Coupling coordination degree of carbon emissions in production, living and ecology space and influencing factors in the Aksu River Basin

Abstract

Abstract Inland river basins in arid zones have fragile and sensitive ecological backgrounds but are very important ecological niches. Scientific assessments of the coupling coordination development of carbon emissions in production, living, and ecological spaces (PLES) caused by the expansion of man-made oases in these areas, and exploration of the spatial differentiation patterns and influencing factors of carbon emissions in the PLES, are crucial for optimizing basin territorial space and promoting high-quality green development. The study assessed the coupling coordination degree (CCD) of carbon emissions and its spatial differentiation in the basin's in production, living, and ecological spaces. The identified the factors affecting CCD using spatial autocorrelation analysis, Geographically and Temporally Weighted Regression (GTWR) model, and other spatial statistical tools. The results showed that: In the spatial dimension, CCD had the spatial distribution pattern of "high in the east and low in the west". In the time dimension, the evolution of CCD was characterized by "decreasing first and then rising". Factors such as elevation, slope, temperature, precipitation, and population significantly impacted CCD, and had obvious spatial aggregation. In the time dimension, the influence of population on the CCD was relatively stable, while the influence of other factors on the CCD had different trends.
