摘要: 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。

关键词: 川中丘陵区, 土壤侵蚀强度, 泥沙输移比

Abstract: Using USLE model and GIS techniques, this paper estimates the soil loss amount and gives the erosion rate distribution at the Lizixi basin. The results indicate that Lizixi basin is mainly occupied by mild erosion, and large discrepancies exist between soil erosion rates by different methods.

Key words: Sichuan hilly region, soil erosion rate, sediment delivery ratio
