Analysis on the Influencing Factors and Comprehensive Management of Environmental Problems in Dongping Lake

[Objective]We aimed to study the influencing factors and comprehensive management of environmental problems in Dongping Lake.[Method]Based on field investigation and historical data,environmental problems of Dongping Lake and their influencing factors were analyzed,and seven measures about comprehensive management of environmental issues and ecological protection of Dongping Lake were put forward.[Result]During recent years,the content of total nitrogen and total phosphorus in Dongping Lake showed a decreasing trend,but the water was still in the eutrophic state.The environmental problems of Dongping Lake,like flood,drought and pollution,are closely linked to natural and man-made factors,such as regional seasonal precipitation,industrial and agricultural pollution,etc.In order to control the environmental problems of Dongping Lake,we should strengthen the construction and management of wetland nature reserves,develop ecological agriculture,establish an integral system for environmental monitoring and information management,reinforce propaganda and education to improve residents’ environmental consciousness,etc.[Conclusion]The research could provide scientific references for the comprehensive management of environmental problems in Dongping Lake and its basin.
