Abstract

In order to conserve soil functions to the highest degree in development projects, it is necessary to identify and manage specific area (so called soil management area) including soils with good or excellent functions. Therefore, in this work, we conducted a preliminary study how to identify soil management area in environmental impact assessment on development projects. To do this, quantitative evaluation was carried out on two example projects, using InVEST model considering a couple of soil functions, i.e., erosion control and carbon sequestration functions. Then, soil management area was identified through overlay analysis. The methodology developed in this study is able to be used widely for more detailed analysis with high resolution and furthermore overlay anaysis with other assessment items. For more perfect assessment, other soil fuctions needed to be taken into account into our methodology.

개발사업 예정지역에서 토양의 본래 기능을 최대한 보전하기 위해 토양을 중점적으로 관리하는 지역(토양중점관리지역)을 선정하여 관리할 필요가 있다. 이에 본 연구에서는 개발사업 환경영향평가시 어떻게 토양중점관리지역을 선정할 것인지에 대한 예비연구를 수행하였다. 토양 기능중 토양침식조절기능과 토양탄소저장기능을 우선적으로 고려하여 InVEST 모형을 활용한 정량적 평가를 수행하였고 중첩분석을 통해 2개의 개발사업 사례에 대해 토양중점관리지역을 선정하였다. 본 연구를 통해 개발된 방법론은 고해상도의 정밀한 분석, 다른 평가항목들과의 중첩분석 등 다양하게 활용할 수 있다. 좀 더 완벽한 평가를 위해 토양의 다양한 기능을 포함한 평가방법론을 개발할 필요가 있다.
