Abstract

Drainage density, defined as the degree to which a landscape is dissected by streams, is a fundamental property of natural terrain that reflect the comprehensive morphologic response of watershed. In this study the spatial variability of drainage density is analyzed by statistical approach to it and its plotting method is proposed. Overland flow length is confirmed to be a highly variable spatial factor from the result of statistical analysis. Distribution map of drainage density based on spatial autocorrelation length in this study would be a superior tool to the classical definition of drainage density.

하천에 의하여 지면이 절개되는 정도로 정의되는 배수밀도는 유역의 형태학적 응답을 포괄적으로 반영하는 자연 지형의 근본적인 특성으로 알려져 있다. 본 연구에서는 배수밀도에 대한 통계학적 접근방법을 기반으로 해당 지형 인자의 공간적 변동성을 분석하고 이로부터 배수밀도의 공간적 변동성을 도시할 수 있는 방법을 제시하였다. 지표면 유하거리의 통계학적 특성을 분석해 본 결과 이 지형인자는 고도의 공간적 변동성으로 대표되는 자연지형의 고유한 특성들 중 하나임을 확인할 수 있었다. 이로부터 본 연구에서 제시한 분포도 형태의 배수밀도는 고전적인 정의의 배수밀도보다 유용한 도구가 될 수 있을 것으로 판단된다.
