摘　　要：生物量模型是估算各种时空尺度树木和森林生物量最常用的方法,具有破坏少、使用简便且相对精度高等优点。常绿落叶阔叶混交林作为我国亚热带地区重要的植被类型,其生物量模型的系统性汇编至今仍未见报道。本研究通过对鄂西南地区28.9 hm2常绿落叶阔叶混交林固定监测样地的清查,编制物种名录,并以此检索、收集和建立常绿落叶阔叶林木本植物生物量模型数据集。共包含167组665个生物量模型及模型对应的植物种名、拉丁名、植物生活型、模型计算的植物组分、模型自变量、自变量计量单位及范围、模型相关系数或决定系数、模型样本数、模型所处气候带和土壤类型等信息。本数据集的建立,可为深入研究该类型植被的生产力及碳汇研究提供基础资料,也可为该类森林的管理、生物多样性保护和森林生态效益的评价等提供科学依据。Tree biomass equations are the most commonly used method to estimate tree and forest biomass on various spatial and temporal scales because of their minor damage,ease of use,and high relative accuracy.The systematic compilation of models for the biomass of mixed evergreen and deciduous broadleaved forest(a unique and essential class of typical vegetation types in the subtropical zone of China)has not been reported so far.In this paper,we compiled a species list through an inventory of 28.9 hm2 of mixed evergreen deciduous broad-leaved forests in southwestern Hubei Province with fixed detection sample plots,produced a species list,and used it to retrieve,collect and establish a model dataset of woody plant biomass in subtropical mixed evergreen and deciduous broad-leaved forests.The species list contains a total of 665 biomass models in 167 groups as well as the information corresponding to each mode,such as the plant species name,Latin name,plant life type,plant components calculated by the model,model independent variables,measurement units and ranges of independent variables,model correlation coefficient or coefficient of determination,model sample size,climate zone,and soil type.is also recorded.By establishing this dataset,this paper not only provides essential information for in-depth research on the productivity and carbon sink of this specific vegetation but also serve as a scientific basis for the management of this type of forest,the conservation of biodiversity,and the evaluation of forest ecological benefits.
