| 摘 要： | 通过GIS软件的水文分析模块对浙江省长兴县30mDEM数据做流域划分，选择最北部的一个完整的小流域作为研究区，以氨氮作为污染指标，利用改进后的输出系数法合理估算其非点源污染负荷及主要来源，并结合行政区划和各乡镇特点提出相应的非点源污染控制手段，为当地可持续发展及相关决策提供参考．

| Abstract: | Using the hydrological analysis module of GIS to divide watershed based on the data of 30-meter DEM of the county of Changxing in Zhejiang province and selecting the most northern part which is a complete watershed as the study area as well as with ammonia nitrogen as a pollution assessment index, we use an improved export coefficient method for estimating polluting load of non-point source pollution and analyze its main source, and then make the appropriate means of non-point source pollution control combined with characteristics of admin- istrative divisions and towns. The results of the study will offer some references for the local decision-making and sustainable development. |
