Abstract��

Taking Zhayu town of Zuogong country in Changdu City as study area��and using CBE��S-2 remote sensing images��digital elevation model data and land use type data��the authors extract vegetation index and densi- ty slice and determine vegetation coverage and classify it by the software of remote sensing��extract slope information and classify it by the software of geographic information system��and revise existing land use types under the scale of 1�� 500 00�� The results show 76. 26% of the soils in Zhayu town at a mild and below erosion state��strong and above soil erosion reach to 5. 48%�� The area of severe soil erosion mainly located at the cultivated land��middle soil ero- sion area mainly located at grassland�� Therefore��rationalization of land utilize��the increase of the vegetation cov- erage and its related measure could reduce soil erosion intensity effectively��
