Through the analysis of existing rural non-point source pollution control technologies, the authors studied the feasibility of the non- point source pollution control in Guizhou, and put forward kaey factors affecting the non-point source pollution control. It was found that: the rural non-point source pollution in Karst area of Guizhou was facing a serious challenge, it was closely related with agricultural production development, ecological development and construction, environmental health etc., as well as the water security of the Yangtze River and the Pearl River downstream residents. It was concluded that: Guizhou was restricted by geographical environment, natural conditions for farming and living environment was very limited; a steady pace of industrialization nowadays, the uneven distribution of resources in urban and rural environmental protection, and the increase of population had become the key factors affecting non-point source pollution in rural Guizhou.
