摘要
东祁连山大阴坡几种杜鹃种群在不同海拔高度上的垂直分布对策是各物种生态位重叠与分离的结果:千里香杜鹃和头花杜鹃为海拔3300m以下梯度内的优势种;陇蜀杜鹃在海拔3300m以上更湿冷的范围内开始增加,并占绝对优势;烈香杜鹃在3400m时分盖度最大,在低处与千里香杜鹃和头花杜鹃伴生,在高处与陇蜀杜鹃伴生。
Overlapping and separation of niche can explain the vertical distribution strategy of four Rhododendron species on elevation on northern slope of eastern Qilian Mountain. Below alt.3300m of the northern slope, it is occupied mainly by R. thymifoliumand R. capitatum. R. przewalskii become the dominant species up 3 300 m, the cover of R. anthopogonoides get maximum at alt. 3400m, associated with R. thymifolium and R. capitatum downward, company with R. przewalskii upward.
