Abstract

Analyzing the condition of soil erosion dynamic changes was conducted in Yangbijiang River basin by means of RS and GIS.The results show that soil erosion has been alleviated with erosion area dropping from 275 867.24 hm2 to 247 282.09 hm2,total erosion modulus decreasing from 1 830.37 t/(km2·a) to 1 729.04 t/(km2·a)and total erosion amount reducing from 7 967 560.11 t to 7 526 463.32 t.The amount of mild erosion and moderate erosion respectively accounts for 75.46% and 75.46% of the total amount in 1990 and 2001.The mild erosion,moderate erosion and grassland erosion control is the core of the handing operation.
