岷江冷杉

川西亚高山红桦&岷江冷杉天然次生林的空间格局分析

Spatial Pattern Analysis in a Natural Secondary Betula-Abies Forest at Sub-Alpine Area of Western Sichuan , China

我们着重关注了小尺度范围内的空间关联特性，优势种不同径级树木与岷江冷杉幼苗、幼树空间关联性表现各异。

Particularly , we focused on spatial association at small scale . Spatial association of different size class of dominant tree species varied with seedlings and saplings .

各径级间在小尺度范围内正关联较强，随尺度增大，空间关联趋于零，在所有尺度上都未出现负关联，说明岷江冷杉种内关系协调。

Spatial association turned from strongly positive association to zero with the increasing of scale . However , there were no negative spatial associations in size-classes at all scales . It indicated that the population had a harmonious relationship internally .
