对河北大学博物馆藏京津冀地区的双翅目定名标本和有关资料进行整理,共得到3亚目51科499属1378种。研究数据表明:环裂亚目的科、属、种的多样性最高,分别占相应阶元总数的58.82%、67.74%和66.55%;科级阶元中以寄蝇科的属、种数最多,分别占18.84%和17.78%;单种属260个,占总属数的5210%。研究结果还显示:京津冀地区的双翅目昆虫区系凸显古北界性质,该界特有属222个,古北-东洋界共有属277个;东北亚界属的多样性(499属,占总数的100%)远高于中印亚界(277属,占55.51%)和中亚亚界(267属,占53.51%);华北区属(499属,占100%)的多样性远高于东北区(293属,58.72%)、蒙新区(264属,52.91%)、西南区(254属,50.90%)和华中区(253属,50.70%),与青藏区(174属,34.87%)和华南区(170属,34.07%)地理渊源关系更远。 |

Based on the determined specimens which deposited in the Hebei University Museum and the related data from the literatures of the previous studies, 1378 species of 499 genera, 51 families, 3 suborders of Diptera are known from Beijing-Tianjin-Hebei of China. Data analyses show that: the diversities of Cyclorrhapha in the familial, generic and specific levels are highest, accounting for 58.82%, 67.74% and 66.55% respectively of the according grades of the total number in this area; in the familial level, the diversity of Tachinidae is the highest, whose numbers of the genera and species accounting for 18.84% and 17.78% respectively; there are 260 monotypic genera, accounting for 52.10% of the total number. Besides, the result shows that the faunal composition of the Dipetra in Beijing-Tianjin-Hebei is recognized belonging to Palaearctic, there are 222 endemic genera of the Palaearctic Realm, 277 common genera in the Palaearctic and Oriental Realms; the diversity of the genera in the Northeast subrealm (499 genera, accounting for 100% of the total number) is far higher than that in the Indo-China subrealm (277 genera, 55.51%) and the Central Asian subrealm (267 genera, 53.51%); the diversity of the genera in the North China Region (499 genera, 100%) is much more higher than that in the North-east Region (293 genera, 58.72%), Mongolo-Xinjiang Region (264 genera, 52.91%) South-west Region (254 genera, 50.90%) and Mid-China Region (253 genera, 50.70%), even more further from the Qinghai-Xizang Region (174 genera, 34.87%) and South China Region (170 genera, 34.07%) in the evolutionary relationship of biogeography. |
