Title: Study on the Control Countermeasures of Agricultural Non-point Source Pollution in Lakeside Belt of Poyang Lake
Abstract: [Objective] The aim was to study the control countermeasures of agricultural non-point source pollution in lakeside belt of Poyang Lake.[Method] The current situation of water quality in Poyang Lake was analyzed firstly,and then the causes of agricultural non-point source pollution in Duchang section of Poyang Lake were studied,finally corresponding control countermeasures were put forward.[Result] Agricultural non-point source pollution in Duchang section of Poyang Lake was mainly related to the rapid development of pearl industry and livestock industry,aggravated soil erosion and excessive utilization of fertilizer.Based on analysis of current environmental situation and bearing capability in Poyang Lake basin,agricultural non-point source pollution would be controlled through reducing external source pollution load,restoring river wetland and constructing aquatic ecosystem.After the primary implementation of agricultural non-point source pollution control project,the amount of agricultural non-point source pollution demonstration plot was reduced,and the effluent quality met the first grade(Class A) of national Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB18918-2002).Meanwhile,biodiversity index in river wetland increased by about 30%,so the pollution load entering Poyang Lake was decreased.[Conclusion] The study could provide technology integration and demonstration for the environmental renovation in lakeside belt of Poyang Lake.
