Abstract:The composition and activity of alkaline phosphatase in waters with different PO3-4-P concentrations were studied experimentally. The results show: ①The total alkaline phosphatase activity (TAPA) was decreased with the increase of PO3-4-P concentration(r=-0. 586, n=55).Based on the statistic analyses, when PO3-4-P concentrations were between 0 to 0. 010mg· L- 1,no significant difference was found in the TAPA. When PO3-4-P concentrations exceeded 0.010mg·L-1, the TAPA was significant difference (P<0.01). ②The contents of APA in phytoplankton(PAPA), bacteria (BAPA) and dissolved (DAPA) were different. The ratio of DAPA to TAPA was the highest and BAPA was the smallest. ③With the increasing of PO43-4-P concentration, the PAPA decreased. When PO3-4-P concentrations were between 0 to 0.020mg·L-1, over 0. 020mg·L -1 and over 0.200mg·L -1, the PAPA were no significant, significant(P<0.05) and highly significant, respectively (P<0.01). ④The BAPA showed no significant relationship with the PO3-4-P concentration.
