| 摘 要： | 文章提出了沙被的概念和定义,即:沙物质在地表积聚形成的覆被。阐述了依据沙被所处的气候区与植被区、沙被形态、颜色、有无植被、位于表层还是下层等特征的沙被分类方式。同时,指出了沙被的水平结构和从沙被边缘到中心其形态变化、植被变化的规律,研究和探讨了沙被的生态效应、与植被、风的关系和沙被的动态变化特点,以及沙被生态系统的保护修复与开发利用的原则。

| Abstract: | The paper puts forward the concept and definition of sand cover.The sand cover is formed by the accumulation of sand material on the surface.The classification of sand cover is described according to its climate zone and vegetation zone,its shape,color,vegetation,surface or lower layer,and other characteristics.At the same time,the paper points out the horizontal structure of the sand cover and the rules of its morphological change and vegetation change from the edge of the sand cover to the center.The ecological effect of the sand cover,the relationship with vegetation and wind,the dynamic change characteristics of the sand cover,and principles of conservation,restoration,development and utilization of sand ecosystem are researched and discussed. |
