a, b Comparison of the response relationship between the trends of EWUE, IWUE and uWUE and trends of climate factors at the significant vs. non-significant sites. The marks above or below the bars indicate the significance of the regression: + indicates p < 0.1, * indicates p < 0.05, ** indicates p < 0.01, and *** indicates p < 0.001; c, d The relative importance of atmospheric CO2 concentration (Ca) and meteorological factors in influencing WUE at the significant and non-significant trend sites. The size of the circles represents the percentage of the variance that is explained by the independent variable, and the intensity of the color represents its importance
