Change Analysis of Water Environment in Yellow River Catchment And Strategy Research

Returning to normal eco-environment and retaining sound cycle in Yellow River catchment are very important target at present and in future.In this paper,through the analysis about the volume and change tendency of polluted water emission and damage caused by emission,a more complete cognition with regard to aggravation of eco-environment in different time and space in Yellow River Catchment is presented.The analysis result of this paper can provide useful science basis for realization of the target to return normal eco-environment in this catchment.
