摘    要: 沙棘是半干旱地区用于水土保持造林的主要生态经济型树种,在中国特别是“三北”地区生态环境建设中发挥着日益重要的作用。为全面认识沙棘林的水土保持功能,掌握其水土保持作用的机制和条件,基于国内多年来在沙棘水文水土保持方面的研究成果,简要介绍我国沙棘资源发展现状,分析人工沙棘林发挥水土保持功能的特点,认为其水土保持作用机理主要依靠3个层次,即林冠层、枯枝落叶层和根系土壤层,并从沙棘林不同层次的水土保持作用机理及整体效益方面,综合评述国内最新的研究进展。在此基础上,提出了我国今后应继续加强研究的领域。

关 键 词:沙棘  水土保持  研究进展  机制  中国

Abstract:.Seabuckthorn is a main species of eco economical type for soil and water conservation afforestation in semi arid region of China and has played increasingly effect on eco environmental construction in the Northwest, Northeast and North of China. Based on the domestic research achievements, the developing of seabuckthorn resources in China has been introduced briefly, and the characteristics of function on soil and water conservation of planted seabuckthorn forest effect are analyzed. Function of Seabuckthorn forest depends on three layers of canopy, litter and soil root system to bring into playing soil and water conservation effect. The new research progress of seabuckthorn function on soil and water conservation have been reviewed from the aspects of canopy layer, litter layer, soil root system and the total benefits of seabuckthorn. Based on these, some research fields that should be strengthened to study in the future are put forward.
Keywords:seabuckthorn  soil and water conservation  research progress  mechanism  China
