Abstract: Alpine grassland ecosystems on Tibetan Plateau are highly sensitive to climate change. How these ecosystems response to climate change is a great concern. Based on the past five years researches, this paper briefly reviewed the responses of these ecosystems to climate change from the aspects of phenology, plant productivity, and carbon cycle, and the adaptive management to climate change. There are inconsistent conclusions so far. Most of the researches indicated that warming advanced the plant phenology and increased the primary productivity of alpine meadow, while opposite trends were observed for alpine steppe, suggesting that different plant communities in different regions could have different modes in response to the temperature change in different seasons. Similarly, there are controversial conclusions about the responses of plant species diversity and carbon sink/source to climate change because of the differences in spatial and temporal scales and research methods. Therefore, further researches are needed to integrate the spatial and temporal researches and to strengthen the studies of ecological processes and mechanisms.
