摘　　要：提出以城市基础、工业用水、生活用水、农业及景观用水为社会再生能力评价指标;利用人工神经网络的方法,建立城市水资源社会再生能力评价模型。以黄河流域主要城市为例,进行水资源再生能力评价,并利用Web GIS建立了黄河流域主要城市水资源社会再生能力评价信息发布系统,将评价结果由互联网进行发布。通过对各城市水资源社会再生能力地评价及其结果分析,可了解各城市水务工作中的不足,为水资源开发利用政策的制定起辅助决策的作用。The concept of social renewable capacity of urban water resources is proposed, and the index system of evaluation, including the infrastructure factors, industrial factors, living factors, agricultural and landscaping factors, is established. An evaluation model of water resources social renewable capacity is developed based on artificial neural network. Then the model is applied to analyze the main cities in the Yellow River Basin. At last the Web-GIS based information promulgation system is developed, and the results of evaluation are promulgated via internet. What’s more, the results show that the shortage in the urban water management is obvious. So it will be helpful for the policy makers to make decisions on the utilization of water resources in the future.
