自然植被

在全球增温条件下，自然植被NPP均有所增加，在湿润地区增加幅度较大，而在干旱及半干旱地区增加幅度较小。

The NPP of natural vegetation will increase more in moist area , and less in semiarid and arid areas .

在当前CO2浓度条件下，温度上升4℃导致的蒸散增加可使全样带自然植被的平均生物量和生产力分别下降32.1%和41.9%。

With CO2 remained unchanged and temperature increased by 4C , the induced increase in evapotranspiration could reduce the average biomass and net primary productivity ( NPP ) over the whole transect by 32.1 % and 41.9 % respectively .

aBP以来，人类干扰性植物成分的增加，表明人类活动对自然植被的影响改造作用增强，因此，本研究中气候的降温事件不排除人类影响的因素，仍需要进一步深入研究。

A BP , the increase in vegetation components disturbed by human being has demonstrated the intensified influence of human activities on the natural vegetation , so the influence of human activities on the cooling events remains to be further studied .
