摘要

基于二元水循环理论,在分析城市水资源配置系统结构基础上,构建了考虑水资源质、量均衡的城市用水优化配置模型,并运用多目标求解方法获得水资源分配的可行方案;对信息熵进行改进,构建了系统熵,并将其应用于可行方案的评价中。对昆明市水资源的优化配置计算结果表明,当重视生态效益或者综合考虑生产、生活、环境及生态效益时,系统熵值较小,这将有利于水资源系统的长期健康运行;该方法不仅能对城市用水系统进行简洁有效的分析评价,亦能对用水系统的结构调整、系统发展提供参考意见。
        Dualistic water cycle theory is used to analyze the structure of urban water utilization, based on which the model for urban water allocation is constructed considering the balanced quality and quantity, and the method of multi-objective programming is used to obtain the alternative allocations. System entropy, which is derived from revised information entropy, is used to evaluate the alternatives. This approach is applied in urban water allocation of Kunming, and the conclusion is that, the system entropy will be lower when giving higher weight to the ecological benefit, or giving equal weights to the production, living, environmental and ecological benefits, which will benefit the healthy and sustainable development of water resources system. The case study also shows that this method can not only provide a concise and effective evaluation for urban water system but also give suggestions for the structural adjustment and system development.
