摘  要：
2010～2013年位于鄂尔多斯库布齐沙地东缘周边,对鼠类组成和数量变动进行调查。结果表明:该地鼠类群落由7种鼠组成,长尾仓鼠(Cricetulus longicandatus)和子午沙鼠(Meriones meridianus)的捕获量比例较高,长尾仓鼠种群数量变动曲线与鼠类群落的较为相似,某些年份子午沙鼠种群数量变动曲线与鼠类群落较为相似。长尾仓鼠和子午沙鼠数量与群落数量有极显著正相关,且决定群落的主要特征,是群落的优势鼠种。5对鼠种的数量有极显著正相关,相关系数越高,鼠种间竞争关系越低,说明鼠种对资源利用既相对分开,也存在竞争关系。鼠类群落物种数、多样性指数和丰富度指数的年度变化较为一致,与优势度指数变化相反,这些参数与均匀性指数变化不同。

摘  要：
Composition and number variation of rodent community were investigated on the eastern edge of Kubuqi sand land in Ordos from 2010 to 2013.The results showed that rodent community was composed of seven species on the eastern edge of research area. Ratio of Cricetulus longicandatus and Meriones meridianus were higher among seven captured rodent species. Variation curve of Cricetulus longicandatus population and rodent community was similar. Variation curve of Meriones meridianus population and rodent community was similar in some years. The population of Cricetulus longicandatus and Meriones meridianus had extremely significant positive correlation with the number of rodent communities, which were dominant species and determined main characteristics of rodent community. Five pairs of rodent species had extremely significant positive correlation. The higher correlation coefficient was shown, the lower competitive relationship between rodent species would be, which indicated that there was either relatively separated or competitive resource utilization relationship among different rodent species. Annual changes of rodent communities and diversity index were similar to rodent richness index and opposite to the dominant index. The above parameters were different from the evenness index.
