1 前言我们对大气组成如何影响气候的了解还很肤浅。但是,不断积累的知识表明:CO_2和其它人为的多元气体浓度的上升将大大地提高全球的平均温度。随着全球变暖,平均温度、冷热周期的分布以及许多其它化学指标和物理参数,如降雨量、蒸发、海平面、土壤和水分的化学特性也将出现地区性或局部的变化。本文探讨了这些变化对温带森林,包括
1 Preface We are still a superficial understanding of how the composition of the atmosphere affects the climate. However, the accumulated knowledge suggests that an increase in the concentration of CO 2 and other anthropogenic multivariate gases will greatly increase the average global temperature. As the global warming, the average temperature, the distribution of hot and cold cycles and many other chemical indicators and physical parameters, such as rainfall, evaporation, sea level, soil and water chemical characteristics will also be a regional or local changes. This paper explores these changes to temperate forests, including
