The considerable interest in detecting global vegetation changes based on satellite observations is increasing. However, studies rely on single indices to explore the driving mechanisms of the greening trend might exacerbate uncertainties of global ecosystem change. Thus, vegetation growth dynamics from various biophysical properties required to be monitored comprehensively. In this study, a consistent framework for evaluating vegetation growth trends was developed based on five widely used satellite‐derived products of MODIS Collection 6; the consistency in vegetation growth was mapped; and the factors that affected the consistency of vegetation growth were explored. The results showed that, during 2000‐2015, 45.6% of global vegetated area experienced inconsistent trends in vegetation greenness, cover and productivity, especially in evergreen broadleaf forests, grasslands, open shrublands, woody savannas and croplands. Only 5.4% of global vegetated area exhibited simultaneous trends in greenness, cover and productivity, and the inconsistent areas were expanding in the study period. Contradictory vegetation changes were mainly reflected in the opposite trends of vegetation greenness and productivity in evergreen broadleaf forests. Moreover, the inconsistency change was mainly manifested in the greenness‐dominated vegetation enhancement, without enhanced productivity. The increment difference between NPP and GPP also showed respiration losses greatly offset the effect of vegetation greenness or cover on productivity. This study provides integrated insights for understanding the inconsistency of vegetation structural and functional changes in the context of global greening.

在绿色，覆盖和生产力方面，全球近一半的植被都经历了不一致的植被增长

对基于卫星观测来检测全球植被变化的兴趣日益浓厚。然而，研究依靠单一指标来探索绿化趋势的驱动机制，可能会加剧全球生态系统变化的不确定性。因此，需要对来自各种生物物理特性的植被生长动态进行全面监测。在这项研究中，基于MODIS Collection 6的五种广泛使用的卫星衍生产品，开发了评估植被生长趋势的一致框架。绘制了植被生长的一致性图；并探讨了影响植被生长一致性的因素。结果表明，在2000-2015年期间，全球植被的45.6％经历了植被绿色度，覆盖率和生产力的不一致趋势，特别是在常绿阔叶林，草原，开放灌木丛，木质大草原和农田中。在研究期间，全球仅有5.4％的植被面积同时呈现绿色，覆盖和生产力变化趋势，不一致的区域正在扩大。矛盾的植被变化主要反映在常绿阔叶林中植被绿色度和生产力的相反趋势。此外，不一致的变化主要表现在以绿色为主的植被增强中，而没有提高生产力。NPP和GPP之间的增量差异也表明呼吸损失大大抵消了植被绿色度或覆盖度对生产力的影响。
