Climate change and human activities are reshaping the structure function of terrestrial ecosystems, particularly in vulnerable regions such as agro-pastoral ecotones. However, extent to which climate impacts vegetation growth these areas remains poorly understood, largely due modifying effects human-induced land cover changes on sensitivity climatic variations. This study utilizes satellite-derived indices, datasets, data investigate influence both ecotone northern China (APENC) from 2001 2022. The results reveal that productivity, indicated by kernel Normalized Difference Vegetation Index (kNDVI), varies depending type APENC. Moreover, ridge regression modeling shows pre-season conditions (i.e., precipitation temperature) have a stronger positive impact growing-season productivity than growing season temperature, while effect vapor pressure deficit (VPD) is negative. Notably, kNDVI exhibits significant (p < 0.05) 34.12% region negative VPD 38.80%. model explained 89.10% total variation (R2 = 0.891). These findings not only emphasize critical role historical contemporary shaping but also provide valuable insights into how adjust agricultural animal husbandry management strategies improve regional adaptation based information previous seasons fragile regions.
