【摘要】 以灰金竹种群结构和产量的关系为研究对象。分析相同立地条件下竹林的年龄结构,水平结构,垂直结构与产量的关系。结果表明:在竹林内部,以1~3年生竹且各龄竹株的数量百分率趋于相近时,竹林产量高。林分立竹密度在37500株/hm2~52500株/hm2之间为宜;竹株分布越均匀,竹林产量越高;竹林冠层高度越高,林分产量越高。更多还原

【Abstract】 This paper is concentrated on the relationship between the population structure and the output of Phyllostachys nigra var.henosis.Making an analysis of the relationship between age structure,the level structure,the vertical structure and the output in the same site condition.The results show:in the inside of bamboo grove,When the percentage of every age in 1 ~ 3 years old tends to become similar,the production is higher.Forest density of bamboo is suitable in 37500 plants/ hm2 ~ 52500 plants/hm2,the more uniform density of the bamboo,the higher the yield;the higher the Canopy height,the higher the yield.更多还原
