The primary experiment shows that: The trend of APA in the sediment was coincident with the dissolved phosphorus(DP), but high concentration of DP will restrain APA to a certain extent.
初步的研究表明：西湖沉积物中的碱性磷酸酶活性和底泥中溶解性磷的变化趋势基本一致，但高浓度的溶解性磷对APA产生一定的抑制作用；
The experiment showed that the absorption intensity was much greater than the release intensity in higher phosphorus concentration of upper water of surficial sediment.
可以看出当上覆水磷酸盐浓度较高时，吸附作用的强度远大于释放作用。
At the appropriate temperature conditions, when water phosphorus concentration is low or zero, APA role of phosphorus from sediment in the water release for the use of algal growth and reproduction.
在适宜温度条件下，当水体中磷浓度较低或为零时，APA作用使得底泥中的磷向水体中释放，供藻类生长繁殖利用。
