| 摘 要： | 在RS和GIS技术支持下生成的三峡库区2000和2009年土壤侵蚀强度类型图的基础上,运用分形理论分析三峡库区土壤侵蚀的空间格局变化.结果表明:1)在各侵蚀强度类型中,微度侵蚀面积最大且呈显著增加趋势,而其他侵蚀类型的面积均呈减小趋势;2)土壤侵蚀空间格局存在分形特征,近10年间,各侵蚀强度类型的斑块镶嵌结构复杂度变化... |

| Abstract: | 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... |
