陆生植物气孔参数与大气CO_2浓度变化

陆生植物的起源与演化与全球气候和环境的变化密不可分,利用植物气孔参数(气孔密度和气孔指数)来指示或重建古大气CO2浓度变化是近年来全球变化研究的热点之一。就陆生植物气孔参数的研究进行了概述,对研究中存在的问题及其前景作了简要探讨,并对植物生物学方法在定量研究古气候和古环境变化的趋势进行了分析。

Relationship between stomata parameters of plants and atmospheric CO_2 concentration change

The origin and evolution of land plants are closely correlated with global climate and environment changes. Applying plant stomata parameters including stomata density and stomata index to reconstruct palaeo-atmospheric CO2 concentration changes has become a highlight in the field of global change in recent years. The progress of plant stomata parameters in the reconstruction of the palaeo-atmospheric CO2 concentration was summarized in this paper. Accordingly, the disputed problems and future trends of stomata parameters study were discussed. Furthermore, the progress of the quantitative reconstruction of palaeo- environment and palaeo-climate based on plants in recent years was also introduced in this paper.
