Preliminary Study On The Measurement Of Environmental Capacity Of Surface Water In Changchun City

The measurement of environmental capacity of surface water isof great significance to the environmental protection andmanagement.New national pollution prevention and managementregulations will be based on the environmental capacity in the future.Measurement results of environmental capacity of surface water inChangchun City will have a crucial impact on the next step of economicdevelopment in Changchun City, therefore environmental capacity tobe measured and check against must be consistent with the actualsituation in Changchun. If measured too large, it would cause thedeterioration of environmental quality in the course of the economicdevelopment. Otherwise, it would limit economic development andincrease treatment costs. The paper from the perspective of environmental management andcapacity utilization, based on the scientific assessment of thestatus quo of the water quality in Changchun City and water qualityobjectives of the water environment functional area, established therelationship about pollution source-water environmentalquality,and analysed utilization,protection and distribution of thewater environmental capacity from the water environmental functionarea to water the basin. The paper identified the environmentalcapacity of the water environment, provided scientific basis andtechnical support for the environmental management and a certainframe of reference for water protective speciality programming inChangchun City.
