摘　　要：基于准噶尔盆地南缘荒漠植被样方的调查资料,从不同类型群落的物种多样性及其与生境的关系等方面对该区域植被分布现状进行了分析,并且用相似性系数对不同类型群落采取的沙漠化防治措施的可行性进行了探讨。结果表明:调查区内主要分布着20种荒漠植物,无乔木,只有灌木和草本植物;采取人工补植的方式恢复荒漠植被宜在距离沙漠较远的区域进行;在远离居民生活区的区域布设围栏生态效果不明显;三芒草适于作为沙丘植被恢复的先锋物种。Based on desert vegetation survey in the southern edge of Junggar Basin,vegetation distribution of the status quo in the region was analyzed from the relationship between different types of species communities and habitat,and we also explored the feasibility of desertification prevention and control measures will be in taken to different types of communities with similarity coefficient.The results showed that there were 20 kinds of main desert plants in the area,no trees,only shrubs and herbaceous plants;The way to restore desert vegetation by artificial replanting was more appropriate in the desert far away from the region;Laiding fence far away from the living zones had not obvious ecological effects;Aristida adscensionis was suitable as a pioneer species in the restoration of sand dune vegetation.
