西藏草地有毒植物分布调查

摘要

采用文献收集和实地调查结合的方法对西藏草地有毒植物的种类、生态分布进行了调查分析。结果表明,西藏草地有毒植物共计178种,分属51科,113属；其中冰川棘豆(Oxytropis Glacia-lis )、毛瓣棘豆(O.Sericopetala)、茎直黄芪(Astragaluo Strictus )、直立黄芪(A.absurgens )、狼毒(Stell-era Chamaej asme )、伏毛铁棒锤(Acontium flavum )、露蕊乌头(A.gymnanodrum)、工布乌头(A.kong-boense)、铁棒锤(A.pendulum)等有毒植物的分布较广、危害较大。并针对西藏草地主要有毒植物防治方法及利用价值进行定位,提出了牧民认知-放牧管理-毒草监测-开发利用四位一体的毒草防治利用及生态保护对策。%The main poisonous plants distributed in Tibet were surveyed.The results showed that there were 178 poisonous plant species,which belonged to 5 1 families and 1 13 genuses.In which,Oxytropis glacialis,O. Sericopetala ,Astragaluo strictus ,A.absurgens ,Stellera chamaej asme ,Acontium flavum ,A.gymnanodrum,A. kongboense and A.pendulum widely distributed and threatened.In terms of control and utilization of the poison-ous plants,the related suggestions(recognizing,grazing management,poisonous plant monitoring and utilization) were provided.
