The phylogenetic relationships of the avian genus Crossoptilon were studied by comparing mitochondrial control region(D-loop)and cyt b gene nucleotide sequences,with the Lophophorus impejanus and Lophura swinhoii as the outgroups.Using the synthesizing characters of morphology,ecology and biogeography to combine with Maximum parsimony(MP),Maximum Likelihood(ML)and Bayesin trees,we found that:① C.crossoptilon and C.harmani were closely related and C.harmani was relatively primitive;② C.auritum and C.mantchuricum had a close relationship and C.auritum was relatively primitive;③ the genus Crossoptilon could originate in the boundary region of Sichuan,Yunnan and Tibet.One branch remained near the center of origin and diverged into C.crossoptilon and C.harmani;the other branch spread towards north China and diverged into C.auritum and C.mantchuricum.
物种保护是生物多样性保护的核心问题。野生动物资源是地球生物多样性的重要组成部分,不仅在维护整个生态系统的稳定及其生态服务方面具有重要功能,更是生态系统健康发展的标志（Hoffmann et al.,2010;Scheffers et al.,2012;魏辅文等,2014）。然而,由于全球人口爆炸性增长、环境变化和过度利用,
