摘要

摘要: 对2006年9月南黄海浮游生物网(孔径为70,160,505μm)采集样品内的浮游生物个体大小的粒径分布进行研究,确定各粒级大小的功能群组成,建立2006年秋季调查水域网采浮游生物的生物量谱,比较分析三个特征水域(黄海近岸、黄海中部及黄海和东海交汇区)的浮游生物生物量谱特征参数的异质性。结果表明:三种网采浮游生物粒级范围主要包括100 pg/个~70 ng/个的浮游植物和70 ng/个~62 mg/个的浮游动物。Sheldon型生物量谱为近似连续的波动曲线,标准型生物量谱为线型。总测区的标准生物量谱斜率和截距为-0.74和18.64,各个特征水域,黄海中部为-0.67和15.60、黄海近岸为-0.64和14.34、黄海、东海交汇区为-0.73和18.03。浮游动物种类多样性对标准生物量谱的特征参数具有较显著的影响。

Abstract: Biomass size spectrum of planktonin the southern part of the Yellow Sea were analyzed based on the samples collected with nets of 70Lm,160 Lm and 505 Lm mesh size in September,2006.The individual size compositions and functional groups of plankton were also described and compared among the different waters in the neritic,central part and transition area of the Huanghai Sea.Results showed a constant size distribution of plankton individuals including phytoplankton(100 pg/ind~70ng/ind)and zooplankton(70 ng/ind~62 mg/ind).The distributions of Sheldon type biomass size spectra were curves with apparent peak,and those of normalized spectra were linear on a double log plot.The slope and intercept of normalized biomass spectra were -0.74 and 18.64 in the total stations,and they were -0.67 and 15.60 in central part,-0.64 and 14.34 in neritic and -0.73 and 18.03 in transition part of study area,respectively.Zooplankton diversity had more influences on the parameters of normalized biomass size spectra according to the correlation analysis.
