汉江流域荆门段面源污染负荷时空分布与污染现状评价
Spatial Distribution and Evaluation of Non-point Pollution Source in Jingmen Region of Hanjiang Watershed
摘要
Abstract
[Objective] To provide scientific basis for the water pollution control of Hanjiang,the estimation based on the temporal and spatial distribution of non-point source pollution in Jinmen region of Hanjiang watershed was conducted.[Methods] The export coefficient model and the equivalent standard pollution index method were used to illustrate the temporal and spatial distribution and estimated the loads of the nonpoint source pollution in Jinmen region of Hanjiang watershed,including TN,TP,COD and NH3-N.[Results] Rural domestic wastes,livestock breeding,rainfall,land use and urban runoff are the major sources of non-point pollution.Based on the pollution stress,spatial distribution of the pollution source load of different cities was found in the following order:Zhongxiang City＞Shayang County＞Dongbao District＞ Duodao District.The contribution of different pollutant sources had a rank of urban runoff＜rainfall＜land use＜rural domestic wastes＜livestock breeding.[Conclusion] The poor management of pollutants,particularly of the sewage (none or inappropriate treatment),might be the prominent reason of river eutrophication.关键词
