干旱河谷10种生态恢复树种的光合和水分生理特征研究

Research on Photosynthetic and Water Physiological Characteristics of 10 Tree Species Used for Ecological Restoration in Dry Valleys

摘要: 通过对岷江上游干旱河谷10种生态恢复树种盆栽苗木的光合、荧光以及水分生理特征等的比较，分析了不同植物在干旱地区的光合运作情况以及光合生理特征和水分生理特征，及其间的相关关系，揭示了各类植物的抗旱特征，以期为干旱河谷区植被恢复树种材料的选择提供理论依据。

Abstract: In order to provide theoretical basis of tree selection for vegetation restoration, 10 tree species were chosen for measuring and comparing their photosynthetic, Chlorophyll fluorescence and water physiological characteristics in the dry valley of the Minjiang River. The result revealed the drought resistance characteristics of various plants by analyzing the photosynthetic operation, photosynthetic physiological characteristics, water physiological characteristics and correlations of different plants in arid regions.
