This study was conducted to examine the effects of trampling on the changes in soil and vegetation around the trails. The study areas were established both on the trails and in the forested areas located in Ui and Jeongnung valleys at Pukhansan National Park. Soil core sampling, measurements of vegetations and counts of persons visited per hour were done during the period from April 6 to October 9, 1986. The physical properties of soils became better with increasing distances from the trail, and the best conditions were observed in the forested areas. The differences were not significant among the zones within the trailside. More number of individuals and basal area (or coverage) in woody plants were observed in the forested areas than at trailsides. For the herb layer, however, more number of individuals and coverage were shown at the trailside. In the Ui valley, the duantitative measures of herbaceous plants decreased as the bulk density and penetration resistance increased. In the Jeongnung valley, however, only bulk density was negatively related to the quantitative measures. The fact that there were poor relations between soil factors and quantitative measures of herbaceous plants in Jeongnung valley might be influenced by other factors rather than soil compaction. Thus, more research would be needed to understand the critical factors affecting the vegetational changes in recreation areas.

This study was conducted to evaluate the functions of green spaces for the environment amelioration in Chongju City. The results obtained from this study were as follows; 1. Total amounts of $SO_2$ and $NO_2$ which can be absorbed by green spaces in Chongju City from EPA model were calculated as 27,655 tons and l,551 tons per year, respectively. 2. It was estimated that more green spaces were needed to mitigate the effect of air pollutants emitted from industrial complex at Songjung-Dong, Bokdae-Dong and Sachang-Dong in Chongju City. This is acquired as a result of overlaying the map of administrative district, forest state, and $SO_2$ isoline using GIS method. 3. The amounts of green spaces and the selection of their proper location have to be considered at the stage of city planning and in this case, the amounts of air pollutants are also considered.

최근 멸종위기 종에 때한 보전, 복원프로그램은 세계적인 추세일 뿐만이 아니라 국내에서도 자연환경보전법으로 보호를 받고 있다. 본 연구는 국내에서 멸종 위기에 처해 있는 붉은점모시나비가 상주-영덕 고속도로 계획노선에 의하여 서식지의 일부를 관통하거나 인접하여 이 지역의 개체군을 대체서식지로의 이주가 결정되었다. 이에 대체서식지의 조성에 앞선 선행 작업으로 위치 선정을 위하여 Mark-Release-Recapture (MRR) 방법으로 가상이동모텔을 적용하여 패치의 연결성을 추정하고 개체생존이주율을 산출하여 대체서식지 위치선정의 평가 자료로 활용하였다. 그 결과, 붉은점모시나비는 패치간의 거리가 약 250m 이내의 범위에서 50% 이상의 연결성과 개체생존이주 가능성을 보였으며, 나비의 이동거리를 추정에서는 평균 300m로 나타났다. 그리고 나비의 분포특성에서는 인접한 여러 개의 서식지 패치를 개체들이 이주를 하면서 순환 발생하는 메타개체군을 이루고 있다. 대체서식지의 위치를 결정하기 위하여 연구 결과에 따른 지역, 해당 지역의 지방자치단체의 추천지역, 그리고 훼손지역의 가치를 상쇄할 수 있을 정도의 중요도가 있는 지역을 예비 선정하였다. 그리고 이 지역들을 나비의 생태, 생태기반환경, 관리방안, 위험요소, 시공요소를 평가를 한 결과, 의성군에서는 5 안(안사면사무소)이 관리방안에서 높은 점수를 얻어 선정되었다. 이번에 평가된 항목에서 나타난 바와 같이 대체서식지의 위치 선정에 있어서는 대체서식지 조성이 가능한 예산의 범위, 서식지 관리주체의 선정, 현지 주민과의 협의 등 여러 가지 문제를 복합적으로 고려하는 것이 높은 비중을 차지하였으며, 생물학, 생태학, 경관생태학, 생물지리학, 생태공학, 조경학, 인문학 등의 다양한 분야의 참여로 얻은 결과물을 융합하여 반영하는 것이 필요하다는 것을 제언하고자 한다. Establishing conservation programs to protect and maintain populations of endangered species are not only a global trend, but also a pursuit endorsed by the Korean Environmental Conservation Act. This study evaluates the feasibility of alternative habitat patches for the endangered butterfly Parnassius bremeri. A portion of habitat of P. bremeri is expected to be fragmented and damaged due to the scheduled construction of the Sangju-Yongduk Highway. A trans fer of the habitat patches of P. bremeri is also scheduled. In order to select an alternative habitat patch, the Mark-Release-Recapture (MRR) method was used to simulate a patch transfer model. The connectedness between habitat are as and the survival of local populations were evaluated for each candidate habitat. It was found that metapopulations with patch distances of <250m showed a 50% connectedness and survival rate in local populations. P. bremeri were expected to migrate at an average distance of 300m. In addition, P. bremeri formed a metapopulation that exhibited intimate patch dynamics that promoted persistence among these patches. Possible candidate habitats including those recommended by local governing bodies were evaluated along with habitats that may counter problems arising from the damage done to the original habitat and habitats that may have a compensatory value equal to that of the original habitat. Based on these criteria, Ansa-myeon township office was selected due to its high scores. This scoring was based on a consideration of a wide range of variables that mark a successful transfer of habitat. These include the amount of funding available, the governing bodies of the possible alternative habitat, and the Expected collaborative effort of local citizens. This decision was collaborated on by incorporating the expertise of various fields of study including biology, ecology, biogeography, ecological engineering, landscape architecture, and social sciences. Therefore, it is suggested that in order to evaluate an alternative habitat for organisms, many social issues as well as ecological issues must be considered.

종에 대한 생태적 특성과 서식지에 대한 이해는 종의 보전에 매우 중요하다. 본 연구는 멸종위기에 처해있는 붉은점모시나비의 생태적 특성을 바탕으로 서식지 패치네트워크를 분석하였다. 그 결과 포획 개체수는 188개체, 재포획은 220회 되었다. 그리고 암수의 비율은 42:146개체로 암컷보다는 수컷이 약 4배 많은 것으로 나타났다. 또한 개체의 평균생존일수는 $3.93{\pm}3.93$일(수컷: $4.0{\pm}3.9$, 암컷: $2.5{\pm}1.0$), 암컷과 수컷의 최대 생존일수는 각각 13, 14일 나타났고, 수컷이 암컷에 비하여 오래 생존하는 개체가 많은 것으로 나타났다. 종의 평균이동거리는 377 m을 보였으며 최대 1550 m까지 이동하는 것으로 나타났다. 패치연결성과 개체생존이주율의 추정에서 패치간의 거리가 약 300 m 이내가 종의 이주에 적합하며 600 m 이상 떨어질 경우 개체생존이주율이 급격하게 감소하는 것으로 나타났다. 또한 종의 이주 빈도는 근접한 거리에서 다수의 패치가 있는 곳에서 활발하게 일어나고 있어 종의 보전을 위해서는 근접한 거리에 다수의 패치가 필요함을 알 수 있었다. 이번 연구 결과는 붉은점모시나비의 서식지 특성이 분석되어 종 보전을 위한 서식지 디자인 및 설계에 유용하게 사용될 수 있을 것으로 본다. Understanding the ecological complexity and habitat of a species are crucially important to conserve an endangered species. This study evaluated the patch network ecology of the endangered species $Parnassius$ $bremeri$. The results indicated that 188 individuals were captured and 220 were recaptured, respectively. The sex ratio of female: male was 42:146; males were four times more abundant than females. The average longevity of an adult was $3.93{\pm}3.93$ days (male, $4.0{\pm}3.9$; female, $2.5{\pm}1.0$ days); the maximum longevity was 14 days for males and 13 days for females, respectively. Therefore, the expected longevity of males was longer than that of females. The average emigration distance for the species was 377 m, and the maximum emigration distance was 1550 m. The analysis of patch connectivity and individual colonization revealed that the ideal distance between patches was about 300 m. Moreover, a >600 m patch distance decreased the colonization rate severely. We also observed higher immigration and emigration between patches that were clustered in close proximity. This leads us to conclude that a higher number of patches at a close distance is best suited for $P.bremeri$. We find these results to be crucial to determine a policy to protect and conserve this endangered species.

In order to assess the present status of the fragmentation of ecosystem and the building of ecological corridor, 79 EISs(Environment Impact Statements) which were conducted in Kyunggido and Kangwondo have been reviewed using 36 analysing factor. The results obtained from this study were as follows: a. The most frequently appearing type of ecosystem fragmentation was `mountain vs. mountain type in topography` and `2 vs. 2 grades in the degree of green naturality`. b. The most frequently listed fauna in EISs included squirrels and wild rabbits for mammals, grass snake and pit viper for reptiles, and tree frog and true tree frog for amphibians. c. Among the EISs for 50 projects, the construction of ecological corridor mentioned in only 4 projects and other structures such as drainage duct and closed conduit in 14 projects were suggested as ecological corridor. There were no corridors suggested in 32 projects. Thus, in case of using other structures for wildlife animals but ecological corridors, it should be accompanied by incidental facilities for including animal movement.
