基于RS和USLE的红壤丘陵区小流域水土流失量估算
Estimation of soil erosion in red earth hilly area based on RS and USLE
摘要
Abstract
With Guangheqiao basin in Zixing City of Hunan Province as the study area and by adopting field investigation and sampling,laboratory measurement and analysis,RS techniques and mathematical modeling,the authors calculated each parameter of the universal soil loss equation (USLE) regarding this tributary and estimated the soil erosion.The results show that the value of K parameter (soil erodibility) is between 0.14 to 0.42 t.hm2.h.hm-2.MJ-1.mm-1 with a mean of 0.27 t· hm2.h· hm-2 ·MJ-1 · mm-1 This implies that the soil erodibility is at the medium level.The soil erosion module varies from 0 to 3 817 t.hm-2.a-1 with a mean of 78 t.hm-2.a-1 and the soil loss has reached 292 266 t·a-1.Thus,the soil erosion intensity is high.关键词
