中文摘要	以流动沙丘丘间低地过渡带为研究对象,研究了不同生态组群植物侵入迎风坡过渡带的时间顺序,分析了过渡带变化对流动沙丘丘间低地单元植被格局的影响。结果表明:(1)流动沙丘区的沙埋导致背风坡过渡带部分沼泽草甸植物退出丘间低地,风蚀导致典型沙生植物侵入迎风坡过渡带,从而在丘间低地呈现出一种特有的植被空间动态变化过程;(2)芦苇和黄柳对于迎风坡过渡带植被恢复的作用大于沙蓬和乌丹蒿;(3)流动沙丘迎风坡丘间低地过渡带植物种类比流动沙丘的多、但远比丘间低地少,具有流动沙丘区特有的边缘效应。
英文摘要	We studied the transition zones between active sand dunes and interdune lowlands, chronological orders that the plants of different ecological groups invaded transition zones between windward slopes of active sand dunes, and the effects of transition zone ’s dynamics on vegetation patterns in active dune-interdune lowlands.The sand burial of active sand dunes leaded to the disappearing of parts of limnocryptophyte-meadow plants from interdune lowlands, eolian erosion of active sand dunes resulted in the invading of psammophytes into transition zones between windward slopes of active sand dunes and interdune lowlands with a typical vegetation succession in active sand dune fields.The roles of Phragmites communis and Salix gordejevii to revegetations of active sand dunes were more than those of Agriophyllum sqau rrosum and Artemisia wudanica.The plant species of transition zones between windward slopes of active sand dunes and interdune lowlands were more than those of active sand dunes, greatly fewer than those of interdune lowlands with a typical edge effect in active sand dune fields.
