Abstract: Global climate change, with elevated CO2 concentration and temperature rise as the two major indicators, has great impact on crop water use efficiency. Study of the characteristic and mechanism of the response of crop water use efficiency to elevated CO2 concentration and temperature rise is of great significance to revealing the mechanism of how climate change impacts crop production. This paper presents the research progress on the responses of crop water use efficiency to elevated CO2 concentration and temperature rise, the synergistic effect of elevated CO2 concentration and temperature rise, and methods of the research. In addition, this paper points out the key issues that need to be resolved in the future, including: (1) synergistic effect of multi-factors, (2) differences in the responses of different species, (3) response processes at different levels of scale, and (4) adaptability of crop water use efficiency to climate change.

Key words: CO2 concentration, crop water use efficiency, response, temperature
