Temporal and spatial variability of soil erosion in Dongbeigou Watershed in northern mountainous area,Hebei Province,based on Land Use/Cover Change(LUCC)
基于LUCC的冀北土石山区东北沟流域土壤侵蚀时空变化分析

Land-use has a direct effect on the change of soil erosion intensity through changing vegetation cover,soil property and runoff velocity.The Dongbeigou Watershed with an area of 19.34 km2 was chosen as the study area.Based on climate,vegetation coverage,soil,land-use survey and Quickbird image data in 1990 and 2009,the change characteristics of land-use and soil erosion were revealed by means of the shift matrix of land-use and Revised Universal Soil Loss Equation(RUSLE) supported by GIS.The results showed:...
