夏季南海西北部海域由外海至近岸表层海水浮游植物群落结构的空间变化
SpatialVariability inSummer Phytoplankton Community fromOffshore to Coastal Surface Waters of the Northwestern South China Sea
摘要
Abstract
Results are mainly presented about the spatial changes in phytoplankton chlorophylla(chla) concentration, community structure and picoplankton abundance (i.e.Synechococcusandpico-eucaryotes) from offshore to coastal surface waters of the South China Sea inthesummer period of 2013. Total chlaconcentration increased from 0.024 to 19.1 µg·L-1from offshore to coastal waters. Coincidingwell with chla, the proportion of microplankton (>20 µm) increased from 6.0%-81%, while that of picoplankton (<3 µm) decreased from 85% to 5.1%; andtheproportion of nanoplankton (3-20 µm) rangedduring9%-24% and showed no clear spatial change. There was a positive correlation ofSynechococcusandpico-eucaryoteabundancesthat increased towards the coastalwaters from (2.58±0.21)×106to (2.29±0.10)×108cells·L-1and from (1.62±0.91)×105to (1.83±0.46)×107 cells·L-1, respectively. In addition, our results indicatedthat the spatial variability of total surface phytoplankton biomasswasmainly regulated by picoplankton abundance in the surveyed waters.关键词
