摘要
本文以不同年龄、不同密度的落叶松(Larix olgensis)人工林为研究对象,基于95株标准木的树干解析和枝解析生物量数据,研究不同大小树木因子与单木各分量生物量之间的关系,应用统计分析软件建立落叶松单木各部分生物量的回归模型;利用单木各部分生物量回归模型方程估测落叶松人工林各林分的总生物量,并分析了不同年龄及林分密度下林分生物量的变化规律。研究结果表明林分的生物量随年龄的增加而不断增长,树干的生物量的比例是最大的,同时也随着年龄的增加而不断的增长,而树枝和树叶的生物量的比例较小,林分的生物量随林分密度的增加而不断增加。
In this paper, the research object is Larix olgensis Plantations of different ages and different densities, This paper bases on 95 standard wood stem analysis, analytic branches of biomass data of 19 standard sample areas, studies the biomass relation between tree factor of different size and a single wood components, and establishes biomass regression model of the various parts of larch tree by applying statistical analysis software, estimate the total biomass of larch forest by using the various parts biomass regression equations of a single wood, and analyze the change law of forest biomass of different ages and densities： Stand biomass increases with the age of the growing .tree, the proportion of trunk biomass is the largest and also increases with the age, but the proportion of the branches and leaves biomass is relatively small.
