Abstract: The spatial distribution pattern of land use and ecosystem service values in Baise City, Guangxi in 2020 was visualized under a 3 km×3 km grid, and their spatial aggregation characteristics and spatial autocorrelation were explored using Moran’s I index and LISA agglomeration map. The results showed that, the various land use types in Baise City showed a significant positive correlation and agglomeration distribution, and the spatial agglomeration or anomalous areas were obviously different. The ecosystem service values of Baise City as a whole showed a significant positive spatial autocorrelation and high-high aggregation, and low-low aggregation,with a high degree of spatial aggregation. High-low aggregation and low-high aggregation appeared sporadically in local areas. Forest land and its ecosystem service values both showed the strongest positive spatial autocorrelation and spatial agglomeration, the positive spatial autocorrelation and spatial agglomeration of other land use types and their ecosystem service values showed the same trend. Baise City should continue to implement ecological protection and restoration policies, strictly prohibit urban construction from touching the "red line" of ecological protection, improve land use efficiency and ecosystem service value in general, and promote regional economic, social and ecologically sustainable development.

Key words: land use/cover change, ecosystem service values, grid, spatial autocorrelation analysis, Baise City, Guangxi
