摘要
本文从种数、特有物种和区系构成等角度分析了青藏高原丽蝇科昆虫的物种多样性。青藏高原已知丽蝇5亚科35属120种,占中国已知种数的44.28%,其中特有种55种,占该地区总种数的45.83%;区系构成以特有种、古北界+东洋界共同种及典型的东洋界种和古北界种为主,但澳洲界、新北界、非洲界和新热带界共同种也占一定比例。文中讨论了该地区特有种丰富的原因及地质历史环境对其的影响,分析了区系构成中各种区系成分的比例及形成原因。
The diversity of the family Calliphoridae （ Diptera： Calliphoridae） is studied, including the species total number, endemic species and fauna in the Qinghai-Tibetan Plateau. A total of 120 species, occupying 44. 28% of the known Chinese species of the family are known in this region. They belong to 5 subfamily and 35 genera, of which 55 species, occupying 45.83%, are endemic to this region. The endemics, the Palaearctic ＋ Orientals, the Orientals and the Palaearctics are dominant in the fauna. There are also some species distributed in other zoogeographic realm. The possible reasons for the richness of the endemic species and the influence by the geological and ecological factors are discussed. The proportions of the components in the fauna are listed and their possible reasons are also discussed.
