Based on the monthly investigations of different forms of phosphorus(P) and algae growth from January to December 2013 in Meiliang bay of Taihu Lake, the transformation of different P forms and the relationship between different P forms and algae growth was investigated under the dual conditions of disturbance due to wind and wave and algae growth. Results of the total P(TP), particulate P (PP), dissolved total P(DTP), dissolved inorganic P(DIP) and bioavailable P(BAP) showed that the monthly concentrations reached the maximum in summer and autumn while the minimum in winter and spring. In addition, the algae growth showed the same trends as above. However, no variation was found in the dissolved organic P(DOP) and bioavailable particulate P(BAPP). The bioavailability of PP was only 12.75% from June to October, which was obviously lower than the annual mean (37.14%). It was attributed to the acceleration on the transformation of PP to DTP due to the immobilization of sedimentary P under sediment disturbance and algae adsorption. The percentage of DTP in BAP was up to 69.33% (average), which was obviously higher than the percentage of bioavailable PP (30.66%, average) and the annual mean (56.63%) of DTP during the interval. In addition, the algae bloom appeared in the interval.
基于2013年1月至12月对太湖梅梁湾不同形态磷（P）及藻类生长的月度调查，研究了风浪扰动和藻类生长双重条件下不同磷形态的转化及其与藻类生长的关系。总磷（TP）、颗粒态磷（PP）、溶解性总磷（DTP）、溶解性无机磷（DIP）和生物可利用磷（BAP）的结果表明，其月浓度在夏秋季节达到最高，而在冬春季节最低。此外，藻类生长呈现出与上述相同的趋势。然而，溶解性有机磷（DOP）和生物可利用颗粒态磷（BAPP）未发现变化。6月至10月期间PP的生物可利用性仅为12.75%，明显低于年平均值（37.14%）。这归因于沉积物扰动和藻类吸附作用下，沉积磷的固定作用加速了PP向DTP的转化。该时段DTP在BAP中的占比高达69.33%（平均），明显高于生物可利用PP的占比（平均30.66%）以及该时段DTP的年平均值（56.63%）。此外，该时段出现了藻类水华。
