摘要: 喀喇昆仑-昆仑山昆虫区系属于典型的古北区性质,古北种占53.93%,中亚成分占16.85%,北坡受中亚成分影响大,南坡占有多数的高山成分。这一地域昆虫区系的形成和演替与其地质历史密切相关。由于印度板块不断向北挤压,喀喇昆仑-昆仑山强烈抬升,随着塔里木盆地的形成,地域性的昆虫区系便产生了,并有其特有成分的分化:亚种级的分化,种级的分化甚至属级的分化

Abstract: In this paper the authors deal with the common characteristics of the insect fauna and the component difference of the fauna under different conditions.1.During the field work in the years 1987-1988, 10322 insect specimens were collected representing 18 orders of insect and 1 order of mites. Of the collected insect orders Diptera orcupied the first place in the complexity of species and in numbers of specimen, Coleopiera the second and Lepidoptera the third.2.The species identified include Orthoptera, Neuroptera, coleoptera, Lepidoptera, Hy-menoptera and Diptera. A statistic analysis of those species shows that the fauna of Kalakorum-Kunlun Mountains belongs to the typical Palaearctic Region. The Palaearctic species number 96, occupying 53.93% of the total. The middle Asian species number 30, occupying 16.85% of the toral. Together, these two have 126 species, occupying more than 70% of the total.3.Of the species which only oocur on the northern slopes of the Kalakorum-Kunlun Mountains, the Palaearctic species number 58, occupying 52.25% of the total, the middle Asian species number 30, occupying 27.02% of the total, and the endemic species number 15, occupying 13.5% of the total.4.Of the species which occur on both the northern and the southern slopes, the Pala-carctic species number 32, occupying 50% of the total, the middle Asian species number 2, occupying 3.12% and the species occurring specially at high altitude number 12, occupying 18%.5.Of the species which only occur oil th southern slopes of the Kalakorum-Kunlun Mountains, so far as we know, there are only 2 species and they occur at high altitute only.Under the high pressure of the India landmass upon the old Eurasia continent, the Talimu region rose, the sea water retreated from there, and a round, closed basin appeared. Consequently quite a number of endemic elements, such as endemic subspecies Bombus asiaticus bai-chcngensis Wang, endemic species Eremippus yechengensis Liu, and endemic genus Conophy-mopsis Spp. came into being.
