摘要
从土壤侵蚀的环境背景入手,划分了关中中东部地区的土壤侵蚀类型。以侵蚀类型为单元,依据侵蚀因子与侵蚀强度的关系建立了侵蚀强度评判模式,进而利用流域输沙模数对评判结果进行了检验,符合区域土壤侵蚀评判的精度要求。最后总结了侵蚀强度分布规律。
Beginning with the evironment background of soil erosion, the types of soil erosion was classified in the middle and east part of Guanzhong area. According to the ralations between soil erosion factors and soil erosion intensity, the soil erosion evaluation model was set up. Then, the evaluation result was tested with sediment transport quantity of basins. At last, the distribution of erosion intensity was summed up.
