Abstract： Based on the concept and practice of grassand livestock equivalent and “Standard sheep unit”，this paperdefines the“Standard rodent unit”and explores its practical significance in grassland rodent survey，monitor ingand pestcontrol management.Referring to“Standard sheepunit"conceptionand the research progressof grassland rodents prevention and control in recent years，we analyzed the measurement indicators for relevant rodent standard unit and the methodologies for calculating rodents food equivalents.The definition of“Standard rodent unit"was as follows，based on the common weight ofthe average grassand rodents，one unit represents the daily loss caused by a 100g rodent species consuming，cuting and storing 50g fresh grass（about 50% of its body weight），which converts to 10g of dry grass （assuming a moisture content of 20% ）. Eighty rodent units are equivalent to one standard sheepunit，with conversion ofdiferent rodents basedon their weight differences.A pre liminarily measurementrelationship among“rodent-grass-livestock”at the level offorage intake was established， which willprovide standard and basis for quantifying the foraging and food equivalents ofdiffrent herbivores.

Key words： Standard rodent unit; Grassand rodents; Rodents prevention and control; Prevention and control threshold

草地鼠害是指在草地生态系统中由于鼠类数量剧增、活动加剧，对草地植被、土壤、环境及生态系统造成一定危害，超过了益害转化防控阈值，对区域草地健康和保护利用构成损害的一类草地退化现象[1]。（剩余12246字）
