城市群水资源协同配置模型及超长期配置方案研究

Water resources collaborative allocation model and ultra long-term scheme in megalopolis

针对城市群实施跨越式发展过程中出现的新情况和新问题,以长吉联合都市区为例,开展城市群水资源配置模型及超长期配置方案研究,通过构建面向城市群的水资源多维多目标配置模型和长系列逐月调节计算及对比分析,提出2050年超大时间跨度的水资源配置推荐方案和配置工程布局,为进一步优化城市群水资源配置总体格局和保障跨越式发展供水安全提供重要依据。

In terms of the new situation and problems caused by the rapid development of megalopolis,ex-ploring the water resources collaborative allocation model and ultra-long-term water allocation scheme arethe solutions for the sustainable use of water resources for megalopolis. We choose Chang-Ji megalopolis asthe case study. A multi-dimensional and multi-objective model was established to optimize water resourcesallocation for the megalopolis. This paper compared the results of long-term monthly water resources regula-tions under different schemes and proposed an ultra-long-term water resources allocation layout and waterconstruction distribution of Chang-Ji megalopolis in 2050. The model with multi-dimensional and multi-ob-jective functions provides a feasible approach to optimizing the overall layout of water resources allocationand offers fundamental support to guarantee a reliable water supply during the rapid urbanization.
