area of vegetation), vegetation size, successional stage, diameter at breath height and depth of organic matters. And those of urbanized area are vegetation distribution in area, successional stage, age of forest and diameter of breath height. The basic data of criterion was gathered by field survey. 3. Evaluation index and total naturalness index was obtained by adding the each criterion. It is made up of two categories-rarity and naturalness. TNi is divided into 3 grades. Grade I is more than 70% for TNi, grade IT is 50~70%, and grade III is below 50%. According to the each grade, permitted action and facilities were suggested.. This research just focuses on the evaluation of vegetation quality and the assessment results do not directly judge conservation or development. To make better evaluation criteria, various fields of forest ecosystem-geological or physical nature environment and fauna ecosystem etc. -will be added wholly to this research.

This study tried to propose the guidelines for the ecological preservation zoning in Korea. So some related laws and regulations were inspected, which were Natural Environment Preservation Act, Nature Park Act, Cultural Asset Conservation Act, Forest Act and Urban Planning Act. In these acts, I could find several concepts related to the ecosystem that are described as the protection area. But there aren't detailed and practical characteristics in those concepts. So for making the practical concept of ecosystem preservation, I considered Multiple Use Module, Wildlife habitat model, and Environmental evaluation model. Thorough this step, the process and methodology was established for evaluating and analysing. The potentiality of the GIS system was inspected. So the TM5 scene of the site was acquired and processed by ER-Mapper, Idrisi, Arc/Info and Arcview. And several digitized data were input by scanning and vecterizing. The Erdas format was mostly exchangeable to any program. The site is the Byonsan Peninsula National Park. The forest stand information and topographic data were digitized, types of which are forest year, DBH, density, slope, aspect etc. And also the watershed boundary, roads and paths, natural and cultural resources were mapped and analysed. Modelling of preservation suitability found the dispersed patterns for the best suitable zone through all the site. And the development potential areas were checked on downwatershed. This patterns are thought to result from the forest location for the wildlife habitat and the low altitude and no-steep slopes for developing. And Early warning system concept was introduced by overlapping these two patterns on the both potential area. As the conclusions, I proposed that the preservation zone be assigned according to the watershed unit as the main ecosystem zone. This main area should be linked by the eco-corridor through the point type eco-system. Finally, I thought the comprehensive information system should be established for making the rational and efficient decision making in natural area.

These studies had performed a plans for preservation and distribution of Ilex cormuta community Mt. Keumsung($35^{\circ}05'\;N,\;126^{\circ}04'\;E$) in Naju, Chonnam from Arpil, 1997 to October by Braun-Blanquet' method(1964). According to the vegetation table of community, the plant communities of the investigated sites were classified Ilex corunta-Trachelospermum asiaticum var. intermedium commnity. Now there still remains the natural environment to be developed in coast district around the riverside distributing Ilex cornuta Lindl., so it has scientifically high value to predict change of the ecosystem and preserve the community distribution. It needs plan for preservation high value to predict change of the ecosystem and preserve the community distribution. It needs plan for preservation

The purpose of this study is to provide a basic datd for establishing a basic park management plan for Bulamsan Urban Nature Park. This research surveys very closely about the present condition of the natural ecosystem based on the examination and analysis of the present condition. This research suggests development and management methods for environment-friendly park by understanding damages on the ecosystem due to overuse, as well as park facilities and their effects on the surrounding environment, using quantative analysis. The three steps: researching the present condition research, ecosystem evaluation, and park management plan were taken in order. The present condition research is based on the general condition, natural environment, and natural ecosystem data. In the ecosystem evaluation, wildlife habitats evaluation, landscape evaluation, and biotope type research which is a materialized form of the plant ecosystem were excuted based on the present condition research data. In the park management plan step, 1) classified ecosystem and landscae preservation zone, ecosystem protection zone and ecosystem restoration zone as ecosystem and landscape preservation plan, 2) plannings for ecosystem, fine landscape preservation, damaged area restoration and recovery plan were established in order to suggest environment-friendly plan,

Restoration ecology is undergoing rapid growth as academic field over the last 15 years. The specification of goals for restoration projects is frequently described as the most important component of a project. The endeavor for universal development of goals for ecological restoration continues to generate many discussion and controversy. I discuss the importance of restoration goals and diverse roots of restoration ecology, and show how the complex lineages within restoration ecology. I review the three major theme that currently are used to develop the restoration goals : restoration of species, restoration of whole ecosystem or landscapes, and the restoration of ecosystem services. Restoration ecology, landscape ecology and conservation biology share goals to conserve biodiversity, but differ in focus of approach. I review the differences among three fields. Conservation biology has been more zoological, more descriptive, and theoretical, and more emphasized the population and genetic research. However, restoration ecology has been more plant ecological, more experimental, and emphasized the community and plant succession. Landscape ecology has emphasized the interaction of ecosystem and dispersal among populations. I suggest the integration of restoration ecology, landscape ecology and conservation biology. For example, conservation biology will contribute to the preservation of original habitats by population study, restoration ecology will contribute to regenerate damaged ecosystem and ex situ preservation, and landscape ecology will contribute to restoration of population and landscape.

Industrialization and modernization of the $20^{th}$ century have brought convenience to human life. However, such development produced unintentional global environmental issues such as destruction of natural ecosystem through excessive use of the natural environment beyond its capacity. The United National (UN) recognized such global environment issues and coordinated with worldwide experts to conduct a comprehensive assessment of the global ecosystem, "Millennium Ecosystem Assessment (MA)", to resolve the issues. The UN conducted the MA primarily to comprehend the correlation between the ecosystem and human welfare. The results demonstrated that the ecosystem provides various direct and indirect benefits to human. This new concept was introduced as the "ecosystem services". Introduction of the ecosystem services highlighted the significance of the ecosystem and led to increased research and active discussions among experts from various discipline over the recent 10 years. It has been considered that the ecosystem service concept could be incorporated in policymaking process, as primary criteria to assess and weigh the benefits of using natural resources against the effects on value of the ecosystem. The current policymaking process is affected by the contradicting logics of modernization and preservation of ecosystem. The ecosystem services concept could be the answer to forming a rational policymaking process, allowing for nature preservation while wisely using the available natural resources. The general consensus has been formed on the need of incorporating the ecosystem services concept in the policies and globally various researches on the ecosystem services have been actively conducted. However, introduction of the ecosystem services concept is still at a very early stage and research on real application of the ecosystem services is yet almost nonexistent. Also there are no clear and agreed definition, classification scheme and value appraisal methodology regarding the ecosystem services. Therefore, this research explains the basic concept of the ecosystem services and highlights specific issues for further researches, as further researches on real application of the ecosystem services would find ways for the ecosystem services approach to be valuable in the policymaking process.

This work aims to collect a biogeographic informations on the biota, alpine ecosystem, nature reserves, forest ecosystem of North Korea, and also to accumulate a basic data on the current situation and problem of the natural ecosystem of North Korea for the preparation of future cooperation and exchange between South and North Koreas. The obtained findings are as follow. First, North Korean biota contains 18,013 species, and consists of 6,710 plant species, including 3,860 species of vascular plants. Secondly, urgent investigation on the biogeographically important arctic-alpine and alpine plants and ecosystem, those are known to be endangered due to environmental change and global warming, is required. Thirdly, the conservations of diverse nature in North Korea are conducted by the introduction of various systems, such as nature preservation region, reserves for plant, animal and sea bird, and natural monuments. Fourthly, out of 9.5 million hectares of forest, one million hectares have already faced forest denudation, thus caused lots of damages for forest ecosystem. Sharp decline of North Korean forest land are due mainly to the expansion of terraced dry-field farming and deforestation. Recovery of denudated forest land should be approached by both South and North Korean sides to solve the problem of shortage of foods and restoration of natural ecosystem of North Korea.
