Spatiotemporal Variation and Influence Factors of Vegetation Cover in the Yellow River Basin (1982–2021) Based on GIMMS NDVI and MOD13A1

Depicting the spatiotemporal dynamics of vegetation cover in Yellow River Basin (YRB) and delineating influences climate change human activities on have been significant importance for understanding surface earth systems general also formulating ecological protection plans YRB particular. This study uses GIMMS NDVI dataset from 1982 to 2015 MOD13A1 2000 2021 explore spatial temporal characteristics period with an attempt reveal influencing factors. The distribution variation are analyzed by maximum value composite, Theil-Sen median trend analysis, Mann–Kendall test. Combined mean annual temperature precipitation same period, factors discussed using binary linear regression analysis residual analysis. Results show that: (1) multi-year average values increase northwest southeast that covers fluctuate relatively greatly along increasing a growth rate 0.019/(10a). Understandably, monthly single-peak pattern, August being peak time (0.4936). (2) 77.35% studied areas characterized exhibiting during (i.e., 1982–2021). (3) Vegetation is affected combined effects activities, more observed amelioration cover.
