立木地上部分生物量模型的建立及其应用研究

根据杉木、马尾松、阔叶树３个树种（组）的样本资料,研究提出了一套建立立木生物量模型及其在区域性森林生物量资源清查中应用的有效方法,解决了总量与各维量间相兼容和生物量估计与森林蓄积量清查的立木材积估计相兼容的问题,而且使模型的精度和适用性相对于传统的二元立木生物量模型有明显提高。

ESTABLISHMENT AND APPLICATION OF COMPATIBLE TREE AVOVE GROUND BIOMASS MODELS

An effective method for developing a set of tree biomass models and their application in regional forest biomass inventory is presented by using the sample data of Chinese fir, Masson pine, and broad leaved tree species. This has not only provided solutions to the two major problems of incompatibility of the total biomass estimator with biomass estimators of stem, branch, leaf, etc. and that of biomass estimator with volume estimator in forest inventory, but also made the model precision much higher and applicability much better than the currently used two way tree biomass models.
