Abstract In order to investigate the effects of land use change on ecosystem service value (ESV) in Guangxi
Autonomous Region, the random forest algorithm was used to classify the land use of the 5 periods of Landsat series
remote sensing images from 2000 to 2020, the land use dynamic degree and land use transfer matrix methods were
used to reveal the land use change patterns, the ecosystem services value was calculated by using the equivalence
factor method, with its spatiotemporal variation characteristics explored, and the intrinsic link between each land use
type and changes in ecosystem service values was analyzed. The results showed that forest land and arable land were
the main land use types in Guangxi, and the area of construction land had been increasing year by year, mainly by
encroaching on arable land. The dynamic degree of single land use type was in the order of unutilized land >
grassland > construction land > cropland > water > forest land. The overall ESV in Guangxi showed a fluctuating
downward trend. The value of unidirectional ecosystem services was dominated by hydrological regulation and
climate regulation. In terms of spatial distribution, the ESV was characterized by a low spatial distribution in the
middle and high spatial distribution in the surrounding area. For the changes of ESV in Guangxi in the last 20 years,
grassland, forest land and cropland were the main contributing factors and sensitive factors.
Key words land use change; ecosystem service value; spatiotemporal variation; Guangxi
