摘　　要：综述长白山区牛皮杜鹃分布、生境、遗传多样性、形态、繁殖等研究现状.结果显示:牛皮杜鹃为杜鹃花科常绿杜鹃亚属常序杜鹃亚组,国内分布以长白山高山苔原带为主,吉林省二级保护植物,濒危种;气候变暖及雪斑线上升引起牛皮杜鹃种群沿海拔上移、扩张,群落内物种间竞争显著;土壤动物对牛皮杜鹃及群落植物凋落物分解作用明显;遗传多样性丰富,不同地带牛皮杜鹃遗传差异较大;有性、无性繁殖均可获取种源.建议加强牛皮杜鹃繁殖研究;开展以小叶章为代表的草本植物种群快速扩张引起的牛皮杜鹃种群衰退研究;建立长期样地,监测牛皮杜鹃种群变化.The research status of distribution,habitat,genetic diversity,morphology and reproduction of Rhodo-dendron aureum in Changbai Mountain area was reviewed.Rhododendron aureum belongs to the Ericaceae,Rhododendron Subsect,Pontica Sleumer is mainly distributed in the alpine tundra belt of Changbai Mountain.It is a second-level protected,endangered plant in Jilin Province.The climate warming and snow line rising caused the migration and expansion of Rhododendron aureum Georgi population along the altitude,and the competition among species within the community was significant.Soil fauna exhibited an obvious effect on the litter decomposition of Rhododendrons aureum Georgi and community plants.Rhododendron aureum showed ample genetic diversity with great genetic difference in different zones.Provenances can be obtained by sexual and asexual reproduction.It is suggested to strengthen the research on Rhododendron aureum reproduction.It is also recommended to study on decline of Rhododendron aureum population caused by the rapid expansion of herbaceous species,represented by Deyeuxia angustifolia.The long-term monitoring plot is established to monitor the population changes of Rhododendron aureum.
