In order to explore the difference of land use function evolution and its impact on ecological environment in different gradients of plateau traditional agricultural areas, based on the land use data of 2000, 2010 and 2020, the land use transition matrix and regional eco-environmental quality index were used to analyse the characteristics of land use function evolution and its eco-environmental effects in the study area. The results show that:(1)The land use functional structure changes in the plateau agricultural region are varied along a vertical gradient. In the past 20 years, the land use for living and ecological purposes increased by 2 784.18 hm2 and 2 561.29 hm2, respectively, while the land for production purposes decreased by 5 345.47 hm2. The ecological land use is mainly concentrated in the middle and high undulating geomorphic areas. The land for production and living is mainly concentrated in the low-relief landform area.(2)The spatial difference of eco-environmental effect in plateau agricultural area is obvious, the study area function of land use change on the influence of the ecological environment quality overall is smooth, the ecological environment quality index are generally well maintained at 0.598 2 level, especially in the middle and high undulating landforms in the north and central regions, the agricultural production land such as slope farmland and low efficiency garden land has been transformed into ecological land dominated by forest land, which has promoted the stable and good development of regional ecological environment. However, due to population agglomeration, land carrying capacity and excessive utilisation, agricultural structure adjustment and urbanization, occupation of cultivated land, forest land and grassland in the low-relief landform area of central and southern China are frequent, resulting in a local ecological environmental quality degradation trend. In general, with the shift of population pressure and the weakening of the degree of land use, the overall pattern of land use in the plateau agricultural area tended to be optimised, the sustainability of land use function was enhanced, and the ecological environment quality in the plateau agricultural area developed well.
