[Objective] The aims of this study are to evaluate the quality and degradation of habitats in the land border zone of Guangxi, and explore their evolutionary characteristics and aggregation effects, so as to provide reference for the construction of regional ecological civilization, the protection of the ecological environment and biodiversity, and the realization of green development. [Methods] Based on the InVest model and Moran's I index, the habitat quality and degree of habitat degradation in the border areas of Guangxi was explored, and their spatiotemporal evolution and aggregation degree were analyzed. [Results](1)From 2000 to 2020, the areas with a low degree of habitat quality degradation in the border areas of Guangxi mainly distributed in areas with good natural environmental conditions such as forests and grasslands, while significant habitat degradation occurred in human activity areas such as cultivated land, construction land, and river water.(2)Overall, the habitat quality score in the border areas of Guangxi was relatively high, with average habitat quality values of 0.739 2, 0.739 5 and 0.734 2 in 2000, 2010 and 2020, respectively. There were some counties and cities that occupied farmland in urban construction, resulting in a decrease in habitat quality.(3)The habitat quality in the border areas of Guangxi had significant clustering in spatial distribution. Although the area of high-high type clustering areas was significantly larger than that of low-low type clustering areas, there were low-low type clustering areas that cut the high-high type clustering areas, resulting in a decrease in the degree of concentration and fragmentation of higher habitats. [Conclusion] Land use changes in the border areas of Guangxi have a profound impact on the quality of regional habitats. In the future, we should strengthen bottom-line constraints and guide human activities.
