中文摘要	查明古尔班通古特沙漠及交错带主要灌木白茎绢蒿和沙拐枣上节肢动物群落特征及发生规律,可为保护农田沙漠交错带白茎绢蒿及沙拐枣、合理利用沙漠及交错带节肢动物资源提供科学依据。本试验采用网捕法定时定点调查了古尔班通古特沙漠南缘沙漠及交错带白茎绢蒿与沙拐枣节肢动物的数量和种类。调查共捕获节肢动物677号,隶属于2纲10目22科。交错带生境白茎绢蒿及沙拐枣节肢动物群落物种丰富度、多样性指数均显著高于沙漠生境,优势度则反之。交错带生境天敌节肢动物数量显著高于沙漠生境。植食性节肢动物主要类群为蜡蝉总科、叶蝉科、蝗总科、盲蝽科、象甲科、蚜科;天敌节肢动物主要类群为小蜂总科、茧蜂科、姬蜂科、草蛉科和蜘蛛目。植食性节肢动物于5月中旬及7月上旬两次达到高峰,天敌节肢动物滞后于植食性节肢动物于5月下旬及7月中旬发生两次高峰。交错带白茎绢蒿与沙拐枣上天敌节肢动物资源丰富,大部分天敌节肢动物有一定的飞行能力,可转移至农田及沙漠生态系统,其生态意义重要。故提倡保护交错带白茎绢蒿及沙拐枣,防止过度放牧对生态系统造成严重影响。
英文摘要	The diversity and dynamics of arthropods on Seriphidium terraealbae and Calligonum leucocladum in southern marginal zone of Gurbanggut Desert was explored in order to protect S. terraealbae and C. leucocladum and provide reference for rationally using arthropods in ecotone. The fixed-point sampling method was used once a week in this research. The habitats were divided into desert and ecotone. A total of 677 specimens were collected, which belonged to 2 classes, 10 orders and 22 families. The species richness index and biodiversity index were significantly greater in ecotone than in desert. The dominance index was opposite. The individual number of natural enemy insects was significantly higher in ecotone than in desert. The main herbivore groups were Fulgoroidea,Cicadellidae,Acridoidea,Miridae,Curculionidae,and Aphididae ; the main natural enemy insects groups were Chalcidoidea,Braconidae,Ichneumonidae,Chrysopidae,and Araneida. The individual number of herbivore reached two peaks in middle of May and early July; the number of natural enemy insects reached two peaks behind the herbivore in late May and middle of July. The natural enemy insects were rich for S. terraealbae and C. leucocladum in ecotone,and most of them could fly and transfer to farmland and desert ecosystems as supplement, being important in the ecological significance. Accordingly, S. terraealbae and C. leucocladum should be protected from overgrazing in ecotone.
