| 摘 要： | 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

| Abstract: | This paper deals with the selection of optimal accompanying tree species for Chinese fir from 61 potential mixed tree species in the natural mixed stands which are habitat in four kinds of groups of site type by means of Fuzzy cluster according to ecological species group's theory. The result was as follows: There were 7 optimal accompanying tree species for Chinese fir in mid mountain sunny side exposure, there were 5 optimal accompanying tree species for Chinese fir in mid mountain shade side exposure, there were 8 optimal accompanying tree species for Chinese fir in lower mountain sunny side exposure, and there were 8 optimal accompanying tree species for Chinese fir in lower mountain shade side exposure. It was suggested that the most accompanying tree species would be various in different groups of site type except the very few species, and it was necessary to select the optimal accompanying tree species separately for different group of site type. |
