摘　　要：对新疆哈密市马鬃山一带天然草地危害较大的毒草变异黄芪进行了全面调查研究。调查结果表明，该区域毒草变异黄芪发生总面积为８．８５万ｈｍ２，占该地区冬草场总面积的２０．４２％，平均密度５．２株／ｍ２，覆盖率达２５％～４５％，严重地段达到８０％～９０％以上。在此基础上，对变异黄芪的生物学特性、生态地理分布及对畜牧业的危害程度进行了论述，并提出了合理利用、保护草场资源。The poisonous A. variabilis in the natural grassland throughout Mazong Mountain was roundly investigated. The result showed that the poisonous plant occupied about 88.5 million hm 2 grassland which accounted for 20.42% of total grassland area. Its density was 5.2 plant/m 2 and coverage was 25%～45%, even more than 80%～90% in some heavy areas. According to the above mentioned, the biological characteristics, ecologically geographical distribution and harm to animal husbandry were discussed. The suggestion about reasonable utilization and protection of grassland resources and the comprehensive measure to control and kill this poisonous plant were given.
