Abstract: Water pollution is one of the prominent problems that affect public health and sustainable economic development.And water pollution prevention pressure of the river basin is becoming increasingly serious with the rapid development of urbanization,industrialization and agriculturalization.Taking Huaihe River Basin as the research object and based on the following internal mechanism of large-scale basin water pollution,this paper carries out the comprehensive evaluation of basin water pollution prevention capability for 35 cities in four aspects,namely,control and treatment,monitoring and warning,supervision and management, prevention and input capability of the river basin.It also explores the driving factors of water pollution prevention with the help of entropy method,GIS spatial analysis and regression model method.The results are shown as follows.(1)Spatial difference of water pollution prevention capability is prominent in the Huaihe River Basin while the pollution prevention ability is higher in the eastern plain area,lower in most parts of the western mountainous area and each of its sub-basins and generally medium to low in main streams and middle reaches to the south of the trunk river.(2)Multiple regression analysis of pollution prevention driving force indicates that the basin endogenous powers,including public education,regional economic development level,play a vital role in water pollution prevention.Exogenous motivation including supervision by public opinion and foreign investment is the key power of regional water pollution prevention.

Key words: water pollution, prevention capability, driving forces, large-scale basin, Huaihe River Basin
