摘要 |
In response to the inherent requirements of low-carbon land spatial planning in Jiangxi Province and the lack of existing research, this paper explored the mechanism of spatial form elements of Poyang Lake urban agglomeration on urban carbon emissions. Based on generalized linear regression and geographically weighted regression models, this paper analyzed the spatiotemporal distribution characteristics of carbon emissions, the spatiotemporal relationship between urban form index and carbon emissions, and the spatial differentiation of the intensity of dominant factors from 63 county-level administrative units in the Poyang Lake city group from 2005 to 2020. The results showed that: ① The carbon emissions of urban agglomerations around Poyang Lake are generally increasing, and the spatial distribution of carbon emissions is characterized by high-value concentration in the middle and low-value agglomeration in pieces; ② The main driving factor for the spatial heterogeneity of carbon emissions was the expansion of built-up area; ③ Improving urban compactness and optimizing urban form could effectively reduce urban carbon emissions. The results showcased the correlation between urban spatial landscape pattern and the spatiotemporal distribution of carbon emissions, which could make the low-carbon land spatial planning in the Poyang Lake city group more reasonable and practical. |
