Under the dual constraints of "dual carbon" goal and ecological environment protection, it is of great significance to study the interaction between carbon emissions caused by land use change and the value of ecosystem services to promote the realization of carbon neutrality goals and regional high-quality development. Selecting the main urban area of the Changzhutan urban agglomeration as the research object, based on the data of land use, energy consumption and socio-economy in the five periods from 2000 to 2020, the grid analysis method and bivariate spatial autocorrelation model were comprehensively used to explore the temporal and spatial evolution characteristics and interaction between land use carbon emissions and ecosystem service value. The results showed that:(1) From 2000 to 2020, different degrees of transfer occurred among various land use types, among which cultivated land and forest land decreased by 392.77 km² and 268.10 km², respectively, and construction land increased by 661.80 km². (2) From 2000 to 2020, the net carbon emissions of Changzhutan urban agglomeration was positive, and the overall performance was carbon emissions, and the net carbon emissions increased significantly from 1 099.84×10⁴ t to 4 109.21×10⁴ t. The carbon emission intensity showed the spatial distribution characteristic of high center and low edge. (3) ESV decreased slowly from 392.06×10⁸ yuan to 292.86×10⁸ yuan, with a decrease of 5.34%. The ESV intensity showed the spatial distribution characteristic of high in the Xiangjiang River basin and low in the surrounding area. (4) There was a significant negative correlation between land use carbon emission intensity and ESV intensity, and the local agglomeration types of them could be divided into four types, which were high and high, low low, low high, high and low, respectively, and their spatial distribution ranges were different. The results provide a reference for revealing the spatiotemporal relationship between carbon emissions caused by land use change and the value of ecosystem services.
