[Spatiotemporal Relationship Between Carbon Emissions and Ecosystem Service Value in Shanxi Province Based on Land Use Change].

Abstract

Ecosystem services are related to human well-being， and land use change （LUCC） can affect carbon emissions and ecosystem service value （ESV）. Studying the spatiotemporal relationship between the two is of great significance for promoting green and sustainable development. Therefore， in the context of the "dual carbon" goal and the construction of ecological civilization， Shanxi， as a coal-producing province， was taken as the research area， based on land use and socio-economic data from 2000 to 2020， using spatial autocorrelation analysis methods to explore the spatiotemporal evolution characteristics and interaction laws of carbon emissions and ESV. The results indicate that： ① From 2000 to 2020， the main land types in Shanxi Province were cultivated land， grassland， and forest land. The area of construction land and forest land showed an increasing trend， while the area of other land types showed a decreasing trend. ② The net carbon emissions from land use in Shanxi Province have been increasing year by year， from 34.65 million tons in 2000 to 124.80 million tons in 2020. The high value areas of land use carbon emissions intensity were mainly concentrated in the central region and continued to extend to the surrounding areas， while the low value areas were mainly distributed on the edges of various cities， and their area continued to decrease. ③ The ecosystem service value in Shanxi Province was 269.13 billion yuan in 2000 and 264.69 billion yuan in 2020， with a slow decline in value. Forest and grassland had the highest contribution rates to ESV. The spatial distribution of ESV varied significantly， with significant annual changes. ④From 2000 to 2020， there was a significant negative correlation between land use carbon emission intensity and ESV intensity in Shanxi Province. The stronger the land use carbon emission intensity， the weaker the ESV intensity， and it passed the p-value test. The research results contribute to providing scientific basis for land use planning and ecological environment policy formulation in Shanxi Province， thereby promoting industrial transformation and upgrading as well as sustainable socio-economic development.
