Study On Environmental Capacity And Comprehensive Environmental Bearing Capacity In Dalian City

Enviormnental earrying capacity is one of a basic theory of environmental seience. It reflects the law of transeference and translation of contamination and also reflects the receiving capacity under a certain kind of enviromnent. Along with the rapid economic development, the conflict between water environmental pollution and water environmental capacity in Dalian City is very serious. By the study of environmental capacity, we can know the actuality of environmental capacity and Comprehensive Load-bearing Capacity of Environment, optimize the environmental capacity and establish basic for the whole improvement of environment in villages and towns of DaLian City. Basing on function classification, the thesis confirms the evaluation units of environmental capacity, and the control object of quality. The thesis investigates the important industrial pollution, living pollution which flow to the evaluation units of environmental capacity. After confirming enter coeffcient, the article calculate the pollution quantity entering of evaluation units. By using various hydrology and quantity data, the article gained the correspond parameter, calculate the ideal environmental capacity of evaluation units , contrast the actuality of polluting headstream and gained Comprehensive Load-bearing Capacity of Resource and Environment. the thesis brings forward the measures protecting and improving Comprehensive Load-bearing Capacity of Resource and Environment by the effectual control of polluting headstream and pollution emission and so on.
