摘要: 基于兰州中心城区2011—2022年市内交通设施的POI数据,运用空间分析法从空间形态、方向分布和冷热点分析其空间演化、研究影响机制.结果表明:市内交通设施呈“东密西疏”的特征且集聚程度增强,市内交通设施和停车设施由“单核”变为“单核心、多散点并存”的空间形态,公交设施由 “一主一次”变为“一主多次”并在边缘出现多个散点;市内交通设施呈“西北—东南”方向分布,重心经历 “东南-西北-东北”的偏移轨迹,具有向西北和东北扩散的趋势,公交设施的分布比停车设施更分散;市内交通设施和停车设施在城关区的热点由沿路散点转为沿路线性分布,最终呈现以东方红广场为核心,其他三区由沿路散点转为线性分布,公交设施热点相对分散,沿道路呈线性分布;“人文—地理”环境的约束、政府规划的调控、交通网络完善的推动共同影响市内交通设施的空间演化.

Abstract: Based on the POI data of urban traffic facilities in Lanzhou Central City from 2011 to 2022, this paper analyzes the spatial evolution:spatial form, directional distribution and hot and cold spots, and studies the influencing mechanism. The results show that: the urban transportation facilities show the characteristics of “east dense west” and the degree of agglomeration is enhanced, the urban transportation facilities and parking facilities change from “single core” to “single core, multiple scattered points coexist”, and the public transportation facilities change from “one main once” to “one main many times” and multiple scattered points appear at the edge. Urban transportation facilities are distributed in the direction of “northwest-southeast”, and the center of gravity experiences an offset track of “southeast-northwest-northeast”, with a trend of spreading to the northwest and northeast, and the distribution of public transportation facilities is more dispersed than parking facilities. The hot spots of urban traffic facilities and parking facilities in the Chengguan District change from scattered points along the road to linear distribution along the road, and finally show Dongfanghong Square as the core, and the other three districts change from scattered points along the road to linear distribution; The hot spots of public transportation facilities are relatively dispersed and linearly distributed along the road. The constraints of the “humanity-geography” environment, the regulation of government planning, and the promotion of the perfect transportation network jointly affect the spatial evolution of urban transportation facilities.

Key words: POI, Lanzhou Belt City, urban transportation facilities, spatial evolution, evolutionary mechanism
