基于百度POI数据的福州市公园分布特征研究

Research on Distribution Characteristics of Fuzhou Park Based on Baidu POI Data

基于百度POI数据,结合Arcgis软件的数理统计和空间分析功能,通过基尼系数、最邻近点系数和核密度三个指标对福州市公园的分布进行研究.结果表明:福州市各个区县之间的公园数量差距非常悬殊,公园的分布为高度聚集状态,呈现一个高核密度区和6个次核密度区.建议城市公园建设一是要制定统筹兼顾的发展规划方案,最大程度满足每个公民享受公园的权利;二是建立多维的公园建设管理模式,将公众和专家学者纳入公园建设的机制中去.

Based on Baidu POI data,combined with the mathematical statistics and spatial analysis functions of Arcgis software,the distribution of Fuzhou Park is studied by three indicators:Gini coefficient,nearest neighbor coefficient and nuclear density.The results show that the number of parks in various districts and counties in Fuzhou is very different.The distribution of parks is highly concentrated.Fuzhou Park presents a high nuclear density zone and six subnuclear density zones.It is recommended to build urban parks.First,we must formulate a comprehensive development plan to meet the rights of every citizen to enjoy the park.Second,establish a multi-dimensional park construction management model,and incorporate the public and experts and scholars into the mechanism of building a park.
