摘　　要：2020年5月至9月,采用随机取样和系统取样相结合的方法,对成都市的白鹤滩国家湿地公园、白鹭湾湿地公园、香城湿地生态公园、青龙湖湿地公园和南湖湿地公园中的昆虫群落组成、结构和生物多样性进行了调查和分析。研究结果表明,在6座湿地公园中,共采集昆虫样本9993号,记录了16目141科486种昆虫,半翅目、鞘翅目、鳞翅目、双翅目、蜻蜓目、直翅目和膜翅目昆虫为优势类群;桤木河湿地公园和白鹤滩国家湿地公园中昆虫群落的多样性水平较高,昆虫群落结构复杂;在6座湿地公园中,植食性昆虫的科、物种和个体数量都远大于捕食性昆虫、中性昆虫、寄生性昆虫;只有少数湿地公园中的植食性昆虫与捕食性昆虫的个体数量之间、植食性昆虫与寄生性昆虫物种数量之间和个体数量之间存在显著的正相关关系。From May to September 2020,a combination method of random sampling and systematic sampling was used to study insects in Baihetan National Wetland Park,Qimuhe River Wetland Park,Bailuwan Wetland Park,Xiangcheng Wetland Ecological Park,Qinglong Lake Wetland Park and Nanhu Wetland Park in Chengdu city.Composition and biodiversity of insect communities in 6 wetland parks were investigated and analyzed.The research results showed that in the 6 wetland parks,a total of 9993 insect samples were collected,and 486 insect species of 141 families in 16 orders were recorded,including Hemiptera,Coleoptera,Lepidoptera,Diptera,Odonata,Orthoptera and Hymenoptera insects were the dominant groups.The diversities of insect communities in Qimuhe River Wetland Park and Baihetan National Wetland Park were relatively higher,and the structures of insect communities were complex.In the 6 wetland parks,the families,species and individual numbers of herbivorous insects were much larger than those of predatory insects,neutral insects,and parasitic insects.There were significant positive correlation relationships between individual number of herbivorous insects and that of predator insects,between species number of herbivorous insects and that of parasitic insect,between individual number of herbivorous insects and that of parasitic insect.
