摘　　要：覆盖模型通常用于评估空间网络站点规划及网络健壮性,而可视化的覆盖模型可以快速清晰地传递信息,有助于用户理解和分析相关空间数据。该研究基于城市级停车场服务能力空间网络模型,提出了一种可视的动态覆盖方法,其通过ParkingRank算法对各停车场的服务能力进行动态量化,采用具有边界约束的改进加权Voronoi图,将各停车场的量化值映射到地理空间,实现了对整个城市区域无缝且不重叠的覆盖。该模型最大的优点是每个停车场的覆盖范围可随其量化值的变化而动态调整,实现了停车场网络模型的动态可视化,可为未来城市级停车管理与服务提供强大的决策支持。Visualized coverage model is usually applied for the evaluation of site planning and networks robustness in the spatial networks, which can help the users to understand and analyse the spatial data. In this work, a spatial network model of city-wide carparks service capabilities is studied in a visual dynamic coverage way. Firstly, the ParkingRank algorithm was used to model dynamic service capability of each parking lots in real time. Then, an improved weighted Voronoi diagram featuring boundary constraint was introduced to map the ranking value of each carpark to the geospatial space, forming a seamless and nonoverlap coverage over the city. Advantage of the proposed model is that, the coverage scope of each carpark can be adjusted dynamically according to its changing ranking value. By visualizing the parking lots network, it can provide great helps for the city-wide parking management.
