Abstract: Establishing a monitoring and evaluation method of mine ecological restoration based on UAV remote sensing images to reveal the spatial distribution characteristics and influencing factors of mine vegetation restoration and providing basis for ecosystem management.An abandoned quarry in Weibei dry belt was taken as the study area,Remote sensing images of the study area after restoration were obtained by unmanned aerial vehicles,combined with the high-resolution images before treatment,the vegetation cover of the study area was divided by green leaf index (GLI)and fractal dimension of GLI was calculated to evaluate the ecological environment changes before and after restoration.Combined with geographic detectors,the influencing factors affecting ecological restoration effect were identified,and corresponding ecological restoration measures and monitoring suggestions were put forward.After treatment,GLI value and vegetation coverage increased significantly,and vegetation types showed diversity.Slope is the key factor restricting vegetation restoration in the study area,and physical and chemical characteristics of reconstructed soil also have great influence on regional ecological restoration.The research results provide basic data for mine ecosystem regulation and enrich the evaluation techniques and methods of ecological restoration effect.
