中文摘要：

近年来随着人口增长、过度放牧以及自然因素的影响,致使浑善达克沙地荒漠化进程加速。现基于浑善达克沙地不同坡向和沙丘高度的微地形类型,对当地乔灌木植被进行调查分析,旨在为当地人工植被配置提出建议。结果表明：背风坡植被种类优于迎风坡;沙丘高度对植被的生长分布具有一定的影响;无论是迎风坡还是背风坡,榆树均占据十分重要的地位,具有不可替代的作用,是该地区的建群种。建议迎风坡植被配置模式为榆树＋小叶锦鸡儿＋黄柳＋虫实;背风坡植被配置模式为榆树＋黄柳＋砂生桦＋羊草＋狗尾草。

英文摘要：

In recent years as the population grows,overgrazing and the influence of natural factors,make the desertification process accelerated of Hunshadake Sandy Land,based on different micro-landform types of slope aspect and dune height in Hunshadake Sandy Land,analyzed local vegetation and shrubs,aimed to make recommendations for local configuration artificial vegetation.The results showed that vegetation types of leeward slope were more than windward slope;dune height had a certain influence on the growth of vegetation distribution;whether windward or leeward,elm occupies a very important position,had an irreplaceable role,and was constructive species in the region.Finally,following recommendations were put forward：windward vegetation configuration mode was Ulmus pumil＋Caragana microphylla＋Salix gordejevii＋Corispermum hyssopifolium;leeward vegetation configuration mode was Ulmus pumil＋Salix gordejevii＋Betula gmelinii＋Leymus chinensis＋Setaria viridis.
