Fall 2002 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 2002 was estimated based on allometric relationships between biomass and shoot height and flowering status derived for each site, zone, and species in October 2002. 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-0211, and allometric relationships were based on GCE data set PLT-GCEM-0211b.

本数据集针对2002年10月在10个GCE长期生态研究（Long-Term Ecological Research, LTER）采样站点的永久样地中开展的植物调查，采用2002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，对植物生物量进行估算。本次生物量估算仅针对优势物种开展，包括互花米草（Spartina alterniflora）、S. cynosuroides、柔枝灯心草（Juncus roemerianus）及稷形假稻（Zizaniopsis miliacea）。本数据集依托GCE植物监测调查数据集PLT-GCEM-0211构建，其中所使用的异速生长关系数据来源于GCE数据集PLT-GCEM-0211b。
