Abstract:
"Production-Living-Ecological" spatial linkage carbon reduction is an important starting point to realize the "carbon peaking and carbon neutrality" strategy. Exploring the influence mechanism of "Production-Living-Ecological" spatial evolution on carbon sequestration and emission is an important foundation to promote regional carbon neutrality and sustainable development. This study undertook the Shiyang River Basin as the research area. It aimed to identify the production, living, and ecological space on the basis of analyzing the evolutionary characteristics of land use pattern and analyze the "Production-Living-Ecological" spatial evolution characteristics and spatial and temporal evolutionary characteristics of carbon sequestration and emission by using related model methods. Furthermore, it discussed the influence mechanism of "Production-Living-Ecological" spatial evolution on carbon sequestration and emission by means of a geographically weighted regression model. The results showed that the area of the unused land in the Shiyang River Basin changed the most from 2000 to 2020, with a decrease of 531.5 km2. During the study period, the dynamic attitude of construction land changed the most, which was closely related to the rapid urbanization and construction of various developmental zones and ecological resettlement areas. From 2000 to 2020, the transformation of ecological structure of production and life in the Shiyang River Basin was mainly characterized by the mutual transformation of production and ecological space, followed by the mutual transformation of production and living space. During the study period, the carbon sequestration in the Shiyang River Basin was at a low level but showed a slow and gradual increasing trend, whereas the overall spatial distribution pattern was gradually decreasing from Qilian Mountain in the southwest to the northeast. The carbon emissions of the Shiyang River Basin showed a significant increasing trend, whereas the overall spatial distribution pattern was "low in the north and south and high in the middle." A significant correlation was observed between the spatial evolution of production, life, and ecology and that of carbon sequestration and emission in the Shiyang River Basin from 2000 to 2020. These results provide scientific basis for optimizing the spatial structure of land and formulating the regional "double carbon" development plan.
