基于熵权的模糊综合评判法在地表水水质评价中的应用

摘要

以郑州市集中式地表饮用水源地花园口水源厂和邙山提灌站为评价对象,根据饮用水源地各监测点的实测数据以及地表水环境质量标准,通过模糊综合评判法对其水质作出了综合评价,在计算评价指标权重时运用了信息论中的熵权法,使评价结果更加客观、合理,从而为有针对性地保护饮用水源,进一步改善水质,优化水资源管理提供科学依据.%Huayuankou water work and Mangshan Lift Irrigation Station are centralized surface drinking water sources of Zhengzhou city. This article will evaluate the water quality of the two water sources according to the measured data and surface water quality standards. Fuzzy comprehensive evaluation method will be selected to evaluate the water quality and entropy method will be used to calculate the weight of the evaluation indexs. The two methods could make the results more objective and reasonable. This can provide a scientific basis for protecting drinking water sources, improving water quality and optimizing water resources management.
