基于ArcGIS的南昌市旧城中心区城市公园绿地可达性评价及布局优化研究

Research on Accessibility Evaluation and Layout Optimization of Urban Park Green Space in the Central District of Nanchang Old City Based on ArcGIS

城市公园是城市居民日常休闲游憩的主要场所,其合理布局不仅事关城市公共资源的公平分配,而且对提升全体城市居民获得感、幸福感和安全感意义重大。文章以南昌市旧城中心区城市公园绿地为研究对象,利用ArcGIS软件中的网络分析法,基于步行、自行车行和公交车行这三种城市居民基本出行方式,对研究区域内的城市公园绿地可达性进行评价分析,并提出增加城市公园绿地数量、完善城市道路交通网络和加强城市绿道规划建设三条城市公园绿地布局优化策略。

The urban park is the principal place for daily leisure and recreation of urban residents.Its reasonable layout is not only related to the fair distribution of urban public resources,but also of considerable significance to enhancing the sense of happiness,happiness,and security of all urban residents.The article takes the urban park green space in the central area of the old city of Nanchang as the research object,using the network analysis method in Arc GIS software,based on the three basic ways of urban residents walking,bicycle trips and bus trips.Accessibility was evaluated and analyzed,and three strategies for optimizing the layout of urban park green space were proposed,including increasing the number of urban park green spaces,improving urban road traffic networks,and strengthening urban greenway planning and construction.
