摘　　要：从放牧试验、施肥、毒杂草防除、害鼠防治4个方面研究了江河源区禾草混播人工草地的科学管理。结果表明:混播人工草地的牧草适宜利用率应为40%～60%,施肥、毒杂草防除和害鼠防治能保持混播草地群落的"暂稳态",实现混播人工草地的持续利用。In this paper, scientific management for mixed-sown grassland was studied, including grazing, fertilizing, preventing and weeding weeds, preventing and curing bandicoot （ in the Yangtze and Yellow River Headwater Region. The result showed that： feasible using rate of forage for mixed-sown grassland was 40%-60%; fertilizing, preventing and weeding weeds and toxic plant, preventing and curing bandicoot could maintain ＂temporary stabilization＂ of sown community, and then realize sustainable utilization of mixed-sown grassland in the Yangtze and Yellow River Headwater Region.
