摘要
应用修正过的土壤流失方程(USLE),在GIS技术的支持下,确定了淮北地区的降雨因子、土壤侵蚀因子、植被覆盖因子、水土保持因子和坡度坡长因子,估算了这一地区的水土流失模数,评价了区域内土壤侵蚀分布特征,以期为本区水土保持布局提供理论支持。
With the technical support of GIS,the rainfall factor,soil erosion factor, vegetation coverage factor,soil and water conservation factor, slope and length factor of the Huaibei area were accurately estimated. Then, a revised USLE equation was used to calculate the soil erosion modulus and evaluate the regional distribution of soil erosion. The research could provide the theoretical support for soil and water conservation of in the Huaibei Area.
