Pollution Sources and Control Countermeasures of Non-Point Sources of Wuli Lake,Lake Taihu

NIAN Yue-gang~1,LI Ying-Jie~(2),SONG Ying-wei~(3,4),NIE Zhi-dan~1, SUN Yan-ni~11.Research Center for Lake Eco_environment,Chinese Research Academy of Environmental Sciences,Beijing 100012,China2.College of Resources and Safety Engineering,China University of Mining & Technology,Beijing 100083,China3.Department of Environmental Sciences,East China Normal University,Shanghai 200062,China4.Beijing Municipal Research Institue of Environmental Protection,Beijing 100037,China  
Based on field survey,it is identified that the non-point sources of Wuli Lake are from urban roads,residential areas,agriculture,and fertilization of greensward.The pollutants flow into lake through rivers,lakeshore and atmosphere precipitation during raining.According to characteristics of environment,the watershed is divided into 3 pollution control zones: landscape tourism management zone of southwest mountain(A),pollution control zone of north New City Zone(B) and comprehensive improvement zone of southeast agriculture and fishery(C).The pollution control strategies of non-point sources was suggested that the protection of terricolous vegetation and restoration of riparian vegetation was suitable for zone A,the reconstruction of riparian,estuarine and riverway vegetation and the applying of constructed wetlands was suitable for zone B,and the engineering of organic agriculture,sewage treatment,stabilization lagoon and riverway ecological purification was suitable for zone C.
