| 摘 要： | 应用（３２）Ｐｉ同位素稀释法，测定了外加溶解有机磷化合物（ＤＯＰ）对浮游植物和细菌吸收（３２）Ｐｉ的影响．结果表明：厦门海域浮游植物和细菌均能不同程度地利用ＤＯＰ，从抑制程度（百分率）来看，浮游植物对ＤＯＰ的利用能力大于细菌；在多数情况下，随ＤＯＰ浓度升高，抑制程度增大，表明浮游植物吸收ＤＯＰ增加．

| Abstract: | The availability of six dissolved organic phophorus (DOP) to serve as P sources for natural phytoplankton and bacterioplankton was examined by measuring the degree to which the DOP decrease uptake of orthophosphate (32Pi). The results showed that both phyto plankton and bacterioplankton could uptake DOP with different degrees,the uptake of DOP by phytoplankton was greater than that by bacterioplankton in Xiamen seawaters. For phytoplankton,the inhibition degree increased with increasing the DOP concentration in most cases,suggesting that uptake of DOP by phytoplankton increased. |
