Abstract	植被物候现象是环境条件季节和年际变化最直观、最敏感的综合指示器。野外目视观察法、植物物候模型、数字相机技术、遥感技术等是物候监测的主要方法。青藏高原整体上高寒草地返青期变化目前有4种观点,返青期推后、提前、没有明显变化、在波动中提前。物候与气候之间相互关联,相互作用。温度、水分、CO_2浓度、积雪和极端气候是影响高寒草地生长发育的重要因素。不同尺度下物候变化及哪个因素更具影响力存在不确定性。最后还展望了未来研究重点方向。
Other Abstract	Vegetation phenology is the most intuitive and sensitive indicator of seasonal and inter-annual variability under environment conditions.The phenology monitoring methods mainly include field observation, phenology model,digital camera and remote sensing technology.On the Tibetan Plateau,the start of growing season for alpine grassland had four viewpoints:experiencing an advancing and advancing in fluctuating trend,apostponing trend and no change,respectively.Phenology phases experience interactions with climatic factors.These factors,such as temperature,precipitation,CO_2 concentration,snow cover and extreme climate,play an important role in alpine grassland growth.Meanwhile,phenology changes at different scales and the driving factors are uncertainty.Finally,the existing problems and the future research directions were discussed.
