Abstract

Currently, Korea is ahead of the forest sector such as forest management, forest investigation and forest management, which is not insufficient compared with the forest advanced countries (Germany, Japan, Austria). However, there is a lack of systematic and advanced forest management plan and related research, and it is not enough to construct GIS for practical and complex analysis. Therefore, in order to perform forest analysis effectively, this study maps forest basic statistics (2010, 2015) based on GIS to map forest information. As a result, the forest area, growing stock, average growing stock, and forest rate could be produced with the maximized visual effect by detailed administrative districts, and systematic analysis of the time series changes was also possible. Forest area increased only in Goseong, Sejong, Cheolwon, Yeoncheon, Daejeon, and Seoul Guro-gu, and decreased in all other areas, while growing stock increased in most areas, Uljin, Ulleung, Seoul Nowon-gu, and Seoul Gangdong-gu. The average growing stock was found to increase in most areas excluding the four administrative districts and the forest rate was higher in 10 regions (Goseong, Yeoncheon, Gongju, Busan Dong-gu, Daegu Seo-gu, etc.) but it decreased in most regions excluding 10 regions. Based on this research, we plan to produce and analyze forest information maps for smaller administrative districts and more.

현재 우리나라는 산림선진국(독일, 일본, 오스트리아 등)과 비교해도 부족하지 않을 만큼 산림경영, 산림조사 및 산림관리 등 산림분야에서 앞서 나가고 있는 상황이다. 그러나 체계적이며, 고도화된 산림관리 방안 수립 및 관련 연구는 부족하고, 실질적이면서 복합적인 분석을 위한 GIS로의 구축도 미흡한 상황이다. 이에 본 연구에서는 산림분석을 효율적으로 수행하기 위해 GIS를 기반으로 산림기본통계자료(2010년, 2015년)를 지도화하여 산림정보지도를 제작하였다. 그 결과 세부 행정구역별 산림면적, 임목축적, 평균임목축적, 산림률을 시각적 효과가 극대화된 지도로 제작할 수 있었으며, 시계열적인 변화 또한 체계적으로 분석할 수 있었다. 산림면적은 고성군, 세종특별시, 철원군, 연천군, 대전광역시 동구, 서울특별시 구로구에서만 증가하고, 그 이외 지역에서는 모두 감소하는 것을 알 수 있었으며, 임목축적은 대부분 지역에서 증가한 반면, 2011년 산불피해를 입은 울진군을 비롯하여 울릉군, 서울특별시 노원구, 서울특별시 강동구, 서울특별시 중구에서만 감소하는 것을 알 수 있었다. 평균임목축적은 4개 행정구역을 제외한 대부분의 지역에서 증가하는 것을 알 수 있었으며, 산림률의 경우 고성군, 연천군, 공주시, 부산광역시 동구, 대구광역시 서구 등 10개 지역을 제외한 대부분의 지역에서 감소한 것을 알 수 있었다. 향후, 본 연구를 바탕으로 보다 소규모의 행정구역과 더 많은 시기를 대상으로 산림정보지도를 제작하고 분석을 진행할 예정이다.
