四丰山风景区鳞翅目昆虫多样性调查

A Survey of Lepidoptera Insect Diversity in Sifeng Mountain Scenic Area

【目的】为掌握四丰山风景区鳞翅目昆虫的分布情况,了解其分布规律,探究四丰山风景区鳞翅目多样性。【方法】自2021年4月至2021年9月,选取该风景区内林缘、草甸、湿地、灌丛等4种生境采样点,采用直接网捕法。【结果】采集鳞翅目昆虫1015头,经鉴定统计,共计54种,隶属于13科39属;对以上种类进行分析发现,4种生境样本个体数、物种数由多到少依次为林缘、灌丛、草甸、湿地,Shannon-Wiener多样性指数、Simpson优势度指数、丰富度指数都是在7月林缘达到了最大值,于9月林缘达到最小值。Pielou均匀度指数于4月湿地生境达到最大值,9月林缘生境达到最小。【意义】调查结果可为四丰山鳞翅目昆虫资源提供数据基础。

[Objective]This study was conducted to grasp the distribution of Lepidopteran insects,understand their distribution rules,and explore their diversity in Sifeng Mountain Scenic Area.[Method]From April,2021 to September,2021,4 habitat sampling points were selected in the scenic area,including the forest edge,meadow,wetland and shrub,and the direct net capture method was used.[Result]1015 Lepidoptera insects were collected.After identification and statistics,a total of 54 species belonged to 13 families and 39 species.The number of individuals and species in the four habitat samples was in the following descending order:forest margin>shrub>meadow>wetland.Besides,Shannon-Wiener diversity index,Simpson dominance index and richness index all reached the maximum value in July,while the minimum value reached in September.Pielou evenness index reached the maximum value in April in the wetland habitat,with the minimum in forest edge habitat in September.[Significance]This survey provided data basis for Lepidoptera resources in Sifeng Mountain.
