摘　　要：杉木人工林是我国面积最大,蓄积量最多的人工林。通过对湖南会同森林生态系统国家野外科学观测研究站(简称会同站)杉木人工林综合观测场生物量数据的长期监测,本数据集整理了2007–2020年湖南会同杉木人工林生物量数据,具体包括树干、树枝、树叶、果(花)、树皮和气生根的干重。本数据集通过野外调查数据,结合生物量模型计算生物量。野外调查和实验流程严格遵照CERN的规范执行,数据的质量控制和评估由台站监测人员、数据管理员和分中心质控人员共同完成。本数据集的建立和共享主要为全球变化背景下杉木人工林生物量研究提供数据支持,对深入了解杉木人工林生态系统的结构和功能特征,制定合理的杉木人工林经营措施具有重要意义。Chinese fir plantation is the largest and most abundantly stocked plantation in China.Based on the long-time biomass production observation on the Chinese fir plantation comprehensive observation field at Huitong National Forest Ecosystem Research Station,Hunan(Huitong Station),this dataset collects the annual biomass production of the Chinese fir plantation at Huitong Station from 2007 to 2020,covering dry weight of trunk,branches,leaves,fruits(flowers),bark and aerial roots.In this dataset,biomass is calculated based on field survey data combined with biomass modeling.The field survey was collaboratively carried out in strict accordance with CERN specifications,and the quality control and evaluation of the data was carried out by the station monitors,data managers,and quality control personnel of the sub-centers.The establishment and sharing of this dataset mainly provide data support for the biomass production research of Chinese fir plantation under the background of global change.This is of great significance for deeply understanding the structural and functional characteristics of Chinese fir plantation ecosystem and formulating reasonable management measures for Chinese fir plantation.
