摘　　要：桦树是三江湿地自然保护区内的主要树种,也是三江湿地生态系统的重要组成。利用捕虫器在5~9月对桦树林样地进行捕捉采集,并带回实验室整理和鉴定。初步统计,5个月共采集标本9 104号,分属于9目,共59种。其中,膜翅目昆虫和双翅目昆虫为每个季节的优势目,长翅目和蜻蜓目昆虫数量最少,为稀有目。在桦树林的昆虫群落中,昆虫种群数量,多样性指数受季节影响显著,各个多样性指数在5月份最低,9月份达到峰值。Birch is not only the main tree species in Sanjiang Wetland Nature Reserve, but also an important component of Sanjiang wetland ecosystem. The birch forest sample plot was captured and collected by insect catcher from May to September,and brought back to the laboratory for sorting and identification.According to preliminary statistics, 9 104 samples were collected in five months, belonging to 9 orders and 59 species. Among them,Hymenoptera and Diptera are the dominant orders in each season,and longoptera and Odonata are the least, which are rare orders. In the insect community of birch forest, the number of insect population and diversity index are significantly affected by seasons.Each diversity index is the lowest in May and reaches the peak in September.
