公共交通出行方式下,综合性公园的可达性及配置的均衡性是评价城市公园绿地配置和本地居民享有公共服务设施权利的重要指标。以南京市为例,建立公共交通复合网络,以时间成本距离分析综合性公园服务的区域水平和基于站点位置的可达性;以基尼系数判断全局和15分钟生活圈下综合性公园分布的均衡性及贡献度;建立新公园选址采样点,分析增加新公园选址后的基尼系数变化的空间分布。结果表明:以可达性为前提,以基尼系数为衡量指标,可以量化分析公园分布均衡性,通过基尼系数更新变化的空间分布,可以明确新规划公园对综合性公园分布均衡性的影响,能够确定优化选址区域。为城市新综合性公园规划提供量化的区域范围参考,优化城市公园布局并提高城市公园可达性和分布均衡性。 |

Abstract: |
Under the mode of public transportation, the accessibility and allocation equity of comprehensive parks are important indicators for evaluating urban park green space allocation and residents’ rights to enjoy public service facilities. Taking Nanjing as an example, this research builds a composite network of public transportation and, based on time-cost distance, analyzes the regional service level of comprehensive parks and their accessibility relative to the position of transportation stations. Additionally, the research adopts the Gini coefficient to judge the distribution equity and contribution of comprehensive parks respectively from the global perspective and the perspective of 15-minute living circle. The research also establishes new park site sampling points to analyze the spatial distribution of Gini coefficient changes upon addition of new park sites. The results show that the equity of park distribution can be quantitatively analyzed with accessibility as the premise and Gini coefficient as a measurement indicator; the impact of newly planned parks on the distribution equity of comprehensive parks can be clarified and the optimal site selection area can be determined through the spatial distribution of Gini coefficient updates and changes. The research can provide a quantitative area coverage reference for urban new comprehensive park planning, to improve the layout, accessibility and distribution equity of urban parks. |
