Spatial–Temporal Pattern of Urban Land Green Use Efficiency and Its Influencing Factors in Guizhou Province, China, Based on County Units by Zhongchun Xu, Hongqin Chen, Wei Song

“…In terms of the numbers, there was a gradual downward trend in the number of high-efficiency cities. (2) Based on the spatial evolution characteristics, there was a positive correlation in the ULGUE among county cities in Guizhou Province, and the high- and low-value areas were comparatively more widely located in the central–east and west sides of Guizhou Province, respectively. (3) Among the factors influencing the level of the ULGUE, the level of economic development, industrial structure upgrading, and environmental regulation mainly played a positive facilitating role, while the material standard of living of the population, the GDP content, the green development level, government financial support, and the population size played a negative inhibiting role. …”
