摘要
林木生物量模型回归估计法是林分生物量测定的常用方法之一,林木生物量模型的研究对森林生物量的研究及其估测有重要价值。随着森林碳储量的研究,森林生物量再次被重视,其精度要求也随之提高。介绍了林木生物量模型历史和现状,对生物量模型类型、参数估计方法、模型评介指标,模型中的异方差、不兼容等问题及其解决方法作了简介,概括了当前国内的一些新进展,并对未来的发展趋势作了预测。
Tree biomass model is one of the methods of estimating stand biomass, and it is very important to study and estimate the forest biomass. Depending on the study of carbon storage, forest biomass has attracted again, and the precision requirement is increasing. The development and status of tree biomass models were presented. The types of biomass models, parameter estimation, evaluation indexes and the problems of heteroscedasticity and incompatibility in tree biomass models and the solving methods were pointed out. Furthermore, the paper generalized some new developments, and the research tendency of tree biomass models which are applied in forestry was discussed.
