基于两步浮动承载区模型的五华区城市公园可达性分析

Accessibility Analysis of Urban Parks in Wuhua District,Kunming City Based on the Two-Step Floating Bearing Area Model

基于两步浮动承载区模型和ArcGis软件的空间分析工具,以昆明市五华区的10个城市公园为例,从城市公园分布(供给)和街道人口数量(需求)2个角度进行了可达性分析。结果显示:①黑林铺街道可达性指数最高,为6.4952;护国、华山街道可达性指数居中,为3.2474;普吉、莲花、丰宁街道和昆明国家高新技术产业开发区可达性指数最低,为0。②研究区街道范围内城市公园分布极为不均,且街道与街道之间可达性指数差异巨大。③五华区整体呈现出的可达性指数较为低下,街道人口数量并未对城市公园可达性产生积极正面的影响。旨在为昆明市五华区城市公园的分布选址提供参考。

Based on the two-step floating bearing area model and the spatial analysis tool of ArcGIS software,taking ten urban parks in Wuhua District of Kunming as an example,the accessibility is analyzed from the perspectives of urban park distribution(supply)and street population(demand).The results show that:①the accessibility index of Heilinpu street is the highest,which is 6.4952.The accessibility index of Huguo and Huashan streets is in the middle,which is 3.2474.The accessibility index of Phuket,Lianhua,Fengning streets and Kunming National High-Tech Industrial Development Zone is the lowest,which is0.②The distribution of urban parks in the study area is extremely uneven,and the accessibility index between streets is very different.③The accessibility index of Wuhua District as a whole is relatively low,and the number of street population has not had a positive impact on the accessibility of urban parks.The purpose of this study is to provide reference for the construction site selection of urban parks in Wuhua District,Kunming City.
