| Abstract: | There are 627 species of 389 genera, including evergreen trees such as Castanopsis sclerophylla, Phoebe sheareri, Cyclobalanopsis glauca and so on, in Zinjin Mountain. The phytogeographic components of the mountain have intermediate traits between temperate and tropical zones, and there are fifteen types of distribution area, among while the northtemperate components with 83 genus (21.3%) are first in number, tropical ones totaling 83 genera (21.3%), followed by ordinary, totaling 63 genera (16.2%). Human activities, begun a long, long time age in Mount. Zinjin, have resulted in the high ratio of Therophytes (19.3) and low ratio of Phanerophytes (38.4%), the ratio of Ph. is much lower than Mount. Wuchao(74.4%), Mount. Lianhua (71.4%) in real subtropical zone, even lower than Southern Mount. Wutai (47.7%).There are 8 types of vegetation in Mount. Zijin. They are Formation Pinus rnassoniana, Form. Pinus thunbergii, Form. Liquidambar formosana. Form. Robinia pseuodacacia, Form. Dalbergia hupeana, Form. Quereus acutissima, Form. Quereus fabri and Form. Quercus varibilis. Form. Pinus masoniana, and Form. Pinus thunbergi, pioneer communities, will be replaced by Form. Liquidarnbar forrnosana, and Form. Dalbergia hupeana, which will in turn be replaced again by Form, Queraus fabri and Form. Quercus variabilis, and these last two will be relatively stable.According to principal component analysis and history records, we know soil depth, soil water, human activity and light factor are the main controlling factors in the distribution, development and succession of community in Zinjin Mountain. |
