【Abstract】 The structure of ungulate communities were investigated at Yanchiwan of Subei County in 1987. Results are as follows:1. The comparative complexity due to natural environment of this place causes species of ungulate to have comparatively numerous. A total of three families and seven species are found there. Among them, five species belong to rare animals.2. According to species composition and dominance of the ungulate and combin-ing with ecological condition, they can be divided into four communities;Ⅰ . pseudois nayaur + Ovis ammon + Cervus albirostris community. Ⅱ . Cervus albirostris + Ovis ammon + poephagus mutus community. Ⅲ. Procapra picticaudata + Asinus kiang community.Ⅳ. Asinus kiang + Gazella subgutturosa community.3. The line transect sampling method was used, density of ungulate were calc-ulated in four different ecological habitats (Table 1).4. Among the four communities, the index of diversity on the community Ⅱ is higher (0.9179) and that of community Ⅲ is lower (0.3800). The index of evenness on the community　Ⅳ is higher (0.9887) and that of community Ⅲ is lower (0.3459) (Table 2, 3).5. Cervus albirostris, poephagus mutus and Asinus Kiang are the conserved spe-cies of the first category in China, the endangered species in the Red Data Book and CITES. Their numerical distributions were delineated in Fig. 1 .更多还原
