| 摘 要： | 闽南-台湾浅滩渔场上升流区研究(1987年12月至1988年11月)及台湾海峡上升流区研究(1987年7月至1988年7月)结果表明,各种形态磷含量变化对上升流生态系具有重要作用.因此,提出以涌升水体中有机、颗粒形态磷和溶解无机态磷的相对比率来表示上升流水体的老化程度,即上升流水体老化指标(AIU)为(DOP+PP)与(DIP＋DOP＋PP)之比值.研究资料表明AIU这一表达式对于上述两上升流区是合适的,海域AIU的季节性变化与其近岸上升流的消长变化规律相一致.AIU较小的区域,其水体为新涌升水,与上升流中心位置相吻合.

| Abstract: | The results from the Minnan-Taiwan Bank fishing ground upwelling ecosystem study during the period from December 1987 through November 1988 and from the upwelling study of the central and northern Taiwan Strait in July 1987 to July 1988 show that the changes of contents of dissolved inorganic phosphorus(DIP),dissolved organic phosphorus(DOP), particulate phosphorus(PP) and total phosphorus(TP) were of an importance to the upwelling ecosystem study.Therefore, it is proposed that the aging status of a given upwelled water mass can be expressed as relative percentages of organic and paticulate species phosphorus and dissolved inorganic phosphorus, and the aging index of upwelling(AIU) is indicated by ratio of(DOP+PP) to(DIP+DOP+PP)(μmol/dm3).The oceanographic survey data show this expression of AIU was fit for the two upwelling regions mentioned.The seasonal changes of AIU in the regions correlated closely with predominating alternatively in different periods of time for the coastal upwelling.There are young upwelled waters in the areas where their value of AIU is relatively small, and it is fit for the location of the upwellinR centre mentioned. |
