本文采用标准地、标准木和树体分层分段抽取标准样品的方法,测定了青海云杉林木不同部位的含水率、干重比、公顷容重,最后计算出树体各部位的生物量和公顷生物量,并建立了有关的数学模型。该研究提供了青海云杉林在64年生时不同立地条件、林分特征、培育方式和经营强度下的生物量。它为今后全面测定青海云杉林的生物量和生产经营管理提供了一定的科学依据。
In this paper, standard, standard wood and tree stratified by standard methods of sampling, determination of the different parts of Qinghai spruce trees moisture content, dry weight ratio, hectare bulk density, and finally calculate the biomass of various parts of the tree and Ha biomass, and established the relevant mathematical model. The study provided the biomass of the Picea crassifolia forest at 64 years old under different site conditions, stand characteristics, cultivation methods and management intensity. It provides a scientific basis for the comprehensive determination of the biomass and production and management of Picea crassifolia in the future.
