| 摘 要： | 对黄土高原半干旱区侧柏和臭椿的光合、蒸腾特性进行了系统的研究,并对光合速率、蒸腾速率、气孔导度、水分利用率和胞间CO2浓度进行了分析,结果表明:臭椿的日蒸腾速率、日光合速率、水分利用效率和气孔导度均高于侧柏;臭椿和侧柏的胞间CO2浓度都随着光合速率的变化而变化,光合速率高则胞间CO2浓度较低,反之则较高,侧柏和臭椿在长期适应环境的过程中产生了不同的生理生态对策.

| Abstract: | The transpiration,photosynthesis of Platycladus orientalis and Ailanthus altissima in the semi-arid region of the Loess Plateau were studied.The Pn,E,Gs,WUE and Ci were analyzed.The result showed that the average Pn,E,WUE and Gs of Ailanthus altissima were higher than that of Platycladus orientalis;The Ci of Platycladus orientalis and Ailanthus altissima were changed by the change of Pn,the higher of Pn with lower Ci,on the contrary was higher.They have established different ecological strategy to adapt the environment. |
