图3. 叶片光合作用与污染物之间的关系。直线为通过显著性检验(p < 0.01)的回归线, 灰色阴影区域为95%的置信区间。AOD, 气溶胶光学厚度; AOT40, 超过40 nmol·mol-1的小时臭氧浓度累积量。
Fig. 3. Relationships between the photosynthesis of leaves and pollutants. The black line is the regression line for all data of the three sites (p < 0.01), and the gray areas is the 95% confidence band for the regression curve. AOD, aerosol optical depth; AOT40, accumulative concentration of ozone that more than 40 nmol·mol-1; Pn, photosynthetic rate.
