Abstract: The alpine meadow ecosystem on Qinghai-Tibetan Plateau has been degrading in -recent- years. Based on the long-term observation data about boveground net primary productivity, yearly precipitation, yearly mean air temperature, and the mean precipitation and air temperature in growth season collected from Haibei Alpine Meadow Ecosystem Research Station, this paper assessed the restoration capability of alpine meadow ecosystem in Haibei Area of Qinghai-Tibetan Plateau， aimed to provide scientific information and suggestions to sustain the development of alpine meadow ecosystem in this area. The results indicated that the aboveground net primary productivity of the ecosystem was more related to the dynamic changes of precipitation and temperature. The effect of precipitation and temperature on the net primary productivity was obvious only in present year, but not in the following years. Therefore, the alpine meadow ecosystem appears to have a higher restoration capability. By comparing the restoration capability between the alpine meadow ecosystem in study area and the four natural ecosystems in Israel and South Africa, it was found that the alpine meadow ecosystem was superior to the four natural ecosystems. To-sustain-the alpine meadow ecosystem, it is important to utilize the alpine grassland resources efficiently and to restore the degraded grassland timely.
