본 연구는 서울시 도심 하천 중 국가하천인 중랑천을 대상으로 보전지역 설정 프로그램인 Marxan with zones 프로그램을 기반으로 한 하천 내 보전지역 설정 및 생태적 관리방안을 제시하였다. Marxan with zones 프로그램 적용은 유역권(planning unit) 설정, 맵핑지표(mapping index) 적용, 반복적인 분석을 위한 수치보정, 분석을 통한 시나리오 별 최적안 작성, 시나리오 별 민감도 분석, 시나리오 중 최적안 검토 및 선정 단계로 진행하였다. 중랑천 내 보전지역 설정 결과, 기존에 보전지역으로 지정 및 관리하고 있는 중랑천 상류 야생생물보호구역을 포함한 다수의 유역권과 중랑천 하류의 철새보호구역을 포함한 유역권이 핵심보전지역으로 설정되었다. 상류는 중랑천을 중심으로 수락산과 도봉산 등 산림이 인접하여 다수의 야생조류가 관찰되었다. 하류는 한강 합수부, 청계천 합수부 등 하천생태계가 인접하여 하천을 따라 이동하는 철새 도래지이다. 따라서 중랑천 상류와 하류는 유역권 내 도봉산, 수락산, 응봉산 등 산림생태계, 도심 내 녹지, 청계천 합수부, 한강 합수부 등 다양한 생태계와 연결되어 있어 보전지역 설정에 영향을 주었다. 본 연구는 보전지역 검증 시 Marxan with zones 프로그램을 통한 기존 보전지역 설정 및 평가를 검증하였고, 프로그램을 통해 핵심보전지역으로 도출된 유역권을 생태적으로 관리하기 위해 하천 내 관리방안과 유역권 관리방안으로 구분하여 제시하였다. This study presented a plan for the establishment of conservation areas and the ecological management of those areas in the stream based on the Marxan with Zones Program for a Jungrangcheon Stream in downtown Seoul. The application of the Marxan with Zones Program included the stage of planning unit setting, application of mapping indices, numerical correction for repetitive analysis, creation of scenario-specific optimizations through analysis, analysis of sensitivity by scenario, review, and the selection of optimal plans among the scenarios considered. As a result of the establishment of a conservation area near Jungrangcheon Stream, which has several watershed areas, including an upper-middle-class wildlife protection zone, which was previously designated and managed as a conservation area, and the migratory protection zone downstream of Jungrangcheon Stream were designated as key conservation areas. A number of wild birds were observed in the upper reaches of Jungrangcheon Stream, adjacent to the forests of Suraksan Mountain and Dobongsan Mountain. The downstream area is a habitat for migratory birds that travel along the stream and the adjacent river ecosystem, including the Hangang River confluence and Cheonggyecheon Stream confluence. Therefore, the upper and lower reaches of Jungrangcheon Stream are connected to forest ecosystems such as Dobongsan Mountain, Suraksan Mountain, and Eungbongsan Mountain, as well as urban green area and river ecosystems in the basin area, which influence the establishment of conservation areas. This study verified the establishment and evaluation of existing conservation areas through the Marxan with Zones Program during the verification of the conservation areas and was presented as in-stream management and basin management method to manage the basin areas derived from core conservation areas determined through the program.

본 연구는 경기도 김포의 최서북단 DMZ 접경지역 및 민북지역에 위치한 문수산의 산림유전자원보호구역 일대의 관속식물상과 침입외래식물 등을 파악하고 확인된 식물들의 효율적인관리와 생물다양성 보전을 위한 기초자료로 활용하기 위하여실시하였다. 조사는 2019년 4월부터 2020년 10월까지 총 17회에 걸쳐 실시되었다. 문수산 산림유전자원보호구역 일대의 관속식물상은 총 95과 276속 395종 13아종 33변종 3품종 444분류군이 분포하는 것으로 확인되었다. 이는 우리나라 관속식물 총4,881분류군의 약 9.09%로 나타났다. 문수산 산림유전자원보호구역에서 출현한 한반도 특산식물은 은사시나무, 오동나무, 산이스라지, 백운산운추리 등 6종이 관찰되었다. IUCN 지정 희귀식물은 총 3분류군이 관찰되었다. 위기종(EN)은 복사앵도나무, 약관심종은 쥐방울덩굴과 창포가 출현하였다. 식물구계학적 특정식물은 초 39분류군으로 파악되었다. IV등급은 바위말발도리 등 2분류군, III등급은 고광나무, 병아리꽃나무 등 8분류군이 확인되었다. II등급은 잣나무 및 오리나무 등 총 10분류군이 관찰되었다. 조사지역에서 출현한 침입외래식물은 개망초 , 달맞이꽃 및 개쑥갓 등 58분류군으로 확인되었다. 귀화율은 13.1%로 나타났으며, 도시화지수는 18.0%로 계산되었다. 본연구에서 파악된 문수산 산림유전자원보호구역의 관속식물상과 선행연구와 비교한 결과, 최근 조사 구간이 더 넓고 다양한경로를 조사했음에도 불구하고 선행연구에 비해 분류군 수가감소한 것으로 파악되었다. 특히 희귀·특산식물의 수는 크게감소하고 외래침입식물의 수는 임도 및 등산로 등으로 크게 확산한 것으로 확인되었다. 따라서 산림유전자원보호구역 내 자생식물의 보전 및 관리를 위해 산림휴식년제 등을 도입해야 할것으로 생각된다. This study was investigated to find out the distribution of vascular flora and remarkable plants and its factors and management plan in the forest genetic resource reserve of Mt. Munsu, located in the DMZ and DMZ border area in Gimpo, Gyeonggi-do province. The survey was carried out 17 times from April 2019 to October 2020. First of all, in the forest genetic resource reserve of the Mt. Munsu, a total of 444 taxa in 95 families, 276 genera, 395 species, 13 subspecies, 33 varieties and 3 forms. This result was found to be about 9.09% of the total 4,881 taxa of vascular plants in Korea. In addition, endemic plants were classified as 6 taxa. Floristic special and rare plants were identified as 39 taxa and 3 taxa, respectively. Lastly, the invasive alien plants that appeared in Mt. Munsu of the forest genetic resource reserve were observed in 58 taxa. Moreover, the naturalization rate was 13.1% and the urbanization index was calculated to be 18.0%. As a result of comparing the vascular flora at the forest genetic resource reserve on Mt. Munsu identified in this study with previous studies, it was found the number of taxa was decreased compared to the previous studies, despite the fact that the recent survey section was wider and more varies routes were investigated. In particular, it was confirmed that the number of rare and endemic plants decreased significantly, and the number of invasive plants greatly spread to forest roads and hiking trails. Therefore, it is considered that the forest rest year system should be introduced for the conservation and management of native plants in the forest genetic resource reserve.

This study was conducted to predict the distribution of rare·endemic plants (Sophora koreensis Nakai) in the border forests where wildfire damage occurred and to quantify the damage. For this purpose, we tried to derive more accurate results through forest area damage (NBR) according to the Burn severity of wildfires, damage by tree species type (Vegetation map), and MaxEnt model. For Burn severity analysis, satellite imagery (Landsat-8) was used to analyze Burn severity (ΔNBR2016-2015) and to derive the extent of damage. To prepare the Vegetation map, the land cover map prepared by the Ministry of Environment, the Vegetation map prepared by the Korea Forest Service, and the vegetation survey conducted by itself were conducted to prepare the clinical map before and after the forest fire. Lastly, for MaxEnt model analysis, the AUC value was derived by using the habitat coordinates of Sophora koreensis Nakai based on the related literature and self-report data. As a result of combining the Maxent model analysis data with the Burn severity data, it was confirmed that 45.9% of the 44,760 ㎡ of habitat (predicted) area of Sophora koreensis Nakai in the wildfire damaged area or 20,552 ㎡, was damaged.
