Impact of Human Activities and Climate Change on Grassland   Productivity in Xilingol League YAN Huimin, XIE Gege, NIU Zhongen,   et al. 人类活动和气候变化对锡林郭勒草原生产力影响 闫慧敏，谢格格，牛忠恩，等 DOI: 10.5814/j.issn.1674-764x.2024.05.003 Abstract: Natural grasslands are increasingly subjected to the dual stresses of grazing pressures and climate change. However, the contribution of human activities, especially grassland ecology conservation projects, to grassland improvement remains ambiguous. Utilizing MODIS satellite data in conjunction with the VPM model, the gross primary productivity (GPP) changes in the Xilingol grassland from 2000 to 2020 were assessed. Based on GPP data derived from remote sensing, this study quantitatively assessed the spatiotemporal dynamics of the impacts of climate change and human activities on the productivity of grassland in the Xilingol League. From 2000 to 2020, the grasslands exhibited a greening t ………………………………
