摘要: 利用2004年夏季台湾海峡南部海域的现场激光粒度仪剖面测量数据,运用海洋食物链的粒径谱理论,分析了悬浮颗粒物的Sheldon谱图和正态化谱图的剖面分布精细结构。横跨台湾海峡沿岸及浅滩外斜上升流的A和B两断面Sheldon粒径谱类型相近,正态化谱图的斜率r的范围从-0.79到-0.65,在明显高于寡营养海域的水平上波动。斜率r的高值带或高变幅带,在上升流系高叶绿素带及叶绿素最大层的周边或前端的呈斑状分布。海洋食物链的粒径谱分析结果支持关于台湾海峡南部上升流生态系高生产力、短食物链和高营养转换效率的宏观认识,并深化对营养转换效率分布精细结构的了解。现场激光粒度仪可发展为探索海洋食物链时空分布精细结构的常备传感器。Abstract: Based on size spectrum theory,field data measured by laser particle size analyzer were used to analyze Sheldon size spectra and normalized size spectra of suspended particle in the southern Taiwan Strait during summer,2004. The results showed that the patterns of Sheldon size spectra were similar at all stations in transects A and B. In normalized size spectra,the range of slopes was -0.79 to -0.65. Influenced by coastal upwelling of Taiwan Strait and upwelling around the Taiwan Shoal,the slopes were high around the high chlorophyll area or the chlorophyll maximum layer. This indicated that the process of up-welling was in favor of developing locally of biological food chain with high trophict ransfer efficiency. The in situlaser particle size analyzer could beregar ded as a basic sensor to detect finestructure for trophic transfer efficiency.
