A STUDY ON THE POPULATIONAL STRUCTURE AND THE TRENDS OF RHODODENDRON DELAVAYI IN BAILI AZALEA FOREST

Baili Azalea Forest is a characteristic natural landscape and plant community in the west of Guizhou. In the cominunity, the Rhododndron delavayi is a main species of architectural complex. On the level of population, the paper studies and discusses the dynamic regularity and tendency of evolution of Rhododendron delavayi that based on size class, density, structure of age and pattarn of distribution in different habitat. So that achieve the goal of draning inferences about other cases from one instance for understanding tendency of development and evolution, and put forward some theoretial basis and data of decision for protection and using of the natural landscape.
