摘　　要：青岛百合(Lilium tsingtauense Gilg)是中国百合科植物的特有种,这一物种作为小种群的代表具有一定的普遍意义。根据已有文献资料和野外调查结果,分析了青岛百合的生境特点和分布现状。结果显示,目前青岛百合的集中分布地位于崂山北九水以南海拔400～1000m的区域内,一般生长于阴坡或半阴坡的森林中,具有充足的水分和光照等条件。在这一区域可见到成片呈斑块状分布的种群,斑块之间的距离依地形、地貌及人类活动的强度不同而远近不一。斑块大小各异,以离散斑块形式存在,生境斑块间的连通性较好,推测这一种群是较为典型的植物复合种群的代表。Lilium tsingtauense was an endemic, rare and endangered plant in China. It was of universalism for representative of a small population. Based on existing data and all-round investigation, the habitat and distribution characteristics of L. tsingtauense was studied. The spieces can only be found at altitude 400 ～1 000 m in the beauty spot of Beijiushui of Mountain Lao, and lives in patchy habitats. The habitat was located at the shade slope or semi-shade slope where the forest coverage developed well and the sunlight and soil humidity could meet the needs of the species. Because of landform and the disturbance of human, the size and distance of each habitat was different. The population of L. tsingtauense might be the representative of typical metapopulation.
