The Agricultural Area Pollution Of Drinking Water Sources Investigation And The Countermeasure Research

For this study, we choose the second drinking water resourse of Changsha city, Zhushuqiao reservoir as a typical study district. We get some rather abundant basic data by the investigation on agricultural area pollution in the reservoir district and it's drainage area's fertilizer,rural living and feed of livestock and fowl.
