甘肃盐池湾国家级自然保护区昆虫类群组成、区系分布及其与植被类型关系研究

Faunal Distribution and Group Composition of Insect and its Relationship with Vegetation Types in Yanchiwan National Nature Reserve of Gansu Province

为了查清甘肃盐池湾国家级自然保护区内昆虫种类组成及昆虫区系特征,采用实地踏查和样点调查相结合的方法,对样方内和踏查线路中出现的所有昆虫个体均采集标本并鉴定,统计昆虫种类,确定其目、科、属的区系地理成分。结果表明:分布于该保护区的昆虫有7目25科61属88种。保护区最多是鳞翅目、鞘翅目和直翅目昆虫,其科、属和种数分别占全部科、属和种数的28.00%、45.90%和44.31%,32.00%、21.31%和18.18%,12.00%、11.47%和19.32%,其他目的属数和种数占比都小于10%。

In order to find out the group&fauna characteristics of insect in the Yanchiwan National Nature Reserve in Gansu Province,a combination of on-site tracing&sample survey is used to detect all insects in the sample and in the tracing route.Collect specimens&identify,count the species of insects,and determine the geographical components of the fauna of the order,family,and genus.The insects distributed in the protected area have 7 orders,25 families,61 genera&88 species.The protected areas are at most Lepidoptera,Coleoptera&Orthoptera,whose families,genera&species constitute(28.00%,45.90%&44.31%),(32.00%,21.31%&18.18%),(12.00%,11.47&19.32%)of all the families,genera&species.The ratios of the genera and species of other orders are less than 10%.
