ADAPTATION OF TERRESTRIAL ECOSYSTEMS TO GLOBAL CHANGE

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.
