The number of the species rank the second compared with thosein the Hualong reserve. The spotes, Pterostyrax Psillophylla,is found to be a new recordin Qinling mountain.The characteristics of the areal-type and the similarity coefficient betWeen different reserves indicate there is a special feature in the Changqing Reserve where both the northern and the outhem plant types grow together. In addtion, 16 speciesexcept the 30 are provincially protected plants. accounting for 32% of the total. |
