图8. 冠层气孔导度(GS)对水汽压亏缺的敏感性(-m)与水汽压亏缺(D) = 1 kPa时的GS (GSref)之间的比例变化。数值来自一个月数据子集的边界线拟合。对于每种方法组合, 线是最小二乘拟合(p < 0.001)。GS1: 直线和空心圆, GS2: 点划线和星号。
Fig. 8. Proportional increase of sensitivity of tree crown-level stomatal conductance (GS) to vapor pressure deficit (-m) with the conductance at vapor pressure deficit (D) = 1 kPa (GSref). Values are from boundary line fits of one month subsets of data. Lines are the least-square fit (p < 0.001) for each method combination. GS1, line and open circle; GS2, dash dot and asterisk
