摘要
2009年6—11月,在吕梁山中部农林生态区进行了啮齿动物调查及分析,根据当地的地理特征和鼠类的栖息生境特征,把该区划分为3种不同生境。采用铗日法进行鼠类密度调查,共置放鼠铗8 117个,捕获啮齿动物714只,属4科8种,其中优势种为达乌尔鼠兔、社鼠、长尾仓鼠、子午沙鼠。对3种不同生境中鼠类种群多样性指数、均匀度指数、优势度指数分析发现,生境差异、植被覆盖度和人为干扰对鼠类群落多样性均有一定影响。
Investigation of the rodent and the rodent community in central Lvliang Mountains from June to November 2009 was conducted.According to local geographic features and characteristics of rodent habitats,the area was divided into three habitats.A total of 714 belonging to 4 families 8 species were captured with 8 117 trap-days.The dominant species were O daurica,R niviventer,C longicaudatus and M meridianus.The diversity index,evenness index and dominance index were analyzed.Results showed that the diversity of rodent community was affects by habitats,vegetation coverage and human disturbance.
