description The invention discloses a vegetation change attribution evaluation method and device. According to the method, remote sensing vegetation index time series data and climate data are subjected to variable selection, time lag analysis, detrending processing, multiple regression residual analysis and contribution rate analysis so as to determine a regional scale vegetation change attribution evaluation result on the pixel level of the remote sensing image. Based on variable linear detrending processing, the co-trend effect of climatic factors and human activities is effectively removed, the confusion problem that the climatic factors and the human activities interfere with each other and jointly act on vegetation is avoided, and the vegetation change attribution evaluation method is high in stability and universality and can be applied to regional vegetation change attribution quantitative evaluation of different climatic regions and different vegetation types. 本发明公开一种植被变化归因评价方法及装置，该方法利用遥感植被指数时序数据和气候数据，通过变量选择、时滞分
