Abstract: The spatial and temporal changes of land use in the Taihang Mountains were analyzed based on the land use data from 1985 to 2020. Based on the economic statistical data, the value of ecosystem services in the Taihang Mountains was evaluated, and its spatial and temporal characteristics were analyzed by the equivalent factor method. The relationship between ecosystem service value and land use type change was explored by the grey correlation method. The results showed that the dominant land use type in Taihang Mountains area shifted from 1985 to 2020, the dominant land use type in 1985 was grassland, and the dominant land use types in 2020 were arable land, grassland and forest land, respectively. From 1985 to 2020, the value of ecosystem services in the Taihang Mountains showed a decreasing trend, with a total decrease of 19.057 billion yuan, including a reduction of 54.367 billion yuan in the value of grassland ecosystem services. In terms of spatial distribution, the value of ecosystem services in the Taihang Mountains showed a spatial distribution characteristic of “high in the middle and low around”, with high value of ecosystem services in the central high-altitude areas of Taihang Mountains and relatively low value of ecosystem services in the surrounding low-altitude areas. The grey correlation degree between each land use type and the total value of ecosystem services in Taihang Mountain area from small to large was forest land, cultivated land, grassland, unused land, wetland and water body, and the grey correlation degree of the three former was 0.84,0.83 and 0.82 respectively, which was much larger than that of the other three land use types, indicating that the value of ecosystem services was most affected by forest land, cultivated land and grassland. Relevant government departments should effectively protect basic farmland and improve the quality of arable land in the study area, strengthen the conservation of forests in the study area, build an excellent ecological environment, and establish a good compensation mechanism for regional ecological and environmental management.
