贵州高原水土流失及其影响因素研究

Soil Erosion and Its Affective Factors in Guizhou Upland

在利用遥感技术编制贵州省土壤侵蚀图的基础上，阐述了贵州省不同级别水土流失强度分布状况、水土流失潜在危险程度及水土流失强度分区；分析了贵州高原水土流失产生的自然背景与影响因素；并根据贵州高原的特点提出了治理保护的战略措施。

On the basis of compiling the soil erosion map of Guizhou upland by using remote sensing technique, the natural background and factors affecting soil erosion in Guizhou upland are analyzed. The different grades of soil erosion and the potential dangerous degrees are divided and their distribution are discussed. Then the strategic measures to controll soil erosion and to protect the ecological environment have been put forward: (1) To make the completed plan and comprehensive controll; (2) To controll soil erosing according to different region and different types; (3) To combine the economic and the ecological benefits, and pay attention to the coordinated development of the population, resources, environment and economy; (4) to establish the dynamic supervised organization on soil erosion and conservation by using GIS and RS methods.
