ABSTRACT
Studying the temporal and spatial evolution characteristics of the ecological level of urban production
space (ELUPS) in the upper reaches of the Yangtze River (URYR) is significant for promoting the
green development of the Yangtze River basin. This paper takes municipal districts of 31 prefecturelevel
cities in the URYR in China as the research unit, and adopts the coupling coordination model,
the standard deviation coefficient, spatial autocorrelation analysis, correlation coefficient, and regression
analysis to carry out the research. The results show that: (1) ELUPS has gone up and become more
concentrated in the URYR from 2010 to 2019. However, the mutual influence among cities is weak,
and no agglomeration effect has been formed as a whole. (2) In 2019, ELUPS showed a spatial pattern
of “partial prominence, low in the west, around Guiyang and along the Chengdu-Chongqing line”.
(3)Permanent resident population and per capita GDP are the influence factors of ELUPS. It is a crucial
way to improve the ELUPS in the URYR to strengthen the connection between cities and promote
the high-quality development of each city.
