1) niche similarity
生态位相似性比例
1.

基于对秦岭山区濒危植物秦岭冷杉(Abies chensiensis)分布群落的样地调查,采用定量分析的方法,研究了秦岭冷杉群落中主要种群的生态位宽度、生态位相似性比例和生态位重叠,结果表明:(1)分别用Levins和Shannon-weiner两指数测得的主要种群的生态位宽度结果基本一致,即乔木、灌木和草本层中生态位宽度最大的依次为秦岭冷杉、箭竹(Sinarundinaria nitida)和苔草(Carexlanceolata),秦岭冷杉与生态位宽度值大的种群易形成混交林;(2)生态位宽度较高的两个种群,种对相似性比例一般较高;(3)秦岭冷杉群落中各主要种群之间的生态位重叠程度较低,表明种群对群落环境资源的分享比较充分,群落处于相对稳定状态。
