根据生态种组原理 ,应用 Fuzzy聚类方法从 4种不同立地类型组的杉木天然混交林中 61种杉木潜在伴生树种中选择杉木适宜伴生树种 ,结果如下 ,中山阳坡组适宜伴生种有 7种 ;中山阴坡组适宜伴生种有 8种 ;低山阳坡组有 8种 ;低山阴坡组有 1 3种 ;不同立地类型组中 ,杉木适宜伴生种除个别种之外 ,绝大多数是不同的 .所以分别立地类型组选择杉木适宜伴生种是很有必要的
According to the principle of ecological species group, the suitable cluster of Chinese fir (Cunninghamia lanceolata) species was selected from 61 potential associated species of Chinese fir in four different types of site-typed Chinese fir plantations by the fuzzy clustering method. The results are as follows, There are 8 suitable associated species in Zhongshan shading group, 8 species in low mountain and slope group, 13 species in low mountain and shady slope group, and most of the suitable species of Chinese fir Is different.Therefore, it is necessary to select the appropriate species of Chinese fir separately for the site type group
