초록
본 연구에서는 기존의 지위지수 추정식의 문제점을 보완하기 위해 수치 산림입지도에서 추출한 28개 입지환경 인자 중에서 몇 가지 인자만으로 구성된 최적의 조합에 의해 지역별 주요수종에 대한 지위지수 추정식을 개발하고자 하였다. 본 연구결과에서 도출된 지위지수 추정식에서 채택된 수종별 입지환경 인자는
This study was conducted to develop regional site index equations for main tree species in Gangwon, Gyunggi-Chungcheong, Gyungsang, and Jeolla area of Korea, using environmental and soil factors obtained from a digital forest site map. Using the large data set obtained from the digital forest map, a total of 28 environmental and soil factors were regressed on site index by tree species for developing the best site index equations for each of the regions. The selected main tree species were Larix 1eptolepis, Pinus koraiensis, Pinus densiflora, Pinus thunbergii, and Quercus acutissima. Finally, four to five environmental and soil factors by species were chosen as independent variables in defining the best regional site index equations with the highest coefficients of determination
