对潮滩的磷酸酶活性进行了详细的研究，包括广岛湾、秋滨公海和日本西侧九州的伊沙亚湾附近潮滩的磷酸酶活性的定位和活性的空间分布。结果表明，底泥组分的磷酸酶活性占滩涂活性的98%。此外，利用磷酸酶活力和ATP(三磷酸腺苷)生物量两个参数对19个潮间带进行了聚类分析，将其分为4类。第一组是位于远离城市地区的潮滩的一员。它们的磷酸酶活性和ATP生物量都很低，潮滩的海水非常干净。第二组为磷酸酶活性低、ATP生物量高的组。在属于这一类的滩涂中，可以观察到大量的底栖生物和贝类。第三组具有较高的磷酸酶活性和相对较低的ATP生物量。位于广岛市附近的河口潮滩属于第三类。第三类是高磷酸酶活性和高ATP生物量的潮滩。在这一组中，磷酸酶活性与ATP生物量的比率相对较低。在夏季，我们观察到最后一组潮滩的水质恶化和海底淤泥堆积。此外，我们使用多元回归分析，并提出了一个方程，以获得由磷酸酶活力和ATP生物量的测定值进行聚类分析的基团数。
Detailed studies of the phosphatase activity in the tidelands were examined including the localization of the phosphatase activities and the spatial distributions of the activity in the tidelands around Hiroshima Bay, the Aki-Bingo Open Sea and Isahaya Bay of Kyushu on the western side of Japan. The results indicate that the phosphatase activity of the sediment fraction accounts for 98% of the tideland activity. Furthermore, we classified 19 tidelands into four groups by a cluster analysis using two parameters: phosphatase activities and ATP (adenosine 5′-triphosphate) biomass. The first group is a member of the tidelands located in areas remote from the cities. They have a low phosphatase activity and low ATP biomass and the seawater in the tideland is very clean. The second is a group with a low phosphatase activity and high ATP biomass. In the tidelands belonging to this group, large numbers of benthos and shellfish can be observed. The third group has a high phosphatase activity and a relatively low ATP biomass. The estuary tidelands located near Hiroshima City belong to the third group. The last one is tidelands with a high phosphatase activity and high ATP biomass. In this group, the ratio of the phosphatase activity to ATP biomass is relatively low. In the summer, we observed deterioration in the water quality and accumulation of sludge on the sea bottom in the tideland of the last group. Moreover, we employed a multiple regression analysis and proposed an equation to obtain the group number of the cluster analysis using the assayed values of the phosphatase activity and the ATP biomass.
