Yili River Basin Water Environment Evolution And Pollutant Transport Processes

The YiLi River valley is Taihu s converge basin .The contaminant of this valley is the main contribution source of Taihu s contaminated load.The contaminant produced in the valley mostly goes into Taihu through NanXin river,therefore the paper through colleting socio-economic data,hydrololgical data,geographical data and water quality monitor about the valley,adopting computer technology,building relevant data base,thus goes on analysing to water-enviroment developmental humane background of th YiLi River valley,studies the water-enviroment developmental progress of the YiLi River valley,and the relationship with the activity of mankind,reveals the relationship between the water-enviroment developmental of Taihu valley and contaminant s producing of the YiLi River valley,ascp.rtams the interactional mechanism and effect between mankind and nature about valley interior,through building numerical model about NanXi river s contaminant transportation,on one side,reveals contaminant s physical law about convection ,diffusion,dilution,mixure ,movement,transformation,degradation , coacervation,adsorption,dissolution and resuspension in NanXin river ,on the other side ,provides scientific foundation and policy-making basis for the valley s ecological construction and economic continued development.
