Abstract: From June to October 2011,niche breadth,niche similar proportion,and niche overlap from 0.030 0-0.140 0 (L1k) and 0-0.140 0 (Lk1) were determined for Pyrola calliantha and 15 primary companion species in the Taibai Mountains between 2 253-2 928 m based on frequency,population,and coverage. Results showed that (1) niche breadth of Pyrola calliantha,Saussurea licentiana,Carex rigescens,Fragaria vesca,and Viola verecunda were high (values above 1.0);whereas niche breadth of Prunella vulgaris,Hypericum per-foratum,Acanthopanax senticosus,Anaphalis sinica,and Parasenecio forrestii were low (values of 0). (2) Only 16 species-pairs (15.2%) had a niche similar proportion above 0.50. Also,the similarity ratios for species with a high niche breadth and Pyrola calliantha were greater than that for species with a small niche breadth. (3) Niche overlap between 15 main species exhibited resource sharing in a relatively stable state. In addition,when paired with species having a small niche breadth,Pyrola calliantha,with (L1k) > (Lk1),had a lower niche overlap and had a lower (Lk1).[Ch,8 tab. 16 ref.]
