Abstract: Accurately grasping the relationship between the agricultural source pollution and agricultural economic growth at the present stage of China, and understanding the stage of China's agricultural source pollution, will help the government taking appropriate measures to prevent and control the pollution. Based on the EKC theory, this paper selects the indicators of Agricultural source pollution and economic growth data from 1995 to 2015, and analyzes the agricultural economic growth and the agricultural surface pollution in China. Study found that the four types of pollution sources that cause agricultural pollution are N-type and inverted U-shaped respectively. And the use and discharge of different pollution sources are at different stages of the curve. The use of pesticide tends to be gentle, the use of fertilizer and the use of agricultural film is increasing, emission of poultry droppings is falling. Finally, combined with the current situation of China's agricultural source pollution control, this paper puts forward the policy suggestions from four aspects:pesticide pollution source, fertilizer pollution source, agricultural film pollution source and poultry pollution source.
