摘要/Abstract

摘要：

自组织游径网络的活力提升是城市更新规划的重要目标。由于老城区游径网络存在不连续性和断头路现象，居民游憩活动的舒适性受到了挑战，而游径网络的自组织性意味着自上而下的规划设计模式难以匹配市民需求。如何自下而上地推演游憩规划的空间活力，进而识别潜力地块，是提升城市游径网络品质的重要命题。文中以广州市老城区为案例，基于复杂网络理论，构建游径网络的非连续性和空间活力测度指标；以GPS轨迹数据识别既有游径网络的非连续区段，定量探讨了基于市民游憩行为的非连续路段空间的识别和城市更新改造项目的活化作用，推演更新项目实施带来的潜在影响。游径网络的非连续性分析表明，当前广州市老城区游径路段的非连续度总体较低，连接程度较好，但由于区位和历史遗留问题，仍有部分路段存在明显的非连续现象。城市游径网络的空间活力推演结果表明，城市更新项目对自组织游径网络会产生一定的正面影响，可依据推演分析来判定城市游憩品质提升项目的实施计划和日程。本研究从规划和交通维度出发，对城市的自组织特性进行了有益探索，弥补了“自上而下”式规划对城市自组织游径网络考虑不足的缺陷。

Abstract:

Improving the vitality of self-organized recreational path network is an important goal of urban renewal planning. Due to the discontinuity and the existence of dead end roads in the recreational path network in old towns, the comfort of residents’ recreational activities is restricted. The self-organization of recreational path network means that the top-down planning and design mode is difficult to match the needs of citizens. How to deduce the spatial vitality of recreation planning in a bottom-up mode and then identify potential land plots is an important issue to improve the quality of urban recreational path network. By taking the old town in Guangzhou as an example, this paper constructs the indicators of break degree and spatial vibrancy based on the complex network theory. Then, by using GPS trajectory data to identify the breaks in the existing recreational path network, the identification of discontinuous breaks based on citizen recreation behavior and the activation effect of urban renewal projects are quantitatively discussed, and the potential impacts brought by the implementation of renewal projects are simulated. The discontinuity analysis shows that the break degree of the recreational path network in the old town in Guangzhou is generally low, and the connection degree is good, but there are still some obvious breaks due to the street location and historical problems. Moreover, the results of spatial vibrancy deduction show that urban renewal projects have a positive impact on the self-organized recreational path network, and that the implementation plan and schedule of urban recreation quality improvement projects can be determined according to the deduction analysis results. This study makes a beneficial exploration of urban self-organizing characteristics from the perspectives of planning and transportation, and makes up for the deficiency of top-down planning in considering urban self-organized recreational path network.

Key words: recreational path network, urban planning, urban renewal, discontinuity, spatial vibrancy, planning simulation
