| Abstract: | This paper deals with the dynamic change and regularity of evolution for soil ero-sion in Xingguo county ,Jiangxi province by remote sensingimages of different periods. The results indicate that the area of soil and water losses in 1958,1975 nad 1988 is 2006. 19 km2,2111. 61 km2 and 1623. 24 km2,and an amount of soil erosion is 10661900 tons,10429800 tons and 6072100 tons respectively in Xingguo county. From 1958 to 1988,A total of decreases in soil and water losses area in the grades of deep erosion and more is 430; 64 km2;forest area becomes form 514. 78 km2 to 1359. 19 km2,and bare area becomes from 460. 94 km1 to 105. 81 km2. |
