In order to study land use changes in arid and semi-arid regions and their ecosystem services value(ESV)spatiotemporal evolution characteristics and driving mechanisms, based on the land use change data in the study area from 2009 to 2017, the dynamics of land use, ESV evaluation model, SPSS and spatial autocorrelation model were used to quantitatively analyzed the ESV spatiotemporal evolution characteristics and driving factors in the study area. The results show that:(1)grassland and cultivated land were the main land use types in the study area; during the study period, the dynamics of urban villages, industrial and mining land, and transportation land had changed greatly, while the dynamic changes of other land use types were small;(2)the total value of ESV had been declining year by year, which decreased from 90.258 billion yuan in 2009 to 89.06 billion yuan in 2017; the spatial distribution pattern of ESV was high in the middle and low in the north and south; the value of each individual service presented the downward trend; the decrease in water area was the main reason for the decrease in adjustment services and support services;(3)the main driving factors of temporal and spatial differences of ESV were population density, urbanization rate, per capita GDP and domestic and foreign tourism income;(4)the spatial correlation results indicated that ESV change rate was negatively correlated with urbanization rate, GDP per capita, and population density; high-high and low-high agglomerations mainly concentrated in the southern region, while high-low agglomeration mainly concentrated in the northern region. The reduction of ecological land area is the main reason for the decline in ESV. Therefore, increasing and maintaining ecological land and controlling the expansion of urban land are the keys to increasing ESV in the study area.
