１９９３年８和１１月，１９９４年３，５和１０月，应用荧光法测定了厦门西海域水体中各载体相（浮游植物、细菌和游离态）碱性磷酸酶活力（ＡＰＡ），结果表明：ＡＰＡ呈较为明显的季节变动，总ＡＰＡ表现为夏季（１９９３年８月）最高，春（１９９４年５月）秋（１９９３年１１月）最低；结果亦显示，该海域浮游植物和海水是碱性磷酸酶的主要载体，平均分别占４４．７％和４０．５％；与环境因子的相关分析表明，各形态磷，硝态氮、溶解氧、化学耗氧量、初级生产力、细菌生长速率（ＢＰ）对ＡＰＡ有较明显的影响；其中除ＢＰ与ＩＡＰＡ成正相关外，其余均为负相关．还对碱性磷酸酶作为水体磷状况的指示和在磷的生物地球化学循环的作用进行了初步讨论．
In August and November 1993 and March, 1994 and October 1994, the alkaline phosphatase (APA) activity of each carrier phase (phytoplankton, bacteria and free state) in Xiamen waters was measured by fluorescence spectrometry. The results showed that APA The total APA showed the highest in summer (August 1993) and the lowest in spring (May 1994) in autumn (November 1993). The results also showed that phytoplankton and seawater in the sea area were alkaline phosphatase The main carrier of enzyme was 44.7% and 40.5% respectively. Correlation analysis with environmental factors showed that the contents of phosphorus, nitrate nitrogen, dissolved oxygen, chemical oxygen demand, primary productivity and bacterial growth rate ) Had a more obvious effect on APA; among them, there was a negative correlation between BP and IAPA. Alkaline phosphatase was also initially discussed as an indicator of phosphorus status in water and as a biogeochemical cycle in phosphorus.
