基于ArcGIS的南京、西安景点空间分布比较研究

Comparative Study on Spatial Distribution of Scenic Spots in Nanjing and Xi'an based on ArcGIS

近年来,随着城市扩张和城镇化水平不断提高、人口变化等因素,城市景点的布局与人口分布的关联程度也日益加强。文章基于POI景点数据为例,应用核密度估计法和Getis-Ord Gi*指数法分析景点的分布密度、热/冷点分布及其与人口的空间关联程度。对南京和西安两个历史文化名城的分析结果表明:经济发展水平更高、基础设施更完善的城市更具旅游吸引力,景点与人口分布紧密相关,这有助于进一步总结城市景点与人口分布的关系与经验,并对其他景点城市品质提升提供重要参考。

In recent years,with the urban expansion,the continuous improvement of urbanization level,population change and other factors,the correlation between the layout of urban scenic spots and population distribution has also been strengthened day by day.Based on POI scenic spot data,this paper analyzes the distribution density,hot/cold spot distribution and its spatial correlation with population by using kernel density estimation method and Getis-Ord GI*index method.The analysis results of two famous historical and cultural cities,Nanjing and Xi'an,show that cities with higher economic development level and better infrastructure are more attractive for tourism,and scenic spots are closely related to population distribution,which is helpful to further summarize the relationship and experience between urban scenic spots and population distribution,and provide an important reference for the improvement of urban quality of other scenic spots.
