[Objective]The aims of this study are to explore the response of ecosystem service value to land use change and predicting future trends, and to provide scientific reference for land use pattern planning in the arsenic sandstone area. [Methods]Based on the remote sensing images of the four phases of sandstone area from 2000 to 2020, the change characteristics of LUCC and ESV in the past 20 years were analyzed based on GIS technology and ESV evaluation methods. The response of LUCC induced by ESV was revealed. The development trend of LUCC and ESV was predicted by using Markov model. [Results](1)In 2000—2020, the total area of LUCC remained unchanged, and the increase of construction land was the most obvious, with a total increase of 762.73 km2 and a growth rate of 4.57%. The grassland decreased by 548.79 km2 in total, with a reduction rate of 3.28%.(2)The overall level of ESV showed a downward trend, from 19 949.65 million yuan to 18 997.19 million yuan, a decrease of 4.78%, of which grassland ESV changed the most, decreasing by 746.29 million yuan, accounting for 78.35% of the overall decline rate.(3)ESV was positively correlated with the changes in grassland, woodland, cultivated land, water area and construction land, and negatively correlated with unused land.(4)It is predicted that the area of cultivated land, forest land, grassland and water area will decrease to 96.69%, 98.94%, 94.27% and 99.12% of those in 2020 in the next 10 years. Construction land and unused land will increase to 150.03% and 121.61%, and the overall ESV level in sandstone area will continue to decrease to 92.81%. [Conclusion]The areas of cultivated land, forest land, grassland, and water are decreasing, while the area of construction land and unused land will increase. ESV will continue to decrease, and there is a linear relationship between ESV changes and land use changes. In the future, the area of construction land will increase, and ESV will continue to decrease. Reasonably adjusting the area of construction land is beneficial for ecological construction and vegetation restoration and reconstruction in the sandstone area of the Yellow River Basin.
