在2016年~2017年6月~10月期间对升金湖湿地昆虫多样性进行调查,在不同月份对该湿地的昆虫种类及数量进行了统计,对采集的物种进行编目,并采用Shannon-Wiener物种多样性指数、Pielou均匀度指数、Simpson优势度指数、Margalef丰富度指数对其群落多样性进行分析。结果表明:升金湖湿地共有昆虫种类367种,分别隶属于15目112科。其中优势类群为半翅目、直翅目和鞘翅目,其所占比例分别为34.77%、19.59%、19.09%。不同月份多样性指数高低顺序为6月 > 7月 > 8月 > 9月 > 10月。多样性、均匀度及丰富度的相关分析说明:升金湖湿地昆虫多样性指数与丰富度、均匀度指数呈正相关,表明该湿地昆虫群落较为稳定。通过Jaccard相似性系数分析,升金湖湿地昆虫群落与邻近的菜子湖呈现较显著的差异,推测因地形差异、植物类群差异和气候条件等因素影响所致。 The insect diversity of Shengjin Lake wetland was investigated from June to October 2016~2017. The species and quantity of insects in the wetland were counted in different months. The collected species were catalogued. The Shannon-Wiener species diversity index, Pielou evenness index, Simpson dominance index and Margalef abundance were used to analyze community diversity. The results showed that there were 367 species of insects belonging to 15 orders and 112 families in Jinhu wetland. The dominant groups were Hemiptera, Orthoptera and Coleoptera, accounting for 34.77%, 19.59% and 19.09% respectively. The order of diversity index in different months is June > July > August > September > October. Correlation analysis of diversity, evenness and richness showed that insect diversity index was positively correlated with richness and evenness index, indicating that insect community in Shengjin Lake wetland was relatively stable. Jaccard similarity coefficient analysis showed that the insect community in Shengjin Lake wetland was significantly different from that in the adjacent Caizi Lake. It was speculated that the insect community in Shengjin Lake wetland was influenced by topographic differences, plant species differences and climatic conditions.
