“…While developing coal resources, The increasing impact of disturbance and even destruction on the ecological environment has attracted varying degrees of attention both domestically and internationally. Some scholars [4][5][6][7] focusing on the current ecological restoration situation in the Qilian Mountains, have proposed countermeasures and suggestions to strengthen unified planning, delineate ecological red lines, and actively improve the ecological compensation mechanism. However, there is limited literature available on the ecological restoration of coal mining in the Muli area.…”

“…Climate change has promoted VC increase in the QLM on a large scale. However, due to the impacts of human activities such as overgrazing, mining, and hydropower development, vegetation degradation and land desertification in local areas of the QLM were prominent in recent decades [38,39], thus affecting the overall role of the ecological security barrier [40]. To control the degraded lands and restore regional ecological functions, the local government has implemented a series of ecological protection and restoration projects in the QLM, such as a grazing-forbidding project, a grassland-livestock balance project, and a grassland ecological award and compensation project [41,42].…”

The Qilian Mountains (QLM) are an essential ecological security barrier in northwest China. Identifying the driven pattern of vegetation change is crucial for ecological protection and restoration in the QLM. Based on high-resolution vegetation coverage (VC) data in the QLM from 1990 to 2018, linear trend analysis was employed to examine the spatiotemporal dynamics of VC in the QLM, while correlation analysis was utilized to establish relationships between VC change and environmental factors. Multiple correlation analysis and residual analysis were adopted to recognize the climatically and anthropogenically driven pattern of VC change. The results showed that VC in the QLM presented a remarkable upward trend in volatility from 1990 to 2018. The significant increase areas accounted for 59.32% of the total, mainly distributed in the central and western QLM, and the significant decrease areas accounted for 9.18%, mostly located in the middle and eastern QLM. VC change showed a significant positive correlation with precipitation change and annual average temperature, while it exhibited a significant negative correlation with annual average precipitation, current VC status, livestock density, and slope. Climate change played a leading role in the increase of VC, and the impact of precipitation was significantly higher than that of temperature. Affected by climate change, the VC of alpine steppes and temperate steppes increased the most. Under the human interference, VC decreased significantly in 9.2% of the region, of which shrubs fell the most, followed by alpine meadows and forests. This study can provide certain guidance for local ecological protection and restoration efforts.

Spatial heterogeneity of ecosystem services trade‐offs among ecosystem service bundles in an alpine mountainous region: A case‐ study in the Qilian Mountains, Northwest China

In mountainous areas with diverse climate, topography, and socio-economic status, ecosystem services (ES) trade-offs may differ largely in space. However, few researches have spatially identified the trade-offs and influencing factors of ES in different regions. We selected the Qilian Mountains (QLM) as a study area and eight key ES [grain production (GP), livestock production (LP), water yield (WY), carbon sequestration (CS), water erosion prevention (WAEC), wind erosion prevention (WIEC), habitat quality (HQ), and sightseeing (SS)] were evaluated through spatially explicit models. K-means clustering was used to identify the ES bundles. Trade-offs between ES were identified using factor analysis. Natural and human drivers that influence the spatial differentiation of ES were explored through redundancy analysis. The results showed the eight ES had obvious spatial heterogeneity and could be clustered into three bundles. In the entire QLM, there were obvious synergies between most ES, especially GP, LP, CS, and SS. However, several trade-offs existed in different bundles (e.g., HQ with GP, LP, CS, and SS in bundle 1; HQ with GP, LP, and SS in bundle 2; WIEC with WY and WAEC in bundle 3). Natural factors were the main factors affecting the spatial differentiation of ES, among which vegetation coverage, elevation, precipitation, and slope have higher explanatory degrees, but differences among three bundles were great. The influence of human factors on the provisioning and cultural services was relatively high in local areas. This study can provide references for formulating regional development strategies in the QLM and other mountainous regions.
