【摘要】 随着城市的发展，城市水环境的污染已经引起人们的关注，但目前对水污染的控制主要着重于点源污染，对城市降雨径流所带来的面源污染的研究和控制还非常薄弱。本文以南昌大学前湖校区为研究区域，通过选取其不同下垫面类型(路面和草坪)的代表区，对若干场次的降雨径流水质进行监测采样，并选取两场较完整的降雨过程，研究测试结果。结合降雨过程资料，分析降雨径流的产流、产污特性，以及径流对受纳水体—前湖校区龙腾湖和丰收水库的水质影响。分析测试了径流水中主要污染物的种类和浓度范围，各种水质指标的相关关系，并对降雨径流的可生化性进行了分析研究。结合国外研究资料，探讨了土地利用方式、降雨状况、路面沉积物性质等因素对径流污染物浓度的影响，分析了公路路面径流中污染物的排放规律以及冲刷模型的适用性。经过理论分析，认为污染负荷法和数学模型计算法是研究路面径流对受纳水体水质影响的有效方法。总结国外研究资料，指出校园环境管理、路面清扫、制定条例和规定等非工程措施和植被控制、湿式滞留池、渗滤系统、湿地等工程措施的合理选用和适当结合是有效的控制径流污染的径流管理控制措施。本研究可对南昌大学建设生态校园；对南昌市环境管理部门搞好环境保护和环境规划、作好校园建设项目对水环境的影响评价、控制非点源污染提供一些基础性的资料和依据。更多还原

【Abstract】 With the development of urbanization of our country, water pollution of city hasbeen widely concerned.Now,we have much more experience in point pollutioncontrol,but the study and control of urban Non-point source pollution,which is takenfrom storm water runoff is still very poor.In this article,results of a series of water quality monitoring of rainfall runoff atthe experimental area of nanchang univercity qianhu campus were analyzedcombining corresponding rainfall data.Result indicated the flow-yield andpollutant-discharge characteristic of runoff water quality.Combined with someoverseas studies,the correlations of discharged pollutant load to runoff-precipitationhave also been studied .Through careful analysis it has been accepted that annnualpollutant load method and mathematics model method are two useful ways to studythe impact of runoff on receiving water bodies. It also provide some effective runoffmanagement methods such as environment management in campus, road cleaning,vegatation control, wet detention pond, infiltration system and wetland.These study restults can provide some fundamental material and methods toenvironmental administrared department in order to control non-point sourcepollution and protect our environment more effectively.更多还原
