英文摘要: Long time series of vegetation dynamics is one of the core study areas for evaluating terrestrial ecosystems, and it is meaningful in global change research. In this study, the characteristics of climate change and dynamics of vegetation were analyzed systematically on Tibetan Plateau (TP) from 1981 to 2010. The results show that: 1) The annual average temperature and annual precipitation of the Tibetan Plateau increased by 0.7 degrees C and 12.4 mm every 10 years during 1981 to 2010, respectively. It had a significant increasing trend in temperature and precipitation over the past 30 years, but it would be warming and drying in the west, and warming and humid in the most of eastern areas in the future. 2) The spatial distribution of NDVI had remarkable longitude zonality that presented a stairs type to continuously rise from west to east. 3) In overall, the ecological environment of vegetation on the TP in the recent 30 years has been improved in the most areas, but degraded in part of local areas. About 33.91% vegetation had no significant change, the restoration area of vegetation (36.81%) was greater than that of the degradation area (29.28%).
