摘要：基于兴趣点数据,通过ArcGIS空间分析方法探讨城市的经济、社会、交通、休憩活力,结果显示:①贵阳城市活力非均衡空间分布,老城区占城市活力的约50%,其他县区活力主要以斑块形式分布。②贵阳活力呈现“东北-西南”发展方向,社会活力分布范围最广,体现了社会主义优越的均等化及公平性。③贵阳活力空间分布集聚程度为:经济活力>休憩活力>社会活力>交通活力,贵阳经济活力空间布局注重效率,贵阳作为休闲旅游城市休憩活力布局广泛,同时作为山城,贵阳交通还需更一步提升。④在距离为16km时,城市活力因子集聚程度达到峰值,16km之后随着距离的增大,活力因子空间集聚程度呈现出逐渐减弱趋势。
Based on the point of interest data,through the ArcGIS spatial analysis method of kernel density estimation,standard deviation ellipse,average nearest neighbor distance,Ripley’s K function to explore the city’s economic,social,transportation,leisure vitality.The results show that:①the urban vitality of Guiyang is not balanced in spatial distribution,the old urban area accounts for about 50%of the urban vitality,and the vitality of other counties is mainly distributed in the form of patches.②Guiyang’s vitality presents the development direction of“northeast southwest”,and its social vitality is the most widely distributed,which reflects the superior equalization and fairness of socialism.③The spatial distribution and agglomeration degree of Guiyang’s vitality is as follows:Economic vitality>leisure vitality>Social vitality>Traffic vitality.The spatial distribution of Guiyang’s economic vitality focuses on efficiency.As a leisure and tourism city,Guiyang has a wide distribution of leisure vitality.At the same time,as a mountain city,Guiyang’s transportation needs to be further improved.④When the distance is 16km,the agglomeration degree of urban vitality factor reaches the peak.After 16km,with the increase of the distance,the agglomeration degree of urban vitality factor gradually decreases.
