Title: Study on Spatial Relationship of Land Use and Soil Erosion of Different Regions
Abstract: The paper introduces and amends the composite indexes of soil erosion intensity and regional soil erosion intensity and conducts quantitative analysis on spatial relationship of types of land use and soil erosion intensity of whole China territory,the middle and lower areas of Liaohe River,headwater area of Danjiangkou Reservoir of South-North Water Transfer Project of Hubei part and 4 regions of Huidong County in Guangdong based on sum up of general study methods of spatial relationship of land use and soil erosion.The outcomes show that the sequence of soil erosion of types of land use in different regions is different and the sequence of soil erosion of types of land use in different periods of the same regions is uncertainty;the occurred rate of soil erosion of new wasteland is higher than that of idle wasteland for years;the occurred rate of soil erosion of grassland is higher;the occurred rate of soil erosion of non-irrigated farmland is high and the soil erosion intensity of land used for construction is great during construction and becomes smaller after completion.
