| Land use carbon sequestration plays a vital role in facilitating low-carbon sustainable development. Increasing the capacity of carbon sinks in the central area of the Huai River is essential for achieving carbon neutrality in Anhui Province. To analyze the land use carbon emissions in this region and support the high-quality development of the Jianghuai region area, a system for estimating carbon sources and sinks in agricultural, urban, and ecological areas was established. The research employed methods such as standard deviation ellipse, spatial analysis, and multi-scale geographically weighted regression to examine the trends and factors influencing land use carbon emissions in the middle reaches of the Huai River between 2010 and 2020.The findings revealed a notable upward trajectory in the carbon source and net carbon emissions associated with land use within the central segment of the Huai River, alongside a decline in carbon sink capacity. Areas with significant net carbon emissions are predominantly situated in the vicinity of Huainan City, with a gradual expansion towards the northern and southern regions along the Huai River Basin. Factors such as economy, energy, society, and the environment play pivotal roles in influencing carbon emissions from land use, with the economy being the sole sustainable factor among them. Moving forward, it is imperative for the region to bolster the management of the agricultural spatial system, enhance the compensation mechanism for land use carbon sequestration, promote the diversified utilization of urban spaces, facilitate the transition of high-energy-consuming industries, expedite efforts in conserving and rehabilitating ecological spaces, and optimize the structure of land use. |
