路网形态对城市内部公园空间分布的影响——以广州市南沙区为例

Discriminant Analysis of the Service Function of the Urban Park System Associated with the Urban Road Network – the Case of Nansha District, Guangzhou

  • 摘要: 摘要:城市化可持续发展需要关注城市主体人的城市化,在此背景下,对城市内部公园系统的空间布局进行研究具有重要意义。本文对城市内部公园系统进行分类,并基于POI数据综合运用核密度估计法、最邻近距离法、标准差椭圆法及欧氏距离法等GIS空间分析方法,结合空间句法理论,从公园系统空间布局分析、城市路网形态分析、路网形态对城市内部公园系统空间布局影响三个角度对区域公园系统进行评价,得出以下结论:①公园系统总体呈多中心聚集式分布,形成四大聚集核心和若干次核心,分布格局总体呈西北-东南模式,与区域路网形态相适应。城市公园分布相对分散,自然公园分布较为集聚。②全局尺度与局部尺度上城市路网形态特征具有较大相似性,呈现出三大整合度核心,整体上较依赖于高速公路等城市通勤体系带动。③区域内公园系统空间布局依赖于全局及局部尺度上的路网形态。其中,城市公园与路网空间相关性高,说明城市公园系统较受区域路网影响较大,相比而言受全局路网影响稍大与受局部路网影响;自然公园与路网空间相关性较低,自然公园系统几乎不受城市路网空间的影响,相比而言受全局性通勤路网影响更为明显。

     

    Abstract: Abstract: The sustainable development of urbanization needs to focus on the citizen of the city. In this context, it is important to evaluate the spatial distribution of urban park system. Based on the reference of domestic and foreign literature, this paper classified the system of Nansha District City Park in Guangzhou. Based on POI data, we use kernel density estimation method, the nearest distance method, standard deviation ellipse method, Euclidean distance method and other GIS spatial analysis method. Combined with the theory of space syntax, we start from three aspects: the spatial arrangement of urban park system, the morphology of urban road network, the impact of the spatial arrangement of urban park system, which caused by urban road network. This paper draw the following conclusions: ①The urban park system has a multicenter distribution in this area, and the distribution direction is northwest-southeast. The distribution patterns of different types of parks are different, the city park have two distribution cores and relatively dispersed, and the nature park have three distribution cores and they are concentrated. ②The characteristics of urban road network on the overall scale and local scale have great similarity, showing three high value integrations. As a whole, Nansha road network is more dependent on the highway and other urban commuter system. ③Park space layout depends on the road network both on overall scale and local scale. The spatial distribution of the urban park is high affected by the network form, and the spatial distribution of the nature park is little affected by the network form. This study provides a reference for the park system space planning, which is contribute to the reasonable allocation of urban park system.
