摘    要:以黄土高原为研究区,对该区的水土流失进行系统、宏观、综合的分析,确定了一套适于该区水土流失宏观定量评价的指标体系,并运用GIS技术,对该区影响水土流失的各个因素进行空间分析,实现了多源数据的空间集成和专题信息的提取,建立了适于该区水土流失评价的宏观定量数学模型,并对研究区一定评价年限内的水土流失状况进行了应用评价。

关 键 词:GIS  区域水土流失  数学模型  定量评价  黄土高原

Abstract:In this project the soil and water loss of the sample region, the Loess Plateau of China has been studied systematically, synthetically and macroscopically; series of quantitative indices have been set up to assess the soil and water loss of this region; GIS is used to analyze the factors of soil and water loss spatially, to aggregate the data with difFerent origins and to extract the thematic information; the mathematical model is set up to assess the regional soil loss and finally some application results have been got.
Keywords:GIS  Regional soil and water loss  Mathematical model  Quantitative assessment  the Loess Plateau in China
