Comparison of the population structures between the natural forest and the high-yield forest of Phyllostachys heterocycla cv.pubescens in Wuyi Mountain.

The population structures of Phyllostachys heterocycla cv.pubescens (P.pubescens) obtained from Wuyi Mountain Nature Reserve Zone in Wiyi City and the high?yield forests in Jian'ou City were comparably analyzed.The results show that the percentages of the old age and dead bamboo are fairly high in the natural P.pubescens forest and its age structure approaches the “J” distribution while the structure of age approximates the normal distribution in high?yield forest because of the interference of farmers.The relationship between the diameter and tree height is positive in natural forest while that is not obvious in high?yield forest.The stand structure of high?yield P.pubescens forest is better than that of natural forest,and the even degree and uniform degree of high?yield P.pubescens forest are both larger than those of natural P.pubescens forest.
