- Abstract:
-
Taking center Sichuan Province as a case study, we used the database from the completed report for its fifth erosion protection project and divided the study area into various small watersheds using cluster analysis in terms of the area proportion for different land-uses. Then we quantified the relationship between soil erosion (dependent variable) and land-use area (explanatory variable) by multiple linear regression analysis. We also analyzed the differences in soil erosion features and land-use patterns among various small watersheds in the study area. The results show that there are four categories of small watersheds according to land-use patterns, and the sources and rate of soil erosion are significantly defferent among these small watersheds.
