Study of Flora in Zhangguangcai Mountains

This paper is a study on flora of field through investigation and statistics analysis in Zhanggunacai Mountains.The results show that there are 708 species of vascular plants which belong to 316 genera and 91 families in Zhangguangcai Mountains.Families including 11~30 species,those belong to 12 families,84 genera and 218 species,had the most genera and species compositions of vascular plants.Families including 2~5 species have the highest ratio,it is 39.56%.Plant species of compositae is the richest,totalling to 37 genera and 94 species.The world distributional family of vascular plants is dominant in the family distributions,and the seconds are general tropical distribution and the north temperate distribution.The temperate distribution is abundant in the genera distributions of vascular plants,there are totally 208 genera and 461 species.Except world distribution,the proportion of northern temperate distribution genera and species are about 46.10% and 56.81% in the rest species,and 59.62% and 68.76% in the temperate distribution.
