Against the backdrop of the increasingly intensified global climate change and human activities， exploring the spatio-temporal coupling mechanism between vegetation greenness and human activity intensity is of great significance to reveal the differentiated characteristics of the human-land relationship in different regions. Based on MODIS NDVI data from 2000 to 2023， combined with Theil-Sen trend analysis， Mann-Kendall significance test， Human Activity Intensity Index （HAI）， bivariate spatial autocorrelation， and Geodetectors， the evolution characteristics of vegetation greenness in the temporal and spatial dimensions in the Weihe River Basin were systematically analyzed. Additionally， the intrinsic connection between vegetation greenness and climatic factors as well as human activities were thoroughly investigated. The results showed that： ① During the period from 2000 to 2023， the vegetation greenness showed a good level， with an average annual growth rate of 0.453%. ② The intensity of human activities generally showed the spatial distribution pattern of high in the southeast and low in the northwest. The area of low strength decreased by 17.41 percentage point， and the areas of medium-low strength， medium strength， medium-high strength， and high strength increased by 2.83， 5.95， 4.42， and 4.21 percentage point， respectively. ③ The spatial and temporal correlation characteristics of vegetation greenness and human activity intensity reflected the different characteristics o...
