摘要： 全球变化导致青藏高原腹地气候的暖干化趋势,也引起该区高寒草甸植被向高寒草原植被的退化。研究区内为高寒草甸一高寒草原过渡区,高寒草甸植被的退化速率为14.2km/10a,而相应地在退化区内生物总量亦呈下降趋势。气候暖干化是引起高原腹地植被退化的原因。而植被退化与区域生物总量的下降将成为影响该区环境自调能力和牧业经济发展的消极因素。

Abstract: Global warming caused a dryer and warmer climate in the hinterland of the Qinghai-Tibet Plateau.Does it cause any responses from the plants ecology,and how?Based on field works and statistical data collected in 2002 and 2003,we basically concluded warming trend of the climate is the major reason for the succession devolution of alpine plants in the central part of the plateau.In the study area,it is specially causing a devolution from alpine Kobresia meadow to Alpine Stipa steppe at a rate of 14.2km/10a.Accordingly,the total biomass of the area is declining.With contrast to some relative researches,we basically concluded a dryer and warmer climate should take the responsibility for vegetation devolution accompanied with biomass decline in the area.Changes of the surface vegetation will be the negative factors influencing the capability of the environment self-adjustment and the development of the local economy.

Key words: global warming, hinterland of Qinghai-Tibet Plateau, warming trend, grassland resources
