| Abstract: | Based on the investigation of vegetation plant diversity in Zhouzhi Nature Reserve,1 088 spermatophyte species, belonging to 522 genera and 121 families have been discovered, among which 465 were woody species, and 623 herbaceous species, with 504 endemic species in this area and 46 species in danger of extinction. The rich vegetation resources could be divided into 10 types according to different purposes such as ornamental, edible, medical, etc. As Zhouzhi is located in the Qinling Mountains, altitudinal distribution of the vegetation was remarkable, and different ecosystems types could be found there. Being the main body of the ecosystem and the support of bio diversity, forest is 53 066 hm 2, accounting for 94% of the total. Based on this, relative measures for bio diversity conservation are proposed. |
