Location QTPH。方法编制青海省326种地方性蚜虫分布数据库。研究区域被划分为2度x 2度操作地理单元的网格。采用地方性简约分析（PAE）确定特有区，利用地理信息系统（GIS）绘制特有物种多样性格局。结果鉴定出蚜虫科14亚科138属326种特有种。主要结论本研究确定了主要的蚜虫流行中心。此外，在物种丰富度和特有度模式之间存在显著的一致性。其特有模式极有可能受近期青藏高原抬升的影响。
Aim The study aimed to identify areas of endemism for aphids in the Qinghai-Tibetan Plateau and the Himalayas (QTPH), and to test congruence between patterns of endemism and patterns of overall species richness identified in a previous study.Location The QTPH.Methods A distribution data base of 326 endemic aphids in the QTPH was compiled. The study area was divided into a grid of 2 degrees x 2 degrees operative geographical units. Parsimony analysis of endemicity (PAE) was used to identify areas of endemism, and the diversity patterns of endemic species were then mapped using GIS.Results We identified 326 endemic species belonging to 138 genera within Adelgidae and 14 subfamilies of Aphididae. Five areas of endemism were found using PAE analysis: the eastern Himalayas, the western Himalayas, north-western Yunnan, southern Tibet and the eastern QTPH. Maps of patterns of endemism identified four major centres for endemic aphids, namely the western Himalayas, the eastern Himalayas (or Sikkim-Assam Himalayas), north-western Hengduan Mountains and the mountains of southern Gansu Province, and three minor centres, southern Tibet, south-eastern Tibet and the eastern Qinghai Province in the north-eastern QTPH.Main conclusions Our study identifies major centres of aphid endemism. Furthermore, there is a noticeable congruence between patterns of endemism and patterns of species richness. The patterns of endemism were most likely influenced by the recent uplift of the QTPH.
