基于GIS的洛阳市洛龙区城市公园绿地可达性分析及布局优化研究

Accessibility Analysis and Layout Optimization of Urban Park Green Space in Luolong District of Luoyang City Based on GIS

通过ArcGIS建立以城市道路网络为基础的道路矢量数据库和包括公园面积、出入口、位置等要素的城市公园矢量数据库。采用基于GIS的网络分析法对洛阳市洛龙区城市公园的可达性进行评价,发现4种服务盲点类型:真空盲点、车行服务盲点、步行服务盲点和隐形盲点。针对不同类型的盲点提出修建综合性公园,增加街旁绿地、城市道路、口袋公园、公园出入口,扩大公园广场面积等优化策略,以解决居民日常游憩和假日游览的需求。

The road vector database based on urban road network and the urban park vector database including park area,entrance and exit,location and other elements were established through ArcGIS.The accessibility of urban parks in Luolong District was evaluated by network analysis method,and four types of service blind spots were found:vacuum blind spot,vehicle service blind spot,pedestrian service blind spot and invisible blind spot.Aiming at different types of blind spots,this paper put forward optimization strategies such as building comprehensive parks,increasing roadside green space,urban roads,pocket parks,park entrances and exits,and expanding the area of park squares,so as to meet the needs of residents for daily recreation and holiday tours.
