| Abstract: | It is studied by field plots and statistics data analysis the vegetation structure and bio-diversity in Shenyang urban forest. The vegetation compositions are different in different type patches; There are 7 genus°(?) trees and shrubs, which quantity is more than 5% of the total trees and shrubs; The proportion between tree and shrub is 1.7 : 1, which between conifer and deciduous is 1 : 2.8; the quantity percentage of which DBH less than 20cm is more than 50%; the Margalef index (D) is relative high, but the Shannon-Wiener index and evenness index are relative low in Shenyang urban forest. |
