摘　　要：为了解甘肃省民勤连古城国家级自然保护区鼠类群落结构和多样性,根据不同生态类型,分别在石羊河林业总场、勤锋保护站小茨墩管护点、苏武山管护区和南湖自然保护站设置4个样地,每个样地随机设置5条样线,共计20条,通过铗日法对其种类及数量进行了统计和分析,探究鼠类群落结构与多样性。结果表明:调查区鼠类优势种为大沙鼠、子午沙鼠与三趾跳鼠,南湖自然保护鼠类丰富度指数和多样性指数较高;聚类分析与主成分分析结果表明,连古城保护区主要存在两个鼠类群落,一种以大沙鼠、三趾跳鼠与子午沙鼠为优势种的群落,另一种以小家鼠与褐家鼠为次优势鼠种。由此可见,甘肃省民勤连古城国家级自然保护区鼠类群落结构复杂,多样性较高。In order to understand the community structure and diversity of rodents in Liangucheng National Nature Reserve of Minqin,Gansu Province,total 4 sample plots were set up according to different ecological types,including Shiyang River Forestry Farm,Xiaozidun Management Protection Site of Qinfeng Protection Station,Suwushan Management Protection Station and Nanhu Nature Protection Station.5 line transects were randomly set in each sample plot,a total of 20 were analyzed.The species and quantity of rodents were counted and analyzed by the method of trap day method,and the community structure and diversity of rodents were investigated.In the survey area,the dominant species of rodent community were Rhombomys opimus,Meriones meridianus and Dipus sagitta.Typically,Nanhu Nature Reserve had higher richness and diversity index than other three habitats.The results of cluster analysis and principal component analysis(PCA)indicated that there were mainly two rodent communities in the Liangucheng National Nature Reserve,one community was dominated by the R.opimus,the D.sagitta and the M.meridianus,the other community was dominated by the M.musculus and R.norvegicus.Therefore,it can be seen that the rodent community structure is complex and the diversity is relative high in Liangucheng National Nature Reserve of Minqin,Gansu Province.
