Coupled Coordination and the Spatial Connection Network Analysis of New Urbanization and Ecological Resilience in the Urban Agglomeration of Central Guizhou, China

Abstract

This study evaluates the new urbanization (NU) quality and the ecological resilience (ER) of 33 districts and counties in the Urban Agglomeration of Central Guizhou from 2010 to 2020. For this purpose, we used a modified coupled coordination degree (CCD) model, spatial autocorrelation analysis, and trend surface analysis to analyze the spatiotemporal evolutionary characteristics of the CCD of NU and ER. Meanwhile, we used a modified gravity model and social network analysis to investigate the spatial connection network (SCN) characteristics of the CCD of NU and ER. The results show that (1) the general NU quality has increased significantly in the Urban Agglomeration of Central Guizhou. There is, however, a downward trend in ER. (2) For the CCD of NU and ER in the Urban Agglomeration of Central Guizhou, there is coupling dissonance, with a double U-shaped arc, characterized by west > north > south > east > central. (3) The network density increases and then decreases. Network connectivity is 1, and network efficiency decreases and then increases. (4) During the study period, the SCN is characterized by significant core–edge characteristics; there are no “island nodes” in the SCN.
