Fall 2009 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 2009 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 only calculated for dominant species, including Spartina alterniflora, S. cynosuroides, Juncus roemerianus, and Zizaniopsis miliacea. This data set is based on GCE plant monitoring survey data set PLT-GCEM-1004a, and allometric relationships were based on GCE data sets PLT-GCEM-0211b and PLT-GCEM-0812a.

2009年10月，针对10个GCE LTER采样站点内的固定样地开展植物调查，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（allometric relationships），估算得到本次调查植物的生物量。本数据集仅针对优势物种计算生物量，涵盖互花米草（Spartina alterniflora）、S. cynosuroides、Juncus roemerianus与Zizaniopsis miliacea。该数据集依托GCE植物监测调查数据集PLT-GCEM-1004a构建，其所采用的异速生长关系源自GCE数据集PLT-GCEM-0211b与PLT-GCEM-0812a。
