| 摘 要： | 重庆市位于长江上游生态屏障的最前沿，其水土流失对整个长江流域生态安全和三峡水利枢纽工程的安全运行有着重要影响。依据1999年重庆市水土流失遥感调查结合水土流失观测资料，评价了重庆市土壤侵蚀强度及区域分布。根据USLE方程中5N因子对土壤侵蚀敏感性影响，建立了土壤侵蚀敏感性评价指标体系，对重庆市土壤侵蚀敏感性进行评价。结合GIS技术，分析了重庆市土壤侵蚀敏感性的空间分布，探讨了土壤侵蚀的敏感性原因，并提出了有关水土保持对策。

| Abstract: | The eco-environment of the Yangtze River and Three Gorges reservoir area is severely impacted by serious soil erosion in Chongqing City. Using 1999 remote sensing information, soil erosion characteristics have been assessed and analyzed. Indices for soil erosion sensitivity evaluation have been developed, guided by five factors in the Universal Soil Loss Equation(USLE). The indices for soil erosion sensitivity are defined as none, mild, moderate and high. Also, the spatial characteristic of soil erosion sensitivity has been defined using a geographical information system(GIS). Methods for soil erosion control are discussed to promote sustainable development in the area of the Three Gorges reservoir. |
