| Abstract: | In order to examine the basic site conditions needed for the normal growth of Chinese pine plantations and maintenance of high biodiversity,97 plots of Chinese pine plantations and 134 shrub-herb sub-plots were established in the Beijing low mountain areas.The diameter of pine trees and species diversity were measured under four different site conditions.The results showed that diameter structure of Chinese pine plantations showed a normal distribution at the north and northeast slopes with deep soils,while... |
