Variation Characteristics of Soil Erosion in E'zhuang Watershed

This paper takes E’zhuang watershed located in Zichuan water and soil conservation ecological restoration as the study area,uses 3S technique and related soil and water conservation theory and methods comprehensively,studies 1990s’ and 2005s’ soil erosion and dynamic pattern of E’zhuang watershed.The results indicate:Integrated Control benefits of soil erosion increase significantly day by day;The type of soil erosion is water erosion and the mild erosion is the main soil erosion intensity type,moderate and serious erosion exists only in some areas;The relationship between soil erosion and the way of land utilization,vegetation coverage,the slope is close.The research results can provide technical support and determine the reasonable water and soil conservation measures.
