Abstract: The quality of the ecological environment often determines whether human society can achieve sustainable development or not. It is of practical importance to explore how and to what extent rural development affects the ecological environment to achieve regional rural revitalization and sustainable development. Taking Shaanxi Province as the research object and counties as the research unit, the remote sensing ecological index (RSEI) for a long time series was used to characterize the spatial and temporal changes and changing trends in ecological environment quality in the province. The factors influencing the quality and spatial differences in the ecological environment were explored with the help of spatial and temporal geographical weighted regression models. The study show that:(1) the overall changing trend of ecological environment quality from 2000 to 2020 was positive, with the RSEI value increasing from 0.483 3 in 2000 to 0.651 2 in 2020. The ecological environment quality grades were good and relatively good, with the percentage of areas increasing from 40.14% to 63.43%, which are concentrated in the mountainous areas of southern Shaanxi Province and Yan'an City. (2) The overall trend was a "rapid improvement → slow change for the better" from 2000 to 2020. The areas with an improved ecological environment are much larger than those with a degraded ecological environment. (3) The influence of the population, land, and industry factors on the ecological environment showed an obvious spatial variability. The main factors that affecting the influence mode were the proportion of forest land area, the proportion of rural settlement area, fertilizer use per unit area, and total mechanical power per unit area. It is suggested that a sub-regional, scientific, and rational rural revitalization policy should be formulated for the future development process to coordinate rural development and the ecological environment in Shaanxi Province.
