Spatial arrangement of the quantity and diversity of basic urban public facilities—a case study of Wuhan by using POI data

全体主题 > Spatial data collection, Analysis, and Visualization

The spatial arrangement of urban basic public facilities is one of the mostly discussed topics in urban planning practice. In existing litera-ture, much emphasis has been on quantity supply and service radius while the diversity of the facilities has not been well considered. Re-garding the principle of equalization in basic public facility arrange-ment, this paper claims that the diversity and spatial equality of basic public facilities call for serious consideration so that people’s various demands can be well serviced. Taking Wuhan as an example, this pa-per uses GIS techniques and the diversity index to measure its spatial characteristics in terms of quantity and diversity. From quantity per-spective, a typical core-periphery pattern is identified. Further, it is found that spatial mismatch exists between quantity supply and peo-ple’s demand. And the overall level of diversity is fairly lower. Addi-tionally, a core-periphery pattern can be identified within the third ring road of Wuhan, while outside the ring there is a huge supply gap in different sites.
