摘　　要：利用网捕法、灯诱法等方法采集阿勒锦岛国家湿地公园草甸、灌丛、林地3种生境的昆虫样本,分析其昆虫群落结构、生物多样性指数随时间推移的变化以及与环境因子的关系。结果表明:采集昆虫经鉴定隶属于9目74科209种,昆虫群落组成丰富,优势类群为鳞翅目、鞘翅目。其昆虫物种数、个体数量的变化均受时间的影响,各生境昆虫物种个体数量在6—8月达到最高。草甸生境香浓多样性指数、优势度指数在7月最高,均匀度指数变化较为稳定。典范对应分析表明植物生物量、盖度与昆虫群落分布密切相关。Insect community structure and biodiversity index were collected from meadow,shrub and woodland in Alejin Island National Wetland Park by using net traps and light traps to analyze the changes of insect community structure and biodiversity index over time and their relationship with environmental factors.The collected insects belonged to 9 orders,74 families and 209 species,and the insect community composition was rich.The dominant insect species were Lepidoptera and Coleoptera.The changes of insect species and individual number were affected by time,and the individual number of insect species in each habitat reached the highest from June to August.The diversity index and dominance index of meadow habitat were the highest in July,and the evenness index of meadow were stably.CCA analysis showed that coverage and plant biomass were closely related to insect community distribution.
