| 摘要: |
| 根据1988年7月调查资料讨论了台湾海峡中北部海域夏季上升流区各种形态磷的分布特征。结果表明,上升流中心区(即海坛岛东侧一带水域)具有低温、高盐、低溶解氧;DIP, TDP, PP, TP较高;DOP较低(0.27);及DIP/DOP比值(约为1)较高的特性。DOP是该海域磷的主要形态(占TP的49.2％),其含量分布及其形态转化与生物活动直接相关,是该海域生物生产力高的体现。 |

| Abstract: |
| The distribution of dissolved inorganic phosphorus (DIP), dissolved organic phosphorus (DOP), total dissolved phosphorus (TDP), particulate phosphorus (PP) and total phosphorus (TP) in summer in the upwelling area of the central and northern Taiwan Strait were studied. The results showed that the high phosphorus waters (DIP > 0.2, TDP > 0.5, TP > 0.7) upwell to the surface layer in the eastern of the Haitan Island, where is the location of the upwelling centre with relatively low temperature, high salinity and low dissolved oxygen. There are relatively high DIP, TDP, PP and TP, low DOP (0.27) and high ratio of DIP/DOP (ca. = 1) in the upwelling centre. DIP, TDP, PP and TP evidently show positive correlation with temperature and negative correlation with salinity, but the correlations between DOP and T or s were on the contrary. DOP is major species of phosphorus in the area (49.2 percent in TP). The content and distribution of DOP were related with the biological activities, showed there is high productivity in this upwelling area. |
