摘　　要：本文对高原鼢鼠和高原鼠兔骨骼中的无机常量元素Ｋ、Ｎａ、Ｃａ、Ｍｇ、Ｐ和Ａｌ进行了比较分析。研究结果表明，高原鼢鼠骨骼中Ｃａ、Ｐ、Ａｌ的含量极显著地高于高原鼠兔（Ｐ＜０．０１），Ｋ含量高原鼢鼠极显著地低于高原鼠兔（Ｐ＜０．００１），Ｎａ和Ｍｇ的含量两者间无显著差异（Ｐ＞０．０５）；骨骼各部位元素总量的分布顺序为：高原鼢鼠下肢骨＞头骨＞脊柱；高原鼠兔头骨＞下肢骨＞脊柱。１５个元素对中，大部分元素之间线性相关非常显著，其中高原鼢鼠１０对呈显著的线性相关。The contents and distributions of the inorganic macroelements K,Na,Ca,Mg,P and Al in skeletons of plateau zoker( Myospalax baileyi ) and plateau pika ( Ochotona curzoiae ) were studied in the area of Haibei Research Station of Alpine Meadow Ecosystem.The results are as follows: The contents of Ca,P and Al in skeleton of plateau zoker are very significantly higher than that in skeleton of plateau pika (P <0 01),the contents of K in skeleton of plateau zoker are extremely significantly lower than that in skeleton of plateau pika (P <0 001),and the contents of Na and Mg between plateau zoker and plateau pika are not different (P >0 05). The distributions of total amount of macroelements in different parts of skeleton are:plateau zoker leg bone>head bone>backbone,plateau pika head bone>leg bone>backbone. In total 15 element pairs,10 pairs for plateau zoker and 13 pairs for plateau pika are significantly correlated.
