英文摘要	The Yellow River Basin (YRB) as a source of the oldest world cultures, flows through vast arid and semi-arid regions of China. Its fragile vegetation is suffering the obvious effect from regional climate change, and easily turns from a critical state into qualitatively different modes of change, which implies significant impacts on humans and ecosystems. Our results show that in the period of 1982-2015, the normalized difference vegetation index (NDVI) appeared significantly discontinuous changes by stagnant warming and strengthening wetting, especially in the central YRB (104.5 degrees-111 degrees E, 35.5 degrees-38 degrees N). The NDVI in this region shifted from slowly increasing (5.42 x 10-4 a-1) to rapidly increasing (5.13 x 10-3 a-1) around 2003, called the turning point (TP). Such shift change is mainly a result of increased moderate rain, with frequency trend changed from 0.083 times center dot a-1 to 0.324 times center dot a-1. Meanwhile, these changes on vegetation led to a reversal of the gross primary productivity (GPP) from decreasing to increasing. Such results indicated the vulnerable ecosystem of the central YRB has played a positive contribution to the carbon balance, and more sustainable management of vegetation is required for the ecological development and engaging adaptive strategy.
