| 摘 要： | 在地理信息系统(GIS)和遥感(RS)技术的支持下,采用通用土壤流失方程(Universal Soil Loss Equation,USLE),综合考虑影响水土流失的自然因素和人为因素,进行了江苏省太湖流域水土流失的定量评价。研究结果表明:江苏省太湖流域水土流失以微度流失为主,而强度及其以上流失主要发生在西南部丘陵地区,东部太湖平原区有零星分布。

| Abstract: | With the support of GIS and RS,through synthesizing the natural and artificial factors,the water and soil loss of Taihu basin in Jiangsu province was quantitatively evaluated by Universal Soil Loss Equation(USLE).The results showed the grade of water and soil loss of Taihu basin mainly belonged to tiny-degree,whereas the intense-degree was found only in the south-western hilly area and scatteredly in the eastern plain area. |
