| 摘 要： | 在GIS技术支持下,利用遥感影像解译资料、数字高程模型(DEM)及土壤、降雨等数据,对修正通用土壤流失方程RUSLE中各因子进行了量化分析,进而实现南水北调东线工程江苏段沿线区域土壤侵蚀量估算,并根据估算结果进行土壤侵蚀强度分级,揭示沿线区域水土流失空间分布特征。结果表明:江苏段沿线区域2000年和2005年微度土壤侵蚀等级面积均占研究区总面积的95%以上,强度侵蚀及以上等级面积所占比例很小,主要分布在盱眙县、邳州市和铜山县部分地区。

| Abstract: | The factors in the Revised Universal Soil Loss Equation(RUSLE) were quantitatively analyzed by using the data of remote sensing image interpretation,digital elevation model(DEM),soil,rainfall and so on based on GIS technology.According to the results of quantitative analysis,the amount of soil erosion along the east route of South-to-North Water Transfer Project in Jiangsu province was estimated to classify the intensity of soil erosion.Then the spatial distributive characteristics of soil erosion were reve... |
