四川卧龙亚高山林线生态交错带群落的种多度关系

By using species abundance distribution models Broken Stick,Geometric Serices,Log Series and Truncated Log Normal,percent cover of every species was used as indicator of abundance to study species abundance relations of herb communities along transects across subalpine timberline ecotone of Abies faxoniana forest in Balang Mountain of Wolong Natural Reserve,Sichuan Province,southwestern China.The results showed that Truncated Log Normal and Log Series distribution models can well fit to the species a...
