摘要

Research on the coupling of spatiotemporal relationships between land use and cover change (LUCC) carbon emissions and ecosystem service value (ESV) impacts holds significant importance for promoting low-carbon sustainable development. In our study, we examined the spatio-temporal relationship between land-use carbon emissions and ESV at the county level in Shenyang City, China. Research result shows that: (1) The dominant land type in Shenyang is cultivated land. Cultivated land has been decreasing but construction land has been increasing. In terms of spatial pattern, cultivated land is concentrated in areas outside the central urban area, but construction land is mainly distributed in the central urban area and shows a tendency to spread to the suburbs; (2) The spatial and temporal distribution of carbon emissions. From the 2000 and 2020, carbon emissions were in a continuous growth phase, with a growth rate as high as 244.36%.; From a spatial point of view, high carbon emission areas and construction land-intensive areas show a positive correlation, and the areas with high carbon emission intensity are mainly distributed in the central urban areas of Huanggu District, Dadong District, Shenhe District, Heping District; (3) Over the past 20 years, the total ecosystem service value in Shenyang City has increased by $76 million from the perspective of ecosystem services. Furthermore, different land types provide varying levels of ecosystem service value, with cropland and water bodies contributing the highest ESV. In terms of individual ecosystem services, hydrological regulation has consistently provided the highest ESV over the years, while nutrient cycling maintenance has contributed the least; (4) From 2000 to 2020, there is an obvious negative correlation between the intensity of carbon emissions from land use and the intensity of ESV. Our study results have implications for Shenyang, which emphasizes both industry and agriculture in terms of carbon emission reduction.The study fills the research gap regarding land use carbon emissions and ecosystem service value at the county scale in Shenyang City.
