采用USLE模型与GIS技术相结合的方法,估算了川中丘陵区李子溪流域的土壤侵蚀总量以及侵蚀强度空间分布。结果表明李子溪流域主要以微度侵蚀为主,且不同的方法得到的侵蚀强度存在着较大差异。
Using the method of combining USLE model and GIS technology, the total soil erosion and the spatial distribution of erosion intensity in Lizi River Basin in central Sichuan Basin were estimated. The results show that the Lizi River Basin is mainly dominated by micro-erosion, and the erosion intensity obtained by different methods is quite different.
