RESEARCH PROGRESS OF QUANTITATIVE EVALUATION ON WATER AND SOIL LOSS BY REMOTE SENSING BASED ON GIS

摘要: 水土流失评价研究历经近70年的发展，几经演化，其核心内容就在于定量评价模型及其各参数的算式算法.本文回顾了国内外基于GIS和遥感技术的水土流失模型的发展、演化、各因子的取值算法及其经验值，对其中USLE与CSLE的区别及其因子的取值算法进行了汇总，并指出适用中国实际情况的水土流失方程.

Abstract: The core of water and soil loss evaluation, which has developed and evolved since 1950s, lies in the quantitative models with the formula and algorithm of parameters. This paper reviews the development and evolution of GIS-based remote sensing evaluation models, as well as algorithm for values of each factor and its empirical value, compares USLE and CSLE with their factor algorithms, and finally proposes the equation applicable to China.
