PRELIMINARY STUDY ON THE AGE STRUCTURE OF FARGESIA DRACOCEPHALA POPULATION IN BAISHUIJIANG NATURE RESERVE

Huang Huali (Division of Baishuijiang Nature Reserve, Ministry of forestry)  
In the paper, appling the method of "statie state life table", the dynamic states of the age structure of Fargesia dracocephala population in Baishuijiang Nature Reserve have been discussed. There are 5 types of age structure, the minimum live ages of bamboo whips and culms are different within different types of age structure. The general trend of this population will be flowering and death.The laws of the age structure of Fargesia dracocephala stable population; The 1-4 year old culm numbers account for 70% of the total culms, and each age culm numbers of 1-4 year old account for 16-20% of the total culms. The obvious factor resulting in the dynamic change in the age structure of Fargesia dracocephala population in the Baishuijiang Nature Reserve is itself.
