武夷山毛竹天然林与人工林种群结构比较研究

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

  • 摘要: 对武夷山国家级自然保护区与建瓯毛竹丰产林毛竹种群结构特征比较研究结果表明,毛竹天然林中老龄及枯死竹占比例较大,年龄结构呈“J”型分布,而毛竹人工林年龄结构由于成熟竹材的人为砍伐则近似正态分布;毛竹天然林胸径和树高分布相关性较人工林显著,但人工林林分结构比天然林理想,其均匀度、整齐度均大于天然林。

     

    Abstract: 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.
