[Multi-scale Spatial and Temporal Evolution of Carbon Emissions and Influencing Factors in Gansu Province]

It is one of the goals of current social development to achieve regional high-quality development and meet people's needs for an ecological environment. Taking Gansu Province as an example, the spatial and temporal changes in carbon emissions in Gansu Province from 1992 to 2021 and their influencing factors are analyzed based on a multi-scale perspective using spatial autocorrelation, cold hotspots, and geographic probes. The results showed that： ① The total carbon emissions in Gansu Province fluctuated and increased from 1992 to 2021, but the growth rate was decreasing. ② In terms of the type of growth, low growth was mainly concentrated in the relatively economically developed districts and counties, and high growth was mainly concentrated in the economically underdeveloped districts and counties, regardless of the city and state scales or county scales. ③ Carbon emissions in Gansu Province showed a significant global spatial positive correlation at the county scale, with the aggregation capacity weakening and then increasing, the high-high aggregation area moving from Longzhong to Longdong, and the low-low aggregation area distributed in the south of Gansu. ④ The influence of factors on carbon emissions tended to grow with the enlargement of the study scale, and the influence of regional GDP on the spatial differentiation of carbon emissions has been maintained at a high level. Whether at the city-state scale or the county scale, the explanatory power of a single factor on carbon emissions was weaker than the interaction of the factors.
