By comparing the change of internal organs of plateau zokor ( Myospalax baileyi) along the altitude gradient, the adaptability of plateau zokor to the environment was assessed on the basis of the morphology and structure. The result showed that the wet heart weight and dry heart weight, dry weight of spleen and lung, wet stomach weight and dry stomach weight, and wet cecum weight of male plateau zokor were significantly positive correlated with the altitude, however, the wet kidney weight, and length of large intestine were significantly negative correlated with the altitude. The fresh heart weight and dry heart weight, fresh weight and dry weight of the lungs, wet stomach weight, fresh cecum weight and cecum length of female plateau zokor were significantly positive correlated with the altitude, and the fresh weight and dry weight of liver, dry spleen weight, dry weight and fresh weight of kidney, and dry large intestine weight, and length of large intestine were significantly negative correlated with the altitude. Therefore, the correlation between the organ and elevation of plateau zokor indicated that this species adopted compensatory adaption against the different living environment, energy demand, oxygen content, and pathogens. 2015,34(4): 574-578 收稿日期：2014-12-22 DOI：10.11984/j.issn.1000-7083.2015.04.016 分类号：Q955;Q959.8 基金项目：国家自然科学基金项目(31370405, 31372197); 青海省科技支撑计划项目(2014-NS-113) 作者简介：张守栋(1989—),男,硕士研究生,研究方向:进化生态学,E-mail:zhangshoudong666@163.com *通讯作者：苏建平,E-mail:jpsu@nwipb.cas.cn;林恭华,lingonghua@163.com 参考文献： 刘璐, 徐金会, 孔杰, 等. 2010. 三种鼠类消化道长度和重量的比较[J]. 曲阜师范大学学报: 自然科学版, 36(2): 109-112. 刘国富, 温得启, 胡晓梅. 1985. 高原鼠兔和高原鼢鼠乳酸脱氢酶同工酶的初步研究[J]. 兽类学报, 5(3): 223-228. 王德华, 王祖望. 2000. 高寒地区高原鼢鼠消化道形态的季节变化[J]. 兽类学报, 20(4): 270-276. 王晓君, 魏登邦, 魏莲, 等. 2008. 高原鼢鼠和高原鼠兔肺细叶的结构特征[J]. 动物学报, 54(3): 531-539. 杨传华, 都玉蓉, 谢久祥, 等. 2012. 两种鼢鼠内脏器官形态差异及其分类学意义[J]. 兽类学报, 32(3): 1-10.
