| 摘 要： | 传统水系连通方案编制主要以水系结构为主导，忽略了连通后对水系功能的影响，本文在进行城市水系布局时，将水系连通形状和连通功能两部分纳为一体来制定水系连通方案。基于中心性评价方法，提出河段重要性计算方法来定量刻画河段重要性；借助隶属度函数建立连通功能及其表征参数的函数关系，据此量化水系连通功能效果；以河网连通功能达标率和水系连通性满足度为优选目标，建立结构-功能耦合下的水系连通方案两阶段优化模型，优选最佳闸门联合调度方案。以清潩河许昌段为实例，优化原河网及不同水系连通情景的连通性。研究表明:经过优化后，原河网清潩河水系连通性总体较好，但护城河附近和饮马河的连通性较差；连通护城河和清泥河、连通饮马河和小洪河能极大地提升护城河附近和饮马河的水系连通性。

| Abstract: | The traditional water system connectivity scheme is mainly dominated by the water system structure, ignoring the influence of connectivity on water system function. In the layout of the urban water system, the connecting structure and function of the water system are integrated to formulate the connecting scheme of the water system. Based on the centrality evaluation method, a method is proposed to quantitatively portray the importance of river segments. The functional relationship between the connectivity function and its characterization parameters is established with the help of the affiliation function, and the effect of the water system connectivity function is quantified accordingly. The two-stage optimization model of the water system connectivity scheme with structure-function coupling is established with the river network connectivity function achievement rate. The objective is to determine the effectiveness of the water system connectivity, and based on this, the optimal joint gate scheduling scheme is selected. Taking the Qingyi River as an example, the study shows that the overall connectivity of the water system of Qingyi River in the original river network is good, but the connectivity near the Hucheng River and Yinma River is poor. Improving the Hucheng River-Qingni River and the Yinma River-Xiaohong River connections could greatly enhance the connectivity of the water system near the Hucheng River and Yinma River. |
