The environmental quality of a mining city has direct impact on regional sustainable development and become key indicator for assessing the effectiveness national policies. However, against backdrop accelerated urbanization, increased demand resource development, promotion concept ecological civilization, cities are faced with major challenge balancing economic protection. This study aims to deeply investigate spatial temporal variations its driving mechanisms mineral resource-based cities. utilizes wide coverage multitemporal capabilities MODIS optical thermal infrared remote sensing data. It innovatively develops index (RSEI) algorithm PIE-Engine cloud platform quickly obtain RSEI, which reflects environment. evolution characteristics in seven typical China from 2001 2022 were analyzed. Combined vector mine surface data, variability impacts activities environment quantitatively separated explored. In particular, taken into account by creating buffer zones zoning statistics analyze response relationship between RSEI these factors, including distance area percentage area. addition, drivers 2019 analyzed through Pearson correlation coefficients pixel 10 natural, economic, mining. Regression modeling was performed using random forest (RF) model, ranked order importance factor assessment. results showed that (1) changed significantly during period, negative significant. (2) areas low values closely related (3) generally lower than average level gradually as site increased. (4) increase size initially exacerbates environment, but is weakened beyond certain threshold. (5) most important affecting followed DEM, GDP, precipitation. great advancing formulating strategies.

AbstractsLarge-scale ecological restoration is not realistic, we can guide regional through the construction and optimization of networks (EN), which in turn promotes enhancement ecosystem health. However, methods perspectives existing studies on EN are relatively homogeneous, to some extent restricts our ability improve health ecosystems. In research, attempted establish an pathway (referred as CSC model) with objectives promoting connectivity (C), stability (S) continuity (C) between regions into ecosystems ENs, identification priority zones, topology, analysis balance supply demand services (ESs), empirically demonstrated it Jiuquan City, China. The results show that: (1) Barrier points pinch main contributors reduced EN, focusing them repair areas (especially for where two overlap) local EN. (2)Both Add edges Node degrees (AND) Betweenness (ANB) strategies enhance ENs. ANB strategy exhibits highest overall serves best solution improving (3)Areas ESs low high overlap ENs pressure potentially degradation anthropogenic impacts, prone damage sources or breaks corridors, thus affecting sustainable development should be taken a area future protection.(4)The optimized edge attack experiment's elemental connectivity, persistence ecosystems, conducive enhancing region.

Manganese ore, as an important strategic metal resource for the country, was subject to unreasonable mining practices and outdated smelting technologies in early China, leading severe ecological damage areas. This study examines trends vegetation cover change historical manganese areas of Yongzhou under influence policy, providing technical references mitigating impact these legacy offering a basis adjusting mine restoration policies. paper takes area City, Hunan Province case selects multiple periods Landsat satellite images from 2000 2023. By calculating Normalized Difference Vegetation Index (NDVI) Fractional Coverage (FVC), spatiotemporal changes driving factors coverage 2023 were analyzed. The analysis results show that, terms time, 2012, decreased 0.58 0.21, while 2013 2023, it gradually recovered 0.21 0.40. From spatial perspective, where artificial reclamation conducted, mainly mildly moderately degraded, no carried out, significant degradation observed. Mining activities primary anthropogenic force behind decrease coverage, effective protection projects proactive policy guidance main forces increase area.

Objectives: The game between socio-economic development and ecological has always been the core issue in coal areas, but internal mechanism of tradeoff cooperative dynamic change ecosystem services mining areas under long-term mineral resources is still lacking in-depth research. Methods: Therefore, taking Shendong area as an example, this study used InVEST model to evaluate changes four major service functions from 1990 2020, namely, water yield (WY), net primary productivity (NPP), soil conservation (SC) habitat quality (HQ). Meanwhile, correlation analysis was explore trade-off synergistic relationship among these services. On basis, coupling effect further discussed by using constraint line method. Finally, key drivers trade-offs/synergies region are explored geodetectors explanations each influence factor for RMS errors obtained. Results: results show that 1) retention decrease first then increase, increase slowly, mainly southeast area. 2) In terms relationship, all showed hump-like is, there obvious threshold effect. 3) area, dominant services, occurs quality. 4) driving tradeoff/synergy, land use type, temperature, rainfall main factors cause spatial differentiation synergy intensity Conclusions: provide a scientific basis improvement environment sustainable utilization exploitation.

The stability of ecosystems in high mountain canyon areas is poor, and the interaction between humans land complex, making these more vulnerable to destruction. Quantitatively assessing ecosystem service value (ESV) revealing its spatiotemporal evolution patterns driving factors play a crucial role construction regional ecological barriers assurance security. This study focuses on Upper Minjiang River as research area, using InVEST model Equivalent Factor Method estimate ESV. combination aims address inadequacy reflecting variability ESV across different regions, sensitivity data changes that results insufficient accuracy assessments. By harnessing spatial au-tocorrelation geodetector method, we unravel characteristics show that: (1) From 2000 2020, ESVs estimated by two estimations increased 31.28% 22.47%, respectively, both indicating eco-environment quality upper has been continuously improved. (2) When Moran's I was greater than 0.5 (p < 0.05), clustering "High-High" "Low-Low" obvious. It clear varies geographically. High values are primarily found area's center southern well banks River, whereas low common region's northern region. (3) Slope human activity intensity (HAI) principal contributors differentiation ESV, 60% types were classified dual-factor enhancement. synergistic reinforcing effects HAI, slope, elevation, temperature collectively shape shifts distribution. offers novel evaluative lens supplying sturdy support for crafting specific preservation rejuvenation strategies coming years.

The study of vegetation on disturbed lands is necessary to solve environmental problems and restore the natural potential such areas as soon possible. paper presents a taxation characterization 15-30-year-old mixed stands artificial origin growing in reclaimed clay quarry. Species composition, projective cover aboveground phytomass absolutely dry form living ground were determined. Field data collected using common methods: sample plots survey plots. 39 species recorded, which classified into 13 families 5 cenotypes. proportion distribution by cenotypes, well ratio are presented. degree floristic composition commonality studied communities herbaceous plants, determined Jaccard coefficient, small (from 0.24 0.57). It was established that conditions research area at quarries, it possible highly productive plantations with predominance coniferous species.
