This study was conducted to analyze the text relating to the environmental conservation and ecology among the text of the constitution of Korea and collect the domestic laws(40 statutes, 1 guide, 1 leading case) and the foreign laws(1 constitution, 34 statutes, 2 ordinances, 3 leading cases). To make the text of the collected domestic and foreign laws a comparative analysis of the conceptual principle, plan establishment and project operation, types, policy and allied projects, rights and duties, allowed and restricted acts, environmental impact assessment and administration procedure and system of the environmental conservation and ecology by items, it was considered to the mutual relation with lots of laws which are scattered with the various laws and studied to how to set the many foreign countries on their laws connected with the environmental conservation and ecology from the other department and carry out the advanced environmental works.

Studies on rare and endemic plant conservation should be performed nationally to conserve plant diversity. Studies targeting a specific taxon have been reported based on the necessity of conserving plant diversity. From this point of view, there is an increasing necessity to compare and evaluate the studies for conservation. Moreover, it is necessary to analyze and review the direction for study subjects and items required for effective conservation of rare and endemic plants in Korea, based on the analysis results of collected data. We analyzed trends of studies on rare and endemic plants worldwide. In particular, we collected and analyzed the study trend in Korea. Study fields of the rare and endemic plants were divided into six classifications, of which the conservation ecology classification was sub-divided into the species traits, population study, and biological interaction. We have collected conservation ecology studies showing significant differences in regions and countries. They have been actively conducted in Europe and North America by region and in Japan and the United States by country. On the contrary, studies on basic ecology accounted for the most, followed by conservation genetics and restoration ecology in Korea. It was revealed that the portion of conservation ecology conducted in Korea was lower than that of the world. Moreover, studies mainly focused on a specific taxon of rare and endemic plants, such as endangered plants designated by the Korean Ministry of Environment. Particularly in Korea, conservation genetics and restoration ecology studies accounted for high percentages. Considering the worldwide study trends, particularly those in Europe and North America that lead the study of conservation ecology, we suggest approaches to increase the percentages of conservation ecology, including securing the information on species traits, population structure and population dynamics, and interaction between animals and plants are necessary for effective conservation of rare and endemic plants in Korea.

Mathematical biology has been recognized its importance recently and widely studied in the fields of mathematics, biology, medical sciences, and immunology. Mathematical ecology is an academic field that studies how populations of biological species change as times flows at specific locations in their habitats. It was the earliest form of the research field of mathematical biology and has been providing its basis. This article deals with various form of interactions between two biological species in a common habitat. Mathematical models of predator-prey type, competitive type, and simbiotic type are investigated.

Human being has extensively invaded, occupied, and used the natural environment as a consequence of the advance of civilization. Mankind has increasingly modified the environment for his own benefit. Such modification has not only caused the extinction of many other species but also, caused human being himself to confront to serious environmental problems. The recognition of this fact by human is expressed in the establishment and development of restoration ecology. This new study fold is, in fact, an "Eco-technology" directed towards healing of damages to the environment. The goal is to reestablish processes and functions in a damaged site, imitating the way of healing works that an integral natural system carries out. Ecological restoration uses different treatments and approaches according to extents of the existing damage and to the specific goal to be achieved. An ecological diagnosis is, therefore, required prior to restoration practice. The cost and efforts to achieve a proposed goal can be significantly reduced when a restoration plan is formulated upon the results of well-conducted ecological diagnosis. Under such perspectives, restoration ecology is a practical science, which aims to solve the problems of the real world based on the existing ecological principle. Furthermore, restoration ecology offers opportunities to test the ecological concepts and theories obtained by means of the former ecological studies. Human being exploited natural environment excessively for his comfort on one hand but damaged it inevitably on the other hand. Such intensive resource utilization and continuous environmental damaging will extend into the future and ultimately jeopardize the survival of humankind if no prompt action is taken. In the present situation, we must not continue such lives without any preparation. We have to cope with the environmental crises approaching near us by pursuing the ecological restoration that reduce the unnecessary use, recruit the deficient part, and strengthen the weak portion in our environment. Restoration ecology could be recognized as the ecology for the future in such viewpoints.

낙산복원사업 대상지의 생태계 회복을 위한 계획수립의 기초자료로 사용하기 위하여 부지 내 식생조사를 통해 자연환경을 평가하였다 현존식생도 녹지자연도 및 Hemeroby 등급을 통해 자연성을 평가한 결과 많은 면적이 산림으로서의 기능을 상실한 인공화된 지역이었다. 식생이 존재하는 지역 중 산림의 형태를 유지한 지역은 아까시나무군락을 유지하고 있었고 기타 지역은 휴경지, 논.밭 잡초군락이며 동시에 ruderal 식물군락으로 판명되었다. 성과주변에 식재한 수목은 총 67종 1,243개체였으며 그중 자생종이 27종(40.3%) 544개체(43.8%)였고 도입종과 귀화종 재배종이 각각 17%, 8.8%, 15.4%로 나타났다. 생활형 분석에서는 1,2년생 초본식물이 47%를 차지하였고 귀화율은 24.1%로 나타나 매우 불안정하고 교란된 환경인 것으로 판단되었다.

The wetland in the city could be mainly divided into the deep water type and the abandoned paddy type, so this study was conducted to analyze characteristics between the two types of the wetland. The former sample site was located near the Olympic village in Songpa-gu of Seoul, and the latter sample site was in front of the Mt. Bukhan fortress in Eunpyeong-gu of Seoul. The actual vegetation, vascular plants, and avian fauna were researched. In the actual vegetation, the deep water type had the broad surface of water and the emerged plant as Phragmites communis have grown widely, but the abandoned paddy type had the narrow sur-face of water and hydrophyte as Persicaria thunbergii have grown widely. It might be judged because the water depth of the abandoned paddy type were shallow wholly. And the floating-leaved plants and the free-floating planktonic plants were not observed such as Nymphaea tetragona var. angusta, Lemna paucicostata in the abandoned paddy type wetland. The wild birds were mainly observed at the edge of the wetland(at the edge of woodland) in the abandoned paddy type, but were observed equally in the deep water type. 28 families 433 species were observed at the former site and 32 families 365 species were observed at latter site. It was judged that the various topographical structure(habitat diversity) might make all items various.
