摘要
为研究直翅目昆虫资源群落特征,了解陕西商州丹江源国家湿地公园建设对直翅目昆虫的影响,于2021和2022年的5-10月,在该湿地公园内选取林地生境、河流生境和城市生境等3种生境类型进行直翅目昆虫资源调查。调查结果表明,该地区直翅目昆虫种类共计30种,隶属于8科25属。其中,斑翅蝗科昆虫种类最多为9属11种,占记录直翅目昆虫种类的36.70%。三种生境中,昆虫群落Shannon-Wiener多样性指数在林地生境中最高(2.87),在城市生境最低(2.44)。城市生境中,昆虫群落Pielou均一化指数最高(0.95)。直翅目昆虫群落相似性在林地生境和河流生境间最高(0.70),结果表明河流生境为林地生境和城市生境形成连接与过渡。
To study the community characteristics of Orthoptera insect resources and understand the impact of the construction of Shangzhou Danjiangyuan National Wetland Park in Shaanxi Province on Orthoptera insects,an investigation into Orthoptera insect resources was conducted in three habitat types-woodland,river,and urban habitats-within the wetland park from May to October 2021 and again from May to October 2022.The survey results revealed a total of 30 species of Orthoptera insects belonging to 25 genera across 8 families in this area.Among them,the Acrididae family had the most diverse representation with 11 species across 9 genera,accounting for 36.70%of the recorded Orthoptera species.Among the three habitats,the Shannon-Wiener diversity index of insect communities was highest in the woodland habitat(2.87)and lowest in the urban habitat(2.44).Conversely,the Pielou evenness index was highest(0.95)in the urban habitat.The similarity of Orthoptera insect communities was highest between the woodland and river habitats(0.70),indicating that the river habitat serves as a bridge and transition zone between the woodland and urban habitat.
