Spatial pattern variation of soil erosion in Three Gorges Reservoir Area based on fractal theory
基于分形理论的三峡库区土壤侵蚀空间格局变化

Using RS and GIS technology,the distribution of soil erosion intensity in Three Gorges Reservoir Area was revealed in 2000 and 2009 respectively.The variation of spatial pattern of soil erosion were analyzed by using fractal theory.The results showed that: 1) The area of slight erosion was the largest in the study area with a significant increase from 2000 to 2009,vice versa with a decrease in other erosion grades;2) The spatial pattern of soil erosion in this area showed fractal characteristics.The complex...
