Abstract

Verifying about eligibility of targeted site is necessary for execute Afforestation and Reforestation Clean Development Mechanism (A/R CDM) project which is followed by system of Kyoto protocol. The site have to be identified by which could not be in conformity with definition of forest. This study tried to propose a technology of classify for site selection of A/R CDM. We chose several parts of Yangpyeng as study area and applied LiDAR data and remotely sensed imagery for considering about tree height, degree of crown closure, and land area which 3 factors for identify forest. LiDAR data was used for offset the shortage of remotely sensed imagery that cannot perfectly determine the forest definition due to absence of 3-dimentional information, but can be obtained from LiDAR. Considering tree height, degree of crown closure, and land area simultaneously by moving window, classified fields to forest and non forest based on pixel size. As a result, 124.06 ha for suitable to doing plantation and approximately 357.02 ha are in negative. Technology that applied for analyzing will provide fundamental methodology not only site selection for A/R CDM, but will be utilized in other Kyoto protocol.

교토메커니즘의 체제하에서 신규조림 및 재조림(Afforestation and Reforestation Clean Development Mechanism, A/R CDM) 사업을 위해서는 대상지적격성 입증이 필요하다. 대상지 적격성 입증을 위해서는 과거에서 현재까지 산림이 아닌 지역으로 규정되어 있으므로 현재 대상지역이 산림 정의에 부합되지 않음을 입증하여야 된다. 본 연구에서는 위성영상을 이용하여 A/R CDM 대상지를 선정을 위한 분류기법을 제시하고자 한다. 연구대상지는 양평군 양평읍의 일부 지역을 선정하였고, 산림정의에 부합하는 3가지 요소 즉, 수고, 울폐도, 면적을 고려하여 LiDAR 자료와 항공사진을 이용하였다. Moving window를 적용하여 수고, 토지면적, 울폐도를 동시에 고려하여 화소기반 산림/비산림 지역으로 분류하였다. 그 결과, 조림 가능지역은 124.06 ha이고 조림 불가지역은 약 357.02 ha이다. 분석에서 적용된 기법은 A/R CDM 사업 대상지 선정 뿐만아니라 기타 교토메커니즘의 활용에 기초방법론을 제공하였다.
