摘要
2011—2013年的5月~9月，采用大面积随机调查法对吉林省西部地区蜻蜓目昆虫资源进行了系统调查，共获得9科28属47种蜻蜓目昆虫。其中，春蜓科、蜻科、蟌科和丝蟌科为吉林省西部地区蜻蜓目昆虫的优势类群；蜻科中赤蜻属的物种数量和个体数量最多；春蜓科中，棘伟春蜓属的物种数量和个体数量最多；蟌科中，异痣蟌属的物种数量和个体数量最多；丝蟌科中，各属的物种数量和个体数量相当。蜻蜓目昆虫多样性指数在春季随着气温升高、营养级丰富而呈现出明显的上升趋势，在7月达到最高值，以后出现下降趋势；均匀性指数总体趋势变化不大；优势集中性指数5月最高，以后出现小幅波动。
The resources of Odonata in the west of Jilin Province were invested randomly from May 2011 to September 2013. There were 47 species of dragonfly,which belong to 9 families and 28 genera,among which, Gomphidae,Libellulidae,Coenagrionidae and Lestidae were dominant species in west of Jilin. The individuals and species number of Sympetrum were the most abundant in Libellulidae,Trigomphus are the most in Gomphidae, Ischnura is the most in Coenagrionidae, but the individuals and species number had no significant difference among genera in Lestidae. Diversity index of dragonfly showed an obvious rising trend with temperature rising and richness of nutrition levels in Spring,and reached the peak in July,and then diversity index decreased. Evenness index wasn’ t changed greatly,the dominant concentration index was appeared in May and had a slight fluctuation later.
