摘　　要：The origins and phylngenetic patterns were assessed for G. przewalskii and G. eckloni by analyzing the complete mtDNA cytochrome b gene sequence （1140bp）, Phylogenetic analyses further supported that there were three mtDNA lineages （A-C） identified in G, przewalskii and G, eckloni, demonstrating that outer takers of the first gill have little significance in the phylogeny of the Gymnocypris fishes. The network established showed that G, eckloni of the Yellow River specific haplotype A1 was a founder and it radiated all haplotypes of G, przewalskii which suggested G, przewalskii might only originate from one of two maternals of G, eckloni from the Yellow River, Fs test and mismatch analysis showed at least two expansion events in the population of G, przewalskii about 0. 2734 Ma and 0.0658 Ma, while G, eckloni from Qaidam Basin could have experienced severe bottleneck effect about 0. 0693 Ma, The population expansion was detected in subclades A1 and A21 with the most recent common ancestor （TMRCA） about 0. 2308 ± 0.01 Ma and 0.1319 ± 0.015 Ma, respectively, which were within the geological age range of ＂Gonghe Movement＂ event that caused the separation of Lake Qinghai from the upper Yellow River, These results suggested the effect of the fish diversification by rapid uplift of the Qinghai-Tibetan Plateau in the Late Pleistocene.起源和种系发生的模式为 G 被估计。przexvalskii 和 G。由分析完全的 mtDNA 细胞色素 b 基因顺序(1140bp ) 的 eckloni。种系发生的分析进一步支持了那有三个 mtDNA 系(交流) ，在 G 识别。przewalskii 和 G。eckloni，证明第一鳃的外部 rakers 在 Gymnocypris 的发展史有很少意义钓鱼。建立的网络显示出那 G。黄河特定的 haplotype 艾尔的 eckloni 是一个创始人，它散发了 G 的所有 haplotypes。建议了 G 的 przexvalskii。przexvalskii 可能仅仅从 G 的二 maternals 之一发源。从黄河的 eckloni。F 测试和失配分析在 G 的人口显示出至少二个扩大事件。przexvalskii 大约 0.2734 妈并且 0。0658 妈，当时 G。ecklonifrom Qaidam 盆能经历了严重瓶颈效果大约 0.0693 妈。人口扩大与最近的普通祖先(TMRCA ) 在 subclades 艾尔和 A21 被检测大约 0.2308 ± 0 .01 妈和 0.1319 ± 0 .015 妈，分别地它在从上面的黄河引起了金海湖的分离的 Gonghe 运动事件的地质的年龄范围以内。这些结果建议了鱼多样化的效果由快速在迟了的更新世 Qing-hai-Tibetan 高原高举。
