全球变化的生态系统适应性

ADAPTATION OF TERRESTRIAL ECOSYSTEMS TO GLOBAL CHANGE

全球变化的适应性研究已经成为全球变化研究的重点,亦是制定全球变化适应对策的关键。基于全球变化的定义,从生态系统对全球变化适应的4个方面:①对大气CO2浓度变化的适应性;②对气候变化的适应性;③对CO2浓度与气候变化协同作用的适应性;④对人为干扰的适应性,综述了当前的研究成果,进而提出了未来关于全球变化的生态系统适应性研究需要重视的方面,尤其是关于生态系统对全球变化响应的阈值研究应引起高度重视。

Adaptation of terrestrial ecosystems to global change has become a key issue of global change study and of countermeasures formulation for human being. The adaptation of terrestrial ecosystems to global change would be reviewed in this paper from four aspects, i.e., (1) changes of CO_2 concentrations in the atmosphere, (2) climatic change, (3) combined changes of CO_2 concentrations in the atmosphere and climatic change, and (4) human disturbance, in terms of the definition of global change. Based on the present research, some important tasks related to adaptation of terrestrial ecosystems to global change are suggested. Among them, the threshold assessment of adaptation practices should draw more and more attention in the future.
