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.
