Study On Water Environmental Capacity And Environmental Quality Assessment In Huhhot's Rivers

Study on water environmental capacity and water environmental quality assessment are the important data base for river pollution control and reached water environmental function target.The author monitors the water quality of Huhhot's rivers to analyses the current water from 2002-2007.Based on the results,the annual variation tendencies of pollution index in the Yellow River,DaHei river,XiaoHei river,Hun river,ShiLaWuSu river and Xi river was obtained.The individual pollution index,the composite pollution index and contributing degree of pollution index were used to research the main pollution factors of each river and the water quality evaluation result of plentiful water period and dry period.Water environmental capacity of rivers,reduction amount and reduction rate was obtained by Investigation on hydrology and pollution source and Water Quality Model Calculation.The paper further makes clear the Pollution Status of Huhhot's rivers.The results obtained provide the basis for river pollution control.The paper provided data support for reach the target of water environmental function blocks.
