| 摘 要： | 根据于桥水库周边流域非点源污染的特点,在充分考虑污染源与水库的距离以及库体自净作用因子的基础上,对饮用水源地非点源敏感区划分的通用土壤流失方程（USLE）方法进行了改进。结合2009年库区周边的ETM遥感影像、数字高程模型（DEM）和土地利用类型等数据,应用改进的USLE模型对库区周边非点源污染敏感区划分进行了实证研究。研究结果表明,库区西部的敏感性明显高于东部,库周的别山镇、五百户镇、渔阳镇、穿芳峪乡和马伸桥镇的水库沿岸是非点源污染敏感度较高的区域,是非点源污染的优先控制区。

| Abstract: | According to the non-point source(NPS) pollution characteristics of Yuqiao Reservoir,the Universal Soil Loss Equation(USLE) was modified for identificating the sensitive areas for NPS pollution control.As two important factors,the distance from the pollution source to the reservoir and self-purification of the reservoir were introduced in the USLE model.Based on the data of ETM image,Digital Elevation Model(DEM),land use and soil type,the modified model was used to differentiate sensitivity zones for NPS po... |
