摘要
立足南水北调中线水源区独特的地理概况和水土流失的特征,利用GIS对空间数据处理和数值分析方法来估算当地的土壤侵蚀量.确定研究区域内土壤侵蚀量的各种不同等级,最终达到对水源区水土流失估算的目的,为南水北调中线工程水源区水土保持提供较为可靠的信息资源.
Based on the geography survey and the traits of soil erosion of south-to-north water diversion center line water source reserve,the article makes use of GIS to deal with spacial data and data analysis in order to evaluate local soil erosion situation,and make sure different classifications of it and at the end reach the aim of evaluating the water source reserve situation.To provide reliable information source for protecting the water source reserve of south-to-north water diversion center line.
