四川九寨沟国家级自然保护区蛾类多样性调查

Investigation on Moth Diversity in Jiuzhaigou National Nature Reserve, Sichuan Province

  • 摘要: 在四川九寨沟国家级自然保护区内,选取落叶阔叶林、针阔落叶混交林、高山针叶林和草甸3种植被类型生境,于2020年7—10月利用灯诱法进行定期采集蛾类,比较不同生境样地内蛾类群落结构与多样性差异。3种生境样地内共获得蛾类成虫1430头,分属16科151属227种,其中夜蛾科物种数最多,尺蛾科个体数最多。多样性结果表明落叶阔叶林和针阔落叶混交林生境内的蛾类群落Margalef丰富度指数和Shannon多样性指数均高于高山针叶林和草甸,群落表现稳定。其中Margalef丰富度指数在科级指数变化与属、种级指数变化表现明显差异,而其它指数变化呈一致性。群落相似性分析结果表明,落叶阔叶林与针阔落叶混交林之间相似性最高(0.4178),高山针叶林和草甸样地内蛾类群落与其他2种生境内的蛾类群落的相似性较低(<0.1)。

     

    Abstract: The composition and diversity of moth in spatial differences were compared through collecting the specimen of moth (Lepidoptera) using light trap from July to October 2020 in three habitats, including deciduous broad-leaved forest, coniferous and broad-leaved mixed forest, and alpine coniferous forest and meadow, in Jiuzhaigou National Nature Reserve in Sichuan Province. A total of 1430 adult moths belonging to 16 families, 151 genera, and 227 species were collected, among which Noctuidae had the highest number of species and Geometridae had the highest number of individuals. The diversity results showed that the Margalef richness index and Shannon diversity index of moth in deciduous broad-leaved forest, coniferous and broad-leaved mixed forest plots were higher than those in alpine coniferous forest and meadow plot, and the community performance was stable. Among them, the Margalef richness index showed obvious differences in the diversity characteristics of family, genus, and species, while the changes of other indexes were consistent. The results of community similarity analysis showed that the similarity of moths collected from deciduous broad-leaved forest and coniferous and broad-leaved mixed forest was the highest (0.4178), moth community in the alpine coniferous forest and meadow had a low similarity with those in the other two habitats (P<0.1).
