扎龙湿地季节性湿草甸土壤昆虫群落多样性

Soil Insect Community Diversity of Seasonal Wet Meadow in Zhalong Wetland

为更好地开展国际重要湿地——扎龙湿地的保护工作,以扎龙湿地季节性湿草甸为试验对象,系统调查了扎龙湿地湿草甸土壤昆虫群落,共采集到土壤昆虫12目47科67种,种类和数量以双翅目、弹尾目和鞘翅目居多;土壤昆虫群落季节分布差异显著,以7月份为活跃高峰期;多样性指数、均匀度指数和丰富度指数季节动态均相一致;种—多度关系符合对数正态分布模型。

An investigation was conducted to protect Zhalong wetland of international importance,with the observation data of Zhalong wetland ecological system and investigate systematically soil insect community in seasonal wet meadow in Zhalong wetland.We collected the soil insects of 12 orders,47 families,67 species.The major species and quantity were Diptera,Collembola and Coleoptera.The seasonal distribution of soil insect community is significantly different,and July was the active peak season.The seasonal dynamics of the diversity index,evenness index and richness index are consistent.The species-abundance relationship conforms to logarithm normal distribution model.
