| 中文摘要 | the meadow ecosystem on the qinghai-tibetan plateau is considered to be sensitive to climate change. an understanding of the alpine meadow ecosystem is therefore important for predicting the response of ecosystems to climate change. in this study, we use the coefficients of variation (cv) and stability (e) obtained from the haibei alpine meadow ecosystem research station to characterize the ecosystem stability. the results suggest that the net primary production of the alpine meadow ecosystem was more stable (cv = 13.18%) than annual precipitation (cv = 16.55%) and annual mean air temperature (cv= 28.82%). the net primary production was insensitive to either the precipitation (e = 0.0782) or air temperature (e = 0.1113). in summary, the alpine meadow ecosystem on the qinghai-tibetan plateau is much stable. comparison of alpine meadow ecosystem stability with other five natural grassland ecosystems in israel and southern african indicates that the alpine meadow ecosystem on the qinghai-tibetan plateau is the most stable ecosystem. the alpine meadow ecosystem with relatively simple structure has high stability, which indicates that community stability is not only correlated with biodiversity and community complicity but also with environmental stability. an average oscillation cycles of 3-4 years existed in annual precipitation, annual mean air temperature, net primary production and the population size of consumers at the haibei natural ecosystem. the high stability of the alpine meadow ecosystem may be resulting also from the adaptation of the ecosystem to the alpine environment. |
