英文摘要	Global environmental change is rapidly altering the dynamics of terrestrial vegetation, with consequences for the functioning of the Earth system and provision of ecosystem services(1,2). Yet how global vegetation is responding to the changing environment is not well established. Here we use three long-term satellite leaf area index (LAI) records and ten global ecosystem models to investigate four key drivers of LAI trends during 1982-2009. We show a persistent and widespread increase of growing season integrated LAI (greening) over 25% to 50% of the global vegetated area, whereas less than 4% of the globe shows decreasing LAI (browning). Factorial simulations with multiple global ecosystem models suggest that CO2 fertilization effects explain 70% of the observed greening trend, followed by nitrogen deposition (9%), climate change (8%) and land cover change (LCC) (4%). CO2 fertilization effects explain most of the greening trends in the tropics, whereas climate change resulted in greening of the high latitudes and the Tibetan Plateau. LCC contributed most to the regional greening observed in southeast China and the eastern United States. The regional effects of unexplained factors suggest that the next generation of ecosystem models will need to explore the impacts of forest demography, differences in regional management intensities for cropland and pastures, and other emerging productivity constraints such as phosphorus availability.; Strategic Priority Research Program of the Chinese Academy of Sciences [XDB03030404]; National Basic Research Program of China [2013CB956303]; National Natural Science Foundation of China [41530528]; 111 Project [B14001]; European Research Council [ERC-SyG-610028 IMBALANCE-P]; NASA Earth Science; Australian Climate Change Science Program; EC FP7 grant LUC4C [603542]; EC FP7 grant EMBRACE [282672]; Helmholtz Association ATMO programme; CSIRO; ERTDF from Ministry of Environment, Japan; US Department of Energy (DOE), Office of Science, Biological and Environmental Research; DOE [DE-AC05-00OR22725]; Swiss National Science Foundation; FP7 funding through project EMBRACE [282672]; SCI(E); SSCI; ARTICLE; slpiao@pku.edu.cn; 8; 791-+; 6
