Abstract
The purpose of this paper was to propose a Topographic Position Index(TPI) method for predicting forest wetlands, and also to test the suitability of the predicted forest wetlands by comparing with the existing wetlands in Ulaju-gun and Gyengsangnam-do. A prediction of the spatial distribution of forest wetlands was accomplished by TPI grids from Digital Elevation Model(DEM), and the classification results of slope position and landform categories in study area using the TPI values. According to the results of predicting forest wetlands distribution by TPI method, the predicted area in case of less than
본 연구는 울주군과 경상남도 일대를 대상으로 산지습지 가능지역의 분포를 예측하기 위한 Topographic Position Index(TPI) 방법론을 제시하고, 예측된 분포가능지와 기존 습지의 적합성을 평가하는 것을 목적으로 하였다. 산지습지 분포예측은 DEM에서 추출된 TPI 그리드, 그리고 그 값을 통해 분류된 대상지의 사면 위치와 지형유형에 의해서 수행되어졌다. TPI 방법에 의해 산지습지 분포가능지를 예측한 결과에 따르면, 평탄지 경사기준이
