The study on spatial evolution and mechanism of urban transportation facilities in Lanzhou Belt City based on POI
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 stud-ies the influencing mechanism.The results show that:the urban transportation facilities show the charac-teristics of"east dense west"and the degree of agglomeration is enhanced,the urban transportation facili-ties 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 trans-portation 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 distribu-tion 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 trans-portation network jointly affect the spatial evolution of urban transportation facilities.
