Fall 2014 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 2014 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-1403a, and allometric relationships were based on GCE data sets PLT-GCEM-0211b and PLT-GCEM-0812a.

2014年10月，对10个GCE LTER采样站点永久样地内调查获取的植物生物量，基于2002年10月与2008年10月针对各站点、区域及物种建立的生物量与株高、开花状态间的异速生长关系进行了估算。本次研究涵盖的物种包含优势物种与稀有种群：优势物种包括互花米草（Spartina alterniflora）、狗尾草状米草（S. cynosuroides）、美洲灯心草（Juncus roemerianus）与玉蜀黍状水禾（Zizaniopsis miliacea）；稀有种群包括藨草属（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-1403a构建，其所使用的异速生长关系源自GCE数据集PLT-GCEM-0211b与PLT-GCEM-0812a。
