| 英文摘要 | Vegetation dynamics in the Qilian Mountains (QLMs) are influenced by complex topography, climate variability, and human activities, yet the underlying mechanisms remain insufficiently understood. This study assessed spatiotemporal vegetation trends using Theil-Sen trend analysis and the Hurst index across distinct subregions (eastern, central, western; mountain and valley areas). Partial Least Squares Structural Equation Modeling (PLS-SEM) was employed to analyze how climatic, anthropogenic, soil, and topographic factors shape spatial variation in the Normalized Difference Vegetation Index (NDVI). Residual analysis was used to quantify the relative contributions of climate change and human activities. The results showed that: (1) Since 2001, vegetation in the QLMs exhibited an overall improving trend (87.15 %), with localized degradation (2.66 %) mainly located in the eastern and central sections. (2) The spatial variation of NDVI in the QLMs is primarily driven by climatic factors, followed by human activities and topographic factors, with soil properties having the least impact. The pathways of these factors are similar across different regions, but their intensity varies significantly. As vegetation in most areas gradually adapts to climate change, the influence of climatic factors has weakened. (3) Climate change and human activities contributed 68.50 % and 31.50 % to interannual changes of vegetation, respectively. This study provided valuable insights for ecological protection and sustainable land management in the QLMs. |
