论述了青藏高原植被净初级生产力（NPP）的空间分布和时间变化动态，以及NPP与气候因子的关系和对未来气候变化的响应。总结出了以下结论：①青藏高原年均 NPP为0．3 Pg Ca-1，由东南向西北逐渐递减，与该地区的水热条件和植被类型的地带性分异规律一致；②近年来，青藏高原的植被生产力在波动中呈上升趋势，年增加速率约为0．7％；③温度是影响青藏高原生物生长的主导因子，青藏高原净初级生产力随着气温和降水的增加而增加；④未来气候变化影响青藏高原植被NPP ，在IPCC预测的B1、A1B和A2气候变化情景下，青藏高原的N PP均呈增加的趋势。

This study reviews the spatial distribution and temporal dynamics of vegetation net primary productivity (NPP) on the Qinghai-Tibetan Plateau ,and also discusses the relationships between NPP and climatic factors and the responses of NPP to future climate change .The results show that :① The mean annual NPP of the Qinghai -Tibetan Plateau vegetation is 0 .3 Pg Ca-1 ,with NPP clearly decreasing from southeast to northwest ,consistent with the changes in the vegetation zone and precipitation and temperature patterns ;② The annual NPP of the plateau shows obvious increasing trends .In general ,the NPP has increased at an annual rate of 0 .7% ;③Temperature is the dominant factor affecting NPP .Furthermore ,NPP increases with increasing temperature and precipitation in this region ;④ If future climate change continues , the vegetation NPP of the Qinghai - Tibetan Plateau will change accordingly .In addition ,the NPP shows an increasing trend under IPCC B1 ,A1B and A2 climate change scenarios .
