摘要
介绍及比较了当前灌木生物量研究中较为常用的5种方法:样方法、平均木法、相对生长法、数量化法和非破坏性方法,对影响灌木生物量的环境因子和影响灌木生物量测定的测树因子的研究成果进行综述,最后介绍和讨论了灌木生物量预测模型的变量选择、精度评价指标和选型等问题.
The paper introduces and compares five methods commonly used in the research of shrub biomass estimation including plot method, mean sample timber, relative growth method, quantitative and non-destructive method. Meanwhile, it elaborates the research achievement with regard to environmental factors influencing shrub biomass and tree-measurement factors influencing biomass estimation. At last, it discusses the problems concerning variable selection, accuracy evaluation index and model selection of shrub biomass prediction.
