摘　　要：为探索高寒牧区鼠害草地治理的有效途径,本试验在采用C型肉毒素水剂防治草原鼠害的同时,选用本地适生草种康巴垂穗披碱草(Elymus nutans Griseb.cv.Kangba)、川草2号老芒麦(Elymus sibiricus L.cv.chuancaoNO.2)、燕麦(Avena sativa)按一定比例进行混播,通过3种不同的农艺措施(人工种草、划破草皮补播、自然封育)进行植被恢复,并连续5年定点观测治理效果。结果表明:3种不同措施对控制鼠害及草原植被恢复均有明显效果,从长期治理效果来看,划破草皮补播与自然封育措施优于人工种草措施。In order to explore an effective way to control rodent-infested grassland in alpine pasture area,while using botulinum toxin C biological agent to control rodent-infested grassland,Elymus nutans Griseb.cv.Kangba,Elymus sibiricus L.cv.chuancaoNO.2,and Avena sativa were selected as the suitable local grass species.Mixed seeding was carried out in a fixed proportion,and vegetation restoration was carried out through three different agronomic measures(full tillage and full tillage seeding,scratched turf replaying and natural enclosure),and the control effect was observed at fixed points for five consecutive years.The results showed that three different measures had obvious effects on controlling rodent damage and restoring grassland vegetation.From the long-term control effect,cut-and-replay and natural fencing measures were better than full turnover and full tillage.
