荒漠沙生植物生理生态学研究与展望

荒漠沙生植物是在极端干旱、贫瘠、强风沙流等条件下生长发育的一些植物种类，它们不仅具有较强的抗逆能力，而且在其脆弱生态系统稳定性的维持和受损生态系统的恢复重建中起着重要的作用。有关荒漠沙生植物生理生态特性的研究早在上世纪初即已开始，随着测试手段和测定方法的不断改进，近年来取得了不少研究成果。但是随着植物逆境生理生态在宏观和微观方面研究的不断深入和生态环境建设的需求，迫切需要加强沙生植物生理生态研究的深度和研究的系统性。本文就沙生植物生理生态的研究历史、现状及国内外有关植物抗逆生理生态研究进展作了简要综述，并对今后沙生植物生理生态学的研究方向提出了一些初步建议。

Current Status and Perspective of Eco-physiological Researches in Psammophytes

Desert psammophyts are plants living in extremely dry habitats with poor soil and strong wind. They not only have high capacity of anti_adversity, but also play a very important role in sustainning the stability of fragile ecosystems and the restoration of degraded ecosytems. Researches in the eco_physiological characteristics of psammophytes started as early as the beginning of the last century, and a great amount of acheivments have been obtained resently with the consistent improvement of research methods and equipment. With the development of research in eco_physiology of plants in adverse environment, and the need of environmental protection or reconstruction,it is pressingly necessary to enhance the eco_physiological research in desert psammophytes, in depth and systematically. The history, current status and advances of the reseaches in anti_adversity eco_physiology of plants are briefly reviewed, and perspectives and suggestions are presented in this article.
