Fall 2022 plant monitoring survey -- biomass calculated from shoot height and flowering status of plants in permanent plots at GCE sampling sites 1-10

The biomass of plants surveyed in permanent plots at 10 GCE LTER sampling sites in October 2022 was estimated based on allometric relationships between biomass and shoot height and flowering status derived for each site, zone, and species in October 2002 and October 2008. Biomass was calculated for dominant species, including Spartina alterniflora, S. cynosuroides, Juncus roemerianus, and Zizaniopsis miliacea, as well as rarer species including Scirpus spp, Panicum spp. And Typha angustifolia. This data set is based on GCE plant monitoring survey data set PLT-GCEM-2111a, and allometric relationships were based on GCE data sets PLT-GCEM-0211b, PLT-GCEM-0711, and PLT-GCEM-2011.

2022年10月，研究人员对10个GCE LTER采样站点内的永久样地开展植物调查，并基于2002年10月与2008年10月针对各站点、区域及物种推导得到的生物量与株高、开花状态间的异速生长关系（allometric relationship），完成了本次调查植物的生物量估算工作。本数据集为优势物种与稀有物种均计算了生物量，其中优势物种包括互花米草（Spartina alterniflora）、S. cynosuroides、Juncus roemerianus及Zizaniopsis miliacea，稀有物种包括藨草属（Scirpus spp.）、黍属（Panicum spp.）及狭叶香蒲（Typha angustifolia）。本数据集依托GCE植物监测调查数据集PLT-GCEM-2111a构建，其异速生长关系则基于GCE数据集PLT-GCEM-0211b、PLT-GCEM-0711及PLT-GCEM-2011生成。
