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, PLT-GCEM-0711, and PLT-GCEM-2011.2014年10月，研究人员对10个GCE长期生态研究（Long-Term Ecological Research, LTER）采样样地内的永久样方开展植物调查，并基于各研究样地、分区及物种在2002年10月与2008年10月建立的生物量与株高、开花状态间的异速生长关系（allometric relationship），估算了调查植物的生物量。本次生物量估算涵盖了互花米草（Spartina alterniflora）、犬尾米草（Spartina cynosuroides）、罗默蔺草（Juncus roemerianus）以及水茅（Zizaniopsis miliacea）等优势种，同时也包含了藨草属（Scirpus spp.）、黍属（Panicum spp.）与狭叶香蒲（Typha angustifolia）等稀有种的生物量。本数据集依托GCE植物监测调查数据集PLT-GCEM-1403a构建，所采用的异速生长关系源自GCE数据集PLT-GCEM-0211b、PLT-GCEM-0711及PLT-GCEM-2011。
