森林生物量是森林生态系统的最基本数量特征 ,生物量数据是研究许多林业问题和生态问题的基础 ,因此 ,准确测定生物量十分重要。建立生物量模型是生物量估测的主要手段。以往所建模型 ,存在一个严重的缺陷 ,即总量与分量模型不相容。如何解决相容性问题 ,一直是生物量估计领域所面临的一个难题。本文引入线性联立方程组方法 ,较好地解决了相容性问题 ,并使模型的预估精度和适用性较以往生物量模型有了显著提高。
Forest biomass is the most basic quantitative characteristic of forest ecosystem. Biomass data is the basis for studying many forestry and ecological problems. Therefore, it is very important to measure biomass accurately. The establishment of biomass model is the main means of biomass estimation. The model built in the past, there is a serious flaw, that is, total and component models are not compatible. How to solve the compatibility problem has always been a challenge in the field of biomass estimation. In this paper, the method of linear simultaneous equations is introduced to solve the problem of compatibility well, and the prediction accuracy and applicability of the model are significantly improved compared with the previous biomass model.
