摘　　要：采用联结系数和共同出现百分率,对东祁连山高寒地区柳灌丛群落种间关联性进行了研究。结果表明,柳灌丛群落内灌木植物种群间的关系表现为以下3种类型1)正联结。海拔3050m除坡柳与杯腺柳之间无关联外,其它种对均表现为正联结,海拔3050、3100、3200以及3250m处金露梅与高山绣线菊之间、海拔3150~3350m山生柳与金露梅之间、海拔3300、3350以及3450m处山生柳与头花杜鹃之间等,表现出正关联;2)负联结。海拔3100m处金露梅和川滇柳之间、海拔3150m处山生柳与坡柳以及金露梅和坡柳之间、海拔3450m处山生柳与杯腺柳之间、川滇柳和头花杜鹃之间,表现为负关联;3)无联结。海拔3050m坡柳与杯腺柳之间、海拔3100~3250m头花杜鹃与其它种群之间以及海拔3400m处除高山绣线菊与头花杜鹃之间外,各种群之间,无任何关联种对。The study by using associate coefficient and simultaneous emergence percentage showed that on the alpine grassland of east Qilian Mountains,the interspecific relationships in Salix shrub community could be classified into three kinds,i.e.,1) positive association,which was shown from the relationships between the couples of all plant species except those between S. myrtillacea and S. cupularis,and Dasiphora fruticosa and Spiraea alpina at the altitudes of 3 050,3 100,3 200 and 3 250 m,and S. ortrepha and Rho...
