摘要:

为准确预测马尾松纸浆商品材生物量和确定最佳利用时间,用12块样地108株不同立地、不同造林密度、不同林龄林分径阶生物量标准木,建立了单株各器官、地上部分及各种规格商品材生物量预测方程。用各类试验林和解析木资料建立了生长收获模型系统。经检验,生物量和林分生长预测方程的预测结果与实际基本吻合。依据生物量和林分生长预测方程,编制了6种不同造林密度、14~20指数级林分主要测树因子、林分树干和各种规格商品材生物量的生长过程表。使经营单位可根据利用单位的要求,调整造林密度和经营方式及最佳利用时间。分析了不同立地、不同造林密度各种生物量的生长和结构变化规律。

Abstract:

In order to forecast commercial biomass of the Masson pine pulpwood and determine optimum utilization time accurately, the commercial biomass forecast equations of various organs, above ground parts, various specifications of individual tree were established using the data of 12 sample plots and 108 sample trees on various sites, various planting densities, and at various stand ages.Growth yield model system was established using data of various trial stands and stem analysis.The forecast result of biomass and stand growth by the equations was consistent with the actual situation.According to the forecast equations of biomass and stand growth, commercial timber yield table of main stand factors, stand stem and various specifications had been compiled, which were at 6 planting densities and 14 ~ 20 site indexes.According to the demand of utilization unit, the management unit may regulate the planting density, management manner and optimum utilization time.Dynamic of biomass growth and structure of Masson pine pulp wood on various sites and various planting densities were analysed.
