摘要
本文对太原市汾河湿地公园、北中环桥北公园、大同路北中环街北绿化带的山楂访显花昆虫多样性进行了分析.山楂访显花昆虫分属于膜翅目的蜜蜂属以及双翅目的粗股蚜蝇属、管蚜蝇属和鼓额蚜蝇属,其丰富度为 5,目丰富度为 2,属丰富度为 4.山楂访显花昆虫的多度为 324,其中膜翅目的多度为 282,双翅目的多度为 42.山楂访显花昆虫的优势物种是西方蜜蜂和中华蜜蜂,大部分采样地西方蜜蜂的多度大于中华蜜蜂.山楂访显花昆虫多样性(目丰富度、属丰富度、种丰富度、Shannon-Wiener多样性指数、Simpson多样性指数)在汾河湿地公园、北中环桥北公园、大同路北中环街北绿化带之间差异不显著(P>0.05).
Abstract
The diversity of flower-visiting insects of Crataegus pinnatifida in Fenhe River Wetland Park,North Park of North Middle Ring Bridge,and north green belt of the intersection of Datong Road and North Middle Ring Street in Taiyuan City was analyzed in this paper.The insects belonged to genus Apis of order Hymenoptera and genus Syritta,Eristalis,Scaeva of order Diptera.The insect richness was 5,the order richness was 2,and the genus richness was 4.The abun-dance of insects was 324,the abundance of insects belonged to order Hymenoptera was 282,and the abundance of insects belonged to order Diptera was 42.The dominant species were Apis mellifera and Apis cerana.The abundance of Apis mellif-era was higher than that of Apis cerana in most sampling sites.There was no significant difference(P>0.05)in the insect diversity(order richness,genus richness,species richess,Shannon-Wiener diversity index,Simpson diversity index)in Fenhe River Wetland Park,North Park of North Middle Ring Bridge,and north green belt of the intersection of Datong Road and North Middle Ring Street.
