Abstract:

The study of the spatial-temporal evolution of the “production-living-ecological” space and the effect of carbon emission under carbon peak and carbon neutrality goals target is of practical significance for the sustainable development of ecological economies in arid areas and the realization of green and low-carbon development in land space. This study examined remote sensing monitoring data and energy consumption data for the Xinjiang in five periods: 2000, 2005, 2010, 2015, and 2020. Using the “production-living-ecological” spatial dynamic index, transfer matrix, and carbon emission coefficient, the spatial-temporal evolution characteristics and carbon effects of “production-living-ecological” in Xinjiang in the past 20 years were analyzed using the ArcGIS spatial analysis functions. The results show that: (1) the comprehensive dynamic index of the study area reached 0.11% in the past 20 years, with the highest from 2005 to 2010. (2) in the past 20 years, the area of the “production-living-ecological” space has changed greatly, revealing the rapid expansion of “living-production” space and declining trend in “ecological space”. and (3) “living-production” space is the main contributor to carbon emissions in the study area, and underwent continuous growth. In terms of carbon absorption, the contribution of the “ecological-production” space to carbon absorption is relatively high. The study provides scientific support for the construction of a spatial classification system for the “production-living-ecological” space that meets the emissions reduction needs of Xinjiang; thus, it is of great significance for the construction of high-quality “Belt and Road” and the realization of low-carbon development, carbon peak and carbon neutrality goals in arid regions.
