摘 要：
[目的]对四川省凉山地区土壤水力侵蚀状况进行定量研究,为该区水土流失调查提供数据支持。[方法]利用四川省地理国情普查数据,基于对USLE模型的本土化研究成果进行分析和研究。[结果]凉山彝族自治州平均土壤侵蚀模数为1 207.67t/(km2·a),土壤侵蚀面积为15 221km2,占该区土地总面积的25.19%。从空间分布上看其中金沙江沿岸是凉山彝族自治州土壤侵蚀最为严重的地区,其次是安宁河流域和黑水河流域。[结论]凉山州目前水土流失面积较大,水土流失治理的形势依然严峻。

摘 要：
[Objective]The quantitative study of soil hydraulic erosion in Liangshan area of Sichuan Province was conducted to provide data support for the investigation of soil erosion in this area.[Methods]Data of geographic conditions in Sichuan Province were obtained from previous provincial investigation and then processed based on the localization research of USLE model.[Results]Annual average amount of soil erosion in Liangshan Region is 1 207.67t/(km2·a).Soil erosion area is 15 221km2,accounting for 25.19% of this area.Area around Jinsha River is the most serious soil erosion areas,followed by Anning River basin and Heishui River basin.[Conclusion]Soil erosion area is still large,and the situation of soil erosion is still grim in this place.
