摘要
本文根据103块标准地材料,并利用其103株平均木解析木,分析了不同年龄、不同密度对杉木人工林生物量的影响及不同器官生物量间的相互关系。利用不同的数学模型,探讨了生物量与胸径,树高及树干生物量与材积的回归关系,求出了各器官生物量的最佳估测模型。
Based on 103 average sample trees and 103 plots, the effects of different ages and densities on the biomass of the Chinese fir plantation, and the correlations among the biomass of different organs were analysed. Using 20 regression equations, the regression relations of biomass to diameter (D) and height (H), and stem biomass to volume were discussed. The fittest regression equations for the biomass of various organs were given.
