摘　　要：为了解辽宁东部地区飞航蜘蛛的群落组成及特点,于2009年5—9月,采用吸虫塔对辽宁岫岩地区的飞航蜘蛛进行了调查。共采集蜘蛛标本549头,隶属于14科。对飞航蜘蛛的群落组成、时间动态、体型大小、发育阶段及性别比例等进行了分析。结果表明:辽宁东部地区飞航蜘蛛多样性丰富,皿蛛科(58.29%)和园蛛科(11.84%)是该地区飞航蜘蛛的优势类群;在成熟蜘蛛个体中,皿蛛科(74.02%)和肖蛸蛛科(11.02%)占有较大比例。蜘蛛飞航行为贯穿于整个调查时期,方差分析表明,8月上旬—9月上旬飞航蜘蛛的个体数量显著高于其他时期。飞航蜘蛛体型均<8mm,体长<3mm的达91.44%。χ2检验显示,飞航的幼蛛个体数量显著高于成蛛;而成蛛中,雄性个体数量显著高于雌性。Suction traps were used to investigate the community composition and its characteristics of ballooning spiders in Xiuyan Region of Liaoning Province, Northeast China from May to September 2009. A total of 549 specimens of ballooning spiders were captured, belonging to 14 families. The analysis of the community composition, seasonal dynamics, body lengths, phases growth , and sexual ratio of the specimens showed that the species richness of the ballooning spiders in east Liaoning was abundant, and Linyphiidae and Araneidae were the dominant groups, occupying 58.29% and 11.84%, respectively. In all mature individuals, the most abundant families were of Linyphiidae （74.02%） and Tetragnathidae （11.02% ）. The ballooning behaviors were observed throughout the investigation period. ANOVA analysis indicated that the number of ballooning spiders collected in early August to early September was significantly higher than that in other periods. The ballooning spiders had a body length less than 8 mm, and 91.44% of them had a length less than 3 mm. The x^2-test revealed that the individuals at immature stage were significantly higher than those at adult stage, and the male individuals were significantly higher than the females.
