Abstract: | This paper presents an analysis of the distribution characteristics and change trend of agricultural non -point source pollution over the past decade in Dongguan .Based on the calculation of the emission load and the quantity into river of the agricultural non-point source pollution in 2000 and 2010 .Results show that: the agricultural non-point source pollution load in Dongguan has declined overall from 2000 to 2010.Particularly, the amplitude reduction of the quantity into river of TP is 73.5%, which is the largest .As for the contribution rate of agricultural non-point source pollution , the contribution rates of rural domestic wastewater and solid waste show an increasing trend;while chemical fertilizer application and distributed livestock wastewater show a reducing trend , and the distributed livestock wastewater ’ s reducing trend is the most remarkable . |
