中文摘要:
      土地利用固碳增汇是低碳绿色发展的关键。淮河中游地区碳汇能力提升是安徽省碳达峰碳中和的关键环节。为揭示该区域土地利用碳排放特征,促进江淮地区高质量发展,构建农业、城镇和生态空间的碳源/汇估算体系,运用标准差椭圆、空间分析及多尺度地理加权回归等方法,探究2010—2020年淮河中游地区土地利用碳排放演变特征及影响因素。结果表明:淮河中游地区土地利用碳源和净碳排放均呈增长态势,碳汇能力降低;净碳排放的高值区域集中在以淮南为核心的区县,沿淮河流域向南北方向逐渐扩散;经济、能源、社会和环境是土地利用碳排放的主要影响因素,但仅经济为持续因素。未来该区域应加深农业空间系统治理,完善土地利用碳汇补偿机制;加强城镇空间混合利用,推动高能耗产业退出;加快生态空间保护与修复,优化土地利用结构。
英文摘要:
      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.
