黄河流域水环境变化分析及其对策研究

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

黄河流域生态环境的恢复和保持良性循环已成为黄河水利委员会当前乃至将来一个极其重要的工作目标。通过对黄河流域污水排放量及其变化趋势以及造成的危害进行分析,可以对黄河流域的污水排放造成的生态环境恶化在不同时间和空间上有一个较全面的认识,分析的结果为黄河流域生态环境恢复目标的实现提供十分有用的科学依据。

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.
