摘要
辽宁省是水土流失严重的省份，通过应用遥感技术，对全省进行了土壤侵蚀普查，现查明全省土壤侵蚀面积为51161km2，占全省总面积的35．7％，同时利用大量小二水库测淤资料及径流小区试验资料，推算出全省不同类型区土壤侵蚀关系模型，并分析辽宁省土壤侵蚀的动态变化情况以及产生这种变化的原因。
Liaoning province is a severe water and soil erosion region in China. Through using tetemetering techniques, the whole province soil erosion has been investigated. The total soil erosion area is more 51 161km2, which is the total soil area of 35. 7%, At the same time, using various test data to calculate the rnodels related to various types of soil and runoff, and the dynamic change situation of soil erosion were analysed here.
