摘 要：
[目的]用中国土壤流失方程(CSLE模型)对区域土壤侵蚀定量计算的方法进行初步探索,以期提高土壤侵蚀监测精度,有效、客观地反映水土流失治理效果。[方法]采用CSLE模型、遥感解译与统计分析相结合的方法,对准格尔旗境内的皇甫川流域进行土壤侵蚀定量评价。[结果]研究区2015年侵蚀总量1.38×10~7 t,年均侵蚀模数4 920.23t/(km~2·a)。土壤侵蚀强度以中度为主,轻度和强烈次之。[结论]用CSLE模型进行土壤侵蚀定量分析,综合考虑了降雨、土壤、植被、地形、措施等多项因子,可用于区域土壤侵蚀定量研究。

摘 要：
[Objective]Based on the Chinese soil loss equation(CSLE),this study aims to explore the method to quantitatively calculate soil erosion and improve the accuracy of soil erosion monitoring and reflect the effect of soil and water conservation effectively and objectively.[Methods]By using the CSLE model,the remote sensing interpretation and the statistical analysis,we quantitatively assessed the soil erosion in the overlapping area of the Zhungeer Banner and Huangfuchuan river basin.[Results]The total erosion in the study area was 13.778 3 million tons in 2015,and the annual erosion modulus was 4 920.23 t/(km~2·a).The erosion was mainly moderate erosion,mild erosion and strong erosion are followed.[Conclusion]The soil erosion was quantitatively analyzed with CSLE model,and several factors such as rainfall,soil,vegetation,topography and measures were considered,which could be used for quantitative study of soil erosion.
