摘　　要：对青藏高原蝇科昆虫进行了生物地理学研究。青藏高原已知蝇科9亚科42属574种,以特有类群占优势。其中特有属占11·9%,特有种占66·2%,文中讨论了该地区区系成分的多源性,特有成份的特异性及青藏高原北缘特有属的起源与演化,特有种的狭域分布现象及理论探讨。讨论了该地区与其它地区间隔分布的多样性及高原蝇科昆虫的适应性。分析了青藏高原的隆起与冰期对蝇科昆虫的作用。青藏高原的横空崛起以及第四纪冰期——间冰期的循环往复,导致该地区生境千差万别,使蝇科区系不仅有地域分异,且垂直差异显著。在此期间,北方物种向南入侵,南北成分交互渗透,高山类群适应进化,使许多特有成分在这里被陶冶、孕育,故而造成了该地区蝇科区系的特有性和物种的多样性。The muscid X/zang Plateau is studied biogeography of Qinghai- The known muscid species of this region are 574, which belong to 42 genera and 9 subfamilies. The endemic genera and species are preponderating, which is 11.9% of the known Chinese genera and 66.2% of the known Chinese species. The muscid polytopism and particularity of this region are discussed, especially in the origin and evolution of the endemic genera in the northern margin of Qinghai- Xizang Plateau and the narrow distribution of the endemic species. The discontinuity distribution of the species and the adaptation of the alpine muscid flies are illuminated. With the uplift of Qinghai-Xizang Plateau and the to-and-fro of the Quarternary glaciation and interglaciation, the muscid fauna was distinctly diversified in habitat and vertical zone. In the meantime, with the southward invasion of the northern species and the adaptive evolution of the alpine species, the greatest fauna particularity and species diversity are to be found in this region.
