제2차 전국자연환경조사 지형분야의 성과와 제3차 조사의 특징

Abstract

“Natural Environment Survey” is the law-bound, nationwide-scaled, multidisciplinary project thathas been executed by a government-run institute (National Institute of Environmental Research) since 1988.The purpose of the project is to identify and map the natural resources worthy of conservation, includinglandform, wild plants and animals(birds, amphibia, reptiles, mammals, etc.). The 2nd Natural EnvironmentalSurvey (1997-2004) made it possible to release the first version of National Maps of Ecosystem and Nature in2007, and the 3rd survey has been under way in order to update the information on mapped naturalresources and to identify the new ones for including the next version of National Maps of Ecoystem andNature. This article aims to introduce the main achievement of the 2nd survey and the main direction of the3rd survey from a geomorphological perspective. Through the 2nd Survey, 12,451 geomorphologicalresources have been found around South Korea, and 4,270 of them have been classified as the resourcesnecessary for absolute protection and conservation. The experience of the 2nd Survey also revealed aweakness in the evaluation system of geomorphological resources. The guideline of the 3rd Survey hasreflected such lesson that it has adopted the refined evaluation system of geomorphological resources with acoded item list and a four-class grading. In addition, web-based database has made it possible to reduce the time for data collection and update, which will enhance the effective application of the Map.
