| Sumario: | In order to make the sponge city construction model more consistent with the inherent characteristics of the city, this paper constructs classification of the sponge city construction index system. We carry out multivariate statistical and cluster analysis based on geographic information system (GIS) and classify the different regions of mainland China, putting forward key points of construction for different types of regions. The results show that climatic factor, hydrological factor and soil factor are the main factors affecting sponge city construction, followed by city scale and level of urban economic development; the third is underlying surface type and geomorphological type. The cities are classified into ten clusters, and they present a continuously zonal or flaky distribution from northeast to southwest on the whole; more than 80% of cities obviously present a continuously zonal or flaky distribution. Each of the nine clusters has at least one pilot city, which can be used as a reference for construction. HIGHLIGHTS
This paper puts forward the method of cluster analysis to classify Chinese cities.;
By using principal component analysis, it is found that the climatic, soil and hydrological factors are the most related to the results of city classification.;
Based on the construction experience of existing pilot cities, the construction emphasis of sponge cities in various types of cities is proposed.; |
