Vegetation restoration in abandoned mines is crucial for ecosystem recovery and sustainable development. However, the assessment of effectiveness long-term sustainability through appropriate methods remains a significant challenge. This study aims to evaluate vegetation Mianshan mine Dongzhi County, China, three years after completion project, using analytic hierarchy process (AHP) fuzzy comprehensive evaluation (FCE) methods. Drone oblique photography field survey transects were applied determine growth geological conditions across different habitats, including base, terrace, slope behind terrace. An indicator system was developed assess effectiveness. Results indicated that overall moderately effective, with coverage rate (restored-to-native ratio) 62.0% 66.7%, respectively. The terrace habitat exhibited highest, while base showed fair highest on but species diversity lowest. had lower greater diversity, more planted invasive species. low poor conservative than slope. Key factors influencing habitats included topography (e.g., gradient), soil texture (clay or gravelly soil), moisture, selection, planting strategies. evaluated AHP FCE methods, highlighting influence topography, conditions, selection outcomes diverse habitats.

Open-pit coal mining drives socioeconomic development but imposes significant environmental impacts. The timely monitoring of dynamics is essential for sustainable resource exploitation and ecological restoration. However, existing studies often rely on predefined boundaries, limiting their applicability in unknown regions. This study proposes an innovative approach that leverages the intra-annual frequency index (ACFI) to identify potential open-pit areas, integrates Rays method monitor temporal changes. By applying a discriminative rule, this effectively distinguishes mines from other disturbances enables spatiotemporal without need prior knowledge locations. Applied Chenbarhu Banner coalfield, Inner Mongolia, achieved 92% accuracy kappa coefficient 0.84 identifying areas. It distinguished active closed mines, detecting key features with 94% (kappa = 0.86). also identified directions extents, such as 4–13° Baorixile mine 69–141° Dongming mine, while excluding non-mining areas high precision. A strong correlation (r 0.929, p < 0.01) between annual area production further validated approach. provides accurate, scalable tools supports decision-making regulatory management processes.

Under the interference of climate warming and human engineering activities, degradation permafrost causes frequent occurrence geological disasters such as uneven foundation settlement landslides, which brings great challenges to construction operational safety road projects. In this paper, spatial temporal evolution surface deformations along Beihei Highway was investigated by combining SBAS-InSAR technique frost number model after considering vegetation factor with multi-source remote sensing observation data. After comprehensively factors change, degradation, anthropogenic disturbance, landslide processes were analyzed in conjunction site surveys ground The results show that average deformation rate is approximately −16 mm/a over 22 km section study area. on pavement related topography, subsidence more pronounced areas high topographic relief a sunny aspect. Permafrost roads area showed an insignificant trend, at landslides large deformation, significant trend. Meteorological monitoring data indicate annual minimum mean temperature increasing rapidly 1.266 °C/10a during last 40 years. associated precipitation freeze–thaw cycles. There are interactions between important influences settlement. Focusing process zone can help deeply understand mechanism change impact hazards zone.

Fractional vegetation cover (FVC) plays a significant role in assessing ecological quality and protection, as well soil water conservation. As typical rare-earth resource county China, Dingnan County has experienced rapid development due to mining, resulting alterations cover. To elucidate the spatio-temporal changes within over past 35 years effects of natural human factors on these changes, spatial temporal variations FVC were analyzed using Landsat-TM/OLI multispectral images taken 1988, 1995, 1997, 2002, 2006, 2013, 2017, 2023. The findings indicate that (1) coverage decreased from 1988 followed by gradual increase; (2) high is predominantly found forested areas maintain their state, while central town mining exhibit generally low coverage; (3) there are regional differences relationship between environmental County. This research facilitates alignment ion-type with thereby promoting sustainable area providing scientific guidance for local governments formulate more effective management protection strategies ecosystem. Additionally, this offers foundation globally develop policies informed decision-making regarding development.
