Classification of sponge city construction modes based on regional features

Abstract

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 GIS and classify the different regions of mainland China, put 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.

Assessing the impact of mega-city construction engineering on urban livability: an explorative study of Yan'an

“…The relevant problems existing in the urban development of OD provide a lesson for the construction of ND and have become a key element for improvement in MECC engineering. The construction of large-scale projects has the potential to significantly alter the surrounding environment due to factors such as land use changes, resource consumption, and pollution emissions ( 44 , 50 , 61 ). It is essential to carefully assess and mitigate these impacts to ensure sustainable development and the preservation of ecological balance.…”
