摘要
某河流的污染状况在南方小流域中具有普遍性。本研究通过传统调查分析+卫星遥感监测的技术手段,摸清掌握该河流各主要断面水质污染状况及流域内各类污染源的排放情况,在此基础上对水质污染程度、污染特征及污染成因进行了分析评价。调查表明,该流域水质污染程度与降水量密切相关,生活污水是水体污染的主要来源,治理的关键在于截污,同时要解决一定的补水问题。研究结果可为该流域环境综合整治提供必要的技术支持,研究方法可为今后开展类似小流域污染调查提供可行借鉴。
The water pollution of a certain river is typical in the southern small watershed.In the research,traditional method and satellite remote sensing tenology were used for the river＇s pollution survey,including the water quality,polluters,etc.Based on the suvery,the pollution level,characters and reasons were analysed and evaluated.The research shows that the water pollution is closely related with precipitation,the major pollution comes from municipal sewage and the interception is the key of pollution control.The research result is the technical supports for the river＇s rehabilitation and the reaserch ideas can be borrowed by others similar survy.
