摘要
目的从种数和区系成分等角度分析四川省峨眉山地区有瓣蝇类的物种多样性。方法采用区系分析及生物多样性分析法;多样性分析采用Shannon-Wiener指数,优势度指数采用BergerPaeker指数。结果整理统计四川省峨眉山地区有瓣蝇类7科81属224种;其中蝇科和花蝇科无论在属级水平还是种级水平,均占有较大优势,分别占该地区已知属数和种数的24.69%、22.22%和30.80%、31.25%。特有种62种,占该地区分布种数的27.68%;东洋界种59种,古北+东洋界种67种,分别占该地区分布种数的26.34%和29.91%;多样性指数在属级水平和种级水平分别为1.72和1.64。结论四川省峨眉山地区有瓣蝇类物种多样性较高,其区系特征是以特有成分、东洋界区系成分、古北+东洋界成分为主,其他成分共存的特征。
Objective To analyze the species diversity and faunal composition of Calyptratae in Emeishan area of Sichuan province. Methods Faunal analysis and biodiversity analysis were employed, using Shannon-Wiener index and Berger Paeker index as indicators for diversity and dominance. Results In the study area 224 species, 81 genera and 7 families of Calyptratae were recorded. Muscidae and Anthomyiidae were predominant at the genera and species levels, accounting for 24.69% and 22.22% of all known Calyptratae genera respectively, and 30.80% and 31.25% of the species in the region, respectively. Sixty-two endemic species accounted for 27.68% of the total. Fifty-nine Oriental realm species and 67 Palaeoarctic and Oriental realm species, accounted for 26.34% and 29.91%, respectively. The diversity indexes at the genera and species levels were 1.72 and 1.64, respectively. Conclusion The Emeishan area of Sichuan province has high Calyptratae species diversity and was characterized by endemic elements, Oriental realm elements, Palaeoarctic and Oriental realm elements and other coexisting elements.
