%X The mineralization experiment of dissolved organic phosphorous was carried out in the filtered water samples collected in Wudalianchi Lake, in October, 2010.The concentrations of dissolved reactive phosphorus (DRP), dissolved organic phosphorous (DOP) and microbial number were analyzed by continuous sampling. The research showed that in the mineralization process, in the three sampling stations (W3SB, W3XB, W5B), the DRP concentrations of W3SB and W5B were similar, and generally higher than that for W3XB, the DRP concentration showed an upward trend, increasing by 50.00 times (W5B), 29.00 times (W3XB), 2.50 times (W3SB), respectively. The DOP concentration showed a downward trend, decreasing by 85.58% (W3XB), 77.83% (W5B) and 68.00% (W3SB), respectively. The mineralization rate of DOP also showed a downward trend, the mineralization rate of W5B was significantly higher than that for W3SB and W3XB, the largest mineralization rate of DOP of W5B was 14.10×10-4 mg·(L·d)-1. The microbial number showed an upward trend. The positive correlation was found between the microbial number and DRP concentration (r=0.528, P<0.05), the negative correlation was found between the microbial number and DOP concentration (r=-0.482, P<0.05).
