对北京山区落叶阔叶林辽东栎蒸腾速率进行了一个生长季的连续测定 ,结果表明影响其蒸腾速率的因子主要是气孔阻力、太阳辐射强度、叶面温度、叶室温度、大气相对湿度 .对辽东栎叶片气孔阻力和蒸腾速率相关关系的分析结果显示 ,蒸腾速率和气孔阻力间属非线性关系 ,其方程为 :Tr辽东栎 =10 .0 - 4 .7ln(Rt) .
Successive determination of transpiration rate of Quercus liaotungensis decidues in deciduous broad-leaved forests in Beijing mountainous area showed that the factors influencing transpiration rate were stomatal resistance, solar radiation intensity, leaf temperature, leaf temperature and relative humidity. The results of correlation analysis between stomatal resistance and transpiration rate of Quercus liaotungensis showed that there was a non-linear relationship between transpiration rate and stomatal resistance, and the equation was: Tr Quercus liaotungensis = 10 .0-4.77n (Rt).
