摘　　要：柽柳属(Tamarix)植物起源于第三纪古地中海地区,具有耐盐碱、抗干旱和抗沙埋等特点,适应性强,是沙荒地和盐碱地的建群种。从植物生理生态和分子机理上阐述了柽柳属植物适应广泛生境的机制,包括种群特征、个体形态结构、种子繁殖特性、群体遗传结构以及植株在干旱和盐碱胁迫下生理生化和分子响应等,综述了其在生态和药用方面的价值,并提出可深入研究的问题和方向。The plant of the genus Tamarix was an Old World genus occurred in Mediterranean region since Tertiary.As constructive species on the sandy and salty soil,they played important roles in sandy fixation and fragile ecosystem restoration.From the views of eco-physiological and molecular levels,this paper reviewed the mechanism of the adaptation of diverse habitats,including the aspects of community character,morphology,seed propagation,genetic variation.By summarizing their physiological,biochemical and molecular response under drought and saline-alkali stress,the paper re-evaluated its roles in ecological restoration,medicine and health.The aim of this review was to propose the issues and directions in the further studies and to provide theoretical references for research and utilization of Tamarix plant.
