太原武宿机场春季草丛昆虫和土壤动物的调查

2006年3月～5月份对太原武宿机场草丛昆虫和土壤动物种群及生物量进行了研究.结果表明,机场生态系统中草丛昆虫种群和土壤动物种群的综合指标偏低.本次调查共获标本778只,属2门3纲,共10类群.其中蜱螨目、弹尾目和膜翅目为优势类群;蜘蛛目、鞘翅目、蚯蚓、多足纲、直翅目和等足目为常见类群.草地生境及草丛动物的分布是吸引鸟类在机场栖息和摄食的主要原因.因此研究该生境下的昆虫、土壤动物的种类及生物量对于机场鸟类的控制有直接而重要的意义.

Investigation on the Insects and Soil Fauna of Taiyuan Wusu Airport Grassland in Spring

Through ecological investigation from March to May in 2006,the population and biomass of insects and soil fauna were examined in Wusu airport grassland,Taiyuan.The results indicated that there is low comprehensive indicator of the population insects and soil fauna in Wusu airport.The research showed that a total of 778 insects and soil fauna were observed,which belonged to 2 phyla,3 classes and 10 groups.The dominant groups were Acarina,Collembola and Hymenoptera;and the common groups were Araneida,Coleoptera,Earthwarm,Myriapoda,Orthoptera and Isopoda.Therefore the main reasons for birds to stay in airport grassland were grassland circumstances and insects and soil fauna.Investigating the population and biomass of the insects and soil fauna communities is very important to control and decrease the number of birds around airport.
