【摘要】 2023年6—12月采取线路调查+标准地调查法对宁夏草原啮齿动物的发生和危害情况开展调查。按宁夏草原类型的差异性和不同区县的面积大小，在11个县（区）设立了300个调查点，调查了36条线路的259个样点，其中167个调查点没有发现鼠洞，92个调查点的鼠洞洞口密度为5～730个·hm^-2，平均为128个·hm^-2。由于地表植被茂盛，土丘不明显，没有计数宁夏南部4县（区）山地草甸的鼹形鼠科动物土丘数。44个标准样地中，地上鼠标准样地33个，其中7个样地捕获数为0，其余26个样地夹捕率在0.5%～4%之间。捕获子午沙鼠、阿拉善黄鼠、五趾跳鼠、三趾跳鼠、灰仓鼠5个鼠种71只个体，整体夹捕率为1.2%。设立地下鼠标准样地11个，其中2个样地捕获数为0，其余8个样地地箭捕获率在3.33%～20%之间，捕获麝鼹和甘肃鼢鼠等2个种23只个体，总体地箭捕获率为7%。本次调查获得了宁夏草原有害啮齿动物发生种类、分布及为害程度，系统评估宁夏草原啮齿动物发生为害现状及未来趋势，为宁夏草原啮齿动物管理提供基础数据和科学管理建议。更多还原

【Abstract】 From June to December 2023, a survey was conducted on the occurrence and harm of rodents in the grasslands of Ningxia using the method of line inspection and standard site investigation. According to the differences in grassland types and the area of different counties in Ningxia, 300 inspection points were set up in 11 counties, and 259 sampling points of 36 routes were inspected. Among them, 167 inspection points did not find mouse holes, and the density of mouse hole openings in 92 inspection points was 5-730 per hectare, with an average of 128 per hectare. Due to the lush vegetation on the surface and indistinct soil mounds, the number of moles in the mountain meadows of the four counties in southern Ningxia was not counted. Among the 44 standard plots, there were 33 above ground mouse standard plots, of which 7 plots had a capture rate of 0, and the remaining 26 plots had a capture rate between 0.5% and 4% and 71 individuals from 5 species of rodents were trapped, including the Meriones meridianus Pallas, Spermophilus alaschanicus, Allactaga sibirica Forster, Dipus sagitta, and Cricetulus migratorius, with an overall trapping rate of 1.2%. 11 underground mouse sample plots were established, with 2 plots having a capture rate of 0 and the remaining 8 plots having a capture rate of 3.33%-20% and 23 individuals from 2 species were trapped, including the Parascaptor leucurus and Eospalax cansus, with an overall capture rate of 7%. This survey obtained the types, distribution, and degree of harm of harmful rodents in the Ningxia grassland, systematically evaluated the current situation and future trends of rodent harm in the Ningxia grassland, and provided basic data and scientific management suggestions for rodent management in the Ningxia grassland.更多还原
