This study focused on the Jinjie mining area by addressing severe resource and environmental issues arising from excessive coal in Shenmu County, Northwest China. Multi-source remote sensing data GF-1 Landsat 8 OLI were utilized this study. Specifically, fused ecological index (FRSEI) was constructed to conduct a detailed evaluation analysis of eco-environmental quality 2013 2023. The results indicated that overall exhibited trend initial improvement, followed degradation, then improvement again over decade. mine pits their surrounding areas significantly lower than level, confirming destructive impact eco-environment. Meanwhile, as area, County is actively utilizing subsidence develop photovoltaic power generation industry, aiming achieve green low-carbon transformation. Although construction plants initially led degradation condition vegetation FRSEI, both gradually improved after operational. Furthermore, comparing FRSEI with (RSEI) calculated solely using data, we found high degree similarity between two, thereby validating stability accuracy FRSEI. not only provides high-precision support for monitoring but also highlights potential multi-source fusion technology improving accuracy, further providing scientific basis formulating sustainable development strategies specifically eco-environment areas.

ABSTRACT Ecosystem services supply–demand (ESSD) is a key considering factor in regional ecological security. Based on the background, this study proposed dynamic local and tele‐coupling coordination degree (DLTCCD) model further analyzed its influencing factors by combining it with machine learning model. The main conclusions show that: (1) There existed great imbalance ESSD of Yangtze River Economic Belt (YREB) where upstream area was supply downstream demand area; (2) DLTCCD YREB as whole has been increasing can more objectively reflect changes coupling (CCD); (3) In future, government should prioritize dual focus demographic trends urbanization levels to foster balance YREB. This aims identify effectiveness protection projects so provide theoretical support for cross‐regional compensation policy planning area.

ABSTRACT The West Qinling Mountains is the western extension of Mountains, geographic demarcation line between north and south China. Under control Loess Plateau, northern part has obvious transitional features in terms topography, climate, soil, vegetation. In order to explore effects Plateau on habitat quality (HQ) we selected five typical counties with different percentages area based geomorphic types, water system, vegetation zone, elevation, analyzed spatial temporal differentiation characteristics HQ their influence mechanisms help InVEST model geographical detector (GD) model. results showed that: (1) From 2000 2020, cultivated land continued decrease, while constructed increase. three regions a decreasing trend an increasing forest as within region decreases. Transition Zone increase construction county (2) changes bipolar sharpening phenomenon. moderately low grade high (3) mean first then decreasing. Zone, three‐level gradient low, medium, high. generally distribution south, was mainly distributed north. formation this verified that ecological environment had influenced Mountains. (4) Land use intensity (LUI) population density were dominant factors causing regions, NDVI NPP have always played key role variation synergistic enhancement effect various promotes change regional HQ.

Urban fringe areas, serving as transitional zones between urban and rural landscapes, are characterized by their nature, high dynamics, spatial heterogeneity. Identifying the extent of an urban–rural (URF) analyzing its evolutionary characteristics crucial for planning development. However, limited research exists regarding identification a URF analysis spatiotemporal evolution in polycentric cities. Using Chengdu case study, this employed K-means clustering method to identify patterns from 2010 2020 based on multi-source data. The results indicate that (1) can reasonably efficiently cities; (2) exhibited structure with “main center-subcenter” pattern, where was adjacent main subcenters, assuming overall annular wedge shape; (3) there significant expansion northeast–southwest direction 2020, accompanied substantial land use changes. driven dual mechanisms suburbanization urbanization, exhibiting such singular functions, dispersed chaotic use, fragmented increasing complexity. This study extended URFs, aiding understanding growth providing decision support integrated development areas.
