摘　　要：中国引种优良的荒漠化和盐碱地治理树种四翅滨藜已有20多年时间。本文从形态特征及生理生态学的角度对国内外相关研究成果进行了综述,主要包括四翅滨藜的地域分布,适宜引种区划分,形态分类、外部形态特征、叶片解剖结构,种子耐盐性试验,以及在不同程度的盐碱、干旱、低温非生物胁迫下生理生化指标的变化,抗逆性机理,生物干扰、自然演替及生物多样性等研究,并分析了进一步研究的问题,以期对退化生态系统的恢复及其开发利用提供科学依据。Atriplex canescens （ Nutt. ） has been introduced irom America into China to control de sertification and salinification for more than twenty years. From the view of morphological charac teristics and physiological ecology, this paper reviewed the research achievements in the introduc tion of A. conescens at home and abroad, with the focus on the regional distribution, proper areas division, morphological classification, external morphological characteristics, leaf anatomical structure, seed salt resistance, variations of physiological and biochemical indices under different degrees of abiotic stresses such as salinity, drought, and low temperature, resistant mechanisms, biological interference, natural succession, and biological diversity. The issues needed to be fur ther studied were also analyzed. The aim of this review was to provide references for the rehabili tation of degraded ecosystems.
