摘　　要：鼢鼠严重威胁青海省农业生产、农牧民财产安全和生态环境安全。通过2013—2020年青海省农区鼢鼠发生面积和鼠密度变化动态的调查统计,明确青海省农区鼢鼠发生面积和数量总体呈减少态势,东部农业区、海南台地农业区、青南高原小块农业区平均发生面积占比分别为70.48%、27.16%、2.36%,平均密度分别为7.31、12.57、6.64只/hm^(2),在发生面积最大的东部农业区中,脑山、浅山、川水3种类型区域平均发生面积占比分别为70.47%、29.35%、0.18%,平均密度分别为15.32、6.58、0.02只/hm^(2)。摸清各区域农区鼢鼠发生规律,可为探寻科学有效的防控对策、促进鼠害绿色防控提供重要参考。The zokor poses a significant threat to agricultural pr oduction,property security of farmers and herdsmen,and ecological environment security in Qinghai Province.Based on the survey statistics of the zokor's occurrence area and its population dynamics from 2013 to 2020,it is evident that the occurrence area and the population of zokors in agricultural areas of Qinghai Province are generally decreasing.In the eastern agricultural area,the Hainan tableland agricultural area,and the Qingnan plateau small block agricultural area,the average annual occurrence area of zokors accounted for 70.48%,27.16%,2.36%,respectively,and the average zokor density was 7.31,12.57,6.64 individuals per hectare,respectively.In the eastern agricultural area with the largest area of zokor's occurrence,the average occurrence area of high hill regions,middle mountain areas,and irrigated agricultural areas accounted for 70.47%,29.35%,and 0.18%,respectively,and the average zokor density was 15.32,6.58,0.02 individuals per hectare,respectively.Determing the occurrence pattern of zokor in agricultural areas in each region can provide a valuable reference for developing scientific and effective prevention and control measures,as well as promoting environmentally friendly prevention and control of rodent.
