    摘要:

    滇中城市群生态系统健康可持续发展对于中国西部生态安全建设具有重要意义,为响应城市固碳增汇目标及其城市群高质量发展目标,尝试从区域固碳供需的角度,提出契合区域发展特性的优化策略,为促进生态文明的可持续发展提供科学支撑。采用InVEST模型、ArcGIS空间分析工具,对2020年的碳固持服务的供给和需求的供需比值、空间变化特征进行分析,并基于供需比值差异划分不同的碳固持服务发展主体功能区。结果表明:滇中城市群碳固持服务供给大于需求,碳固持优势明显,碳固持需求量整体偏低且呈现中部高四周低的状态,区县发展差异较大。滇中城市群可持续发展规划需加强西北部碳固持服务主体保育工作,协调东南部生态资源与城市发展之间的供需平衡,优化中部固碳服务重点建设区并建立战略合作机制,优化城市基础功能建设,提出“一核两心双翼”的一体化发展格局,以带动周边城市绿色高质量发展。

    Abstract:

    Establishing ecological security in western China greatly depends on the environment of the city cluster in central Yunnan, which is developing healthily and sustainably. To support the sustainable development of the ecological civilization, an optimization strategy that fits the features of regional development from the perspective of regional carbon sequestration supply and demand is proposed. This is in response to the city’s carbon sequestration and sink enhancement goals, as well as the high-quality development of the city cluster. To analyze the supply-demand ratio and the spatial characteristics of the supply and demand of carbon sequestration services in 2020, this paper uses the InVEST model and ArcGIS spatial analysis tools. It then uses these data to categorize various main functional zones for developing carbon sequestration services according to differences in the supply-demand ratio. The findings indicate clear benefits to carbon sequestration in the Central Yunnan Urban Agglomeration, where there is a surplus of available services. The demand for carbon sequestration is generally low, with a high concentration in the city and a low concentration in the surrounding areas, and there are significant regional and county-level development disparities. The Central Yunnan Urban Agglomeration’s sustainable development plan needs to prioritize the preservation of carbon sequestration services in the northwest of the nation, balance the supply and demand for ecological resources and urban development in the southeast, establish a strategic cooperation mechanism in the nation’s center to maximize carbon sequestration services in key construction zones, maximize the construction of urban infrastructure, and propose the “one core, two centers, and two wings” integrated development pattern to promote the environmentally conscious and high-quality development of the surrounding cities.
