Research On Load Analysis And Precautious Measures For Agricultural Non-points Source Pollution Of The Water Supply Reservoirs In Zhejiang Province

Due to agricultural non-point source pollution,there is a trend that lots of the water supply reservoirs in Zhejiang Province are suffering from eutrophication.The agricultural non-point source pollution is becoming the leading cause of the water pollution.This article took Zhougongzhai reservoir as an example,analyzing the water quality and conducting survey on pollution source,finding out the main pointer pollution source.Also,further conclusions are reached by comparing the survey results from other four reservoirs.In addition,rainfall runoff,the most important form of transportation of agriculture non-point source pollution,was discussed.Finally,appropriate precautious measures were pointed out,from the process of generation,transportation and transformation.
