【摘要】 为了了解鄂尔多斯沙地鼠类群落组成年度变化趋势,2008年到2012年采用夹日法对鄂尔多斯沙地鼠类群落组成及其数量进行了调查。调查结果显示,鄂尔多斯沙地鼠类群落由七种鼠组成,鼠类群落在5年间不断地发生演替。长爪沙鼠、子午沙鼠的年度变化趋势均与鼠类群落的年度变化趋势一致。多样性指数和丰富度指数的年度变化较为一致,物种多样性与丰富度和均匀度都有极显著的正相关关系。更多还原

【Abstract】 To understand the annual change trend of composition of rodent community in Erdos sandland,composition and number dynamics of rodent community were investigated by the day trapping method in Erdos sandland from 2008to 2012.The results showed that rodent community was composed of seven species in Erdos sandland.The succession of rodent community constantly occured in 5years.Annual change trend of Meriones unguiculatus and Meriones meridianus both were the same as that of rodent community.Annual change of diversity index was the same as that of richness index.The species diversity showed significantly positive correlation with the richness and the evenness.更多还原
