Analysis on Soil and Water Losses in Upper Reaches of Beijiang River Basin Based on Remote Sensing
摘要
Abstract
The upper reaches of Beijiang River is a typical region which has serious soil and water losses in southern china,and the sta-tus of soil and water losses in this region need to know with the purpose of providing basic data for soil and water losses preventing and control.The current status of soil and water losses in this region was analyzed based on Alos satellite images of 2007 -2008 in this pa-per,the results show that:the main land use types were forestry and farmland,and the vegetation covers were fine,but the slopes were steep,therefore the area of soil and water losses was more than 2860 km2 ,and the main erosion intensity grade was mild and moderate, and mainly distributed in the mountains and hills of Yizhang county,Linwu county and Lechang county along sides of Wuijiang River basin,and Nanxiong county,Shixing county along sides of Zhenjiang River basin,and Qujiang county and Ruyuan county.关键词
