摘要：Ecosystem service value (ESV) is an important indicator used to measure the quality of the regional ecological environment, and land use/cover change (LUCC) has a crucial impact on it. Based on three periods of land use data for Guangxi, China, in 2000, 2010, and 2020, in this study, the spatial and temporal change characteristics of the LUCC were analyzed, and the equivalent factor method was used to calculate the total ESV in Guangxi. Finally, the spatial autocorrelation and spatial aggregation characteristics of ESV in Guangxi were analyzed to explore the impact of land use/cover changes on ecosystem service values in Guangxi. The results show that the utilization areas of water and artificial surface continuously increased from 2000 to 2020, with the largest increase in the area of artificial surface, which increased by 3390.67 km2. The areas of the forest land, shrubland, and sea continuously decreased, of which the forest land area decreased by 5679.39 km2. The areas of the cultivated land and grassland initially increased and then decreased, exhibiting a small overall increase. During the study period, the total ESV in Guangxi initially increased and then decreased, with an overall increase of 1.295 billion RMB. This was caused by the increase in the area of water and grassland. The distribution of ESV in Guangxi has a significant positive spatial correlation, and the distribution of ESV in Guangxi shows a high north and low south, and the ESV high-high value aggregation areas were concentrated in the mountainous areas in northeast and northwest Guangxi. The results of this study provide an important theoretical basis for the rational development and utilization of land resources in Guangxi and for the coordination of socio-economic development and environmental protection.
