Abstract: Understanding how the dynamics of vegetation growth respond to climate change and human activities at different temporal and spatial scales is critical to project future ecosystem dynamics. At present, most of the studies mainly analyze the influence of climate change on vegetation, but there are few studies on the dual effects of climate change and human activities on vegetation. We systematically reviewed the methods of how to identify contributions of climate change and human activities on vegetation at quantitative aspects, including the qualitative and semi-quantitative assessment, regression analysis, residual trend method, and the first Net Primary Production based evaluation method. By summarizing and analyzing the progresses of previous researches on quantitative evaluation of the contributions and the existing problems, we found that it would be necessary to strengthen the study of disassembling the driving mechanisms of climate change and human activities on vegetation, as well as model evaluation and uncertainty analysis in the future.

Key words: climate change, anthropogenic activities, vegetation change, evaluation method
