摘要: 在3 km×3 km格网下可视化表达了2020年广西百色市土地利用与生态系统服务价值的空间分布格局,并运用Moran’s I指数和LISA集聚图探讨了二者的空间集聚特征和空间自相关关系。结果表明,百色市各土地利用类型表现为显著的正相关和集聚分布,且所表现的空间集聚或异常的区域明显不同;百色市生态系统服务价值整体上呈显著的正向空间自相关和高-高、低-低集聚,空间集聚度较高,在局部零星出现高-低、低-高集聚;林地及其生态系统服务价值均表现出最强的正向空间自相关与空间集聚性,其他用地类型及其生态系统服务价值的正向空间自相关性与空间集聚性表现出相同的变化趋势。百色市应继续实施生态保护与修复政策,严禁城镇建设触碰生态保护红线,从总体上提升土地利用效率与生态系统服务价值,促进区域经济、社会与生态可持续发展。

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
