中文摘要： 水洞沟湿地昆虫计11目84科182种。其中半翅目和双翅目昆虫个体数量和种数较多，占个体总数的60%以上。植食性昆虫较捕食性和中性昆虫多。昆虫物种丰富度较高，群落结构复杂且稳定，群落种-多度曲线符合对数正态分布。捕食性群落的优势度随季节变化较大，植食性和中性昆虫群落的优势度随季节变化基本一致。
英文摘要： Insects in the Shuidonggou wetlands were assigned to 11 orders, 84 families and 182 species. Individual and species of Hemiptera and Diptera were more numerous than those of other orders, accounting for more than 60% of the total number of individuals collected. Phytophagous insects were more abundant than predatory and neutral insects. Insect species richness was high, and the community structure complex and stable. The curve of species-abundance was consistent with the log-normal distribution. Dominance within the predatory community varied greatly with the seasons, and dominance in the phytophagous and neutral insect communities was basically consistent with the seasonal changes
