| 摘 要： | 为进一步了解湖泊表层水中磷形态的季节变化特征,在2009年7月（丰水期）和11月（平水期）、2010年3月（枯水期）连续监测长寿湖水中不同形态磷的含量,分析磷形态含量与水质参数之间的相关关系。结果表明,各个水期长寿湖水中的总磷（TP）都以溶解态磷（DTP）为主要存在形式,DTP在丰水期与平水期以可溶性正磷酸盐（DP）为主要存在形式,在枯水期以溶解性有机磷（DOP）为主要存在形式。总体来说,长寿湖水中TP和DTP含量呈现枯水期〉丰水期〉平水期;DP含量呈现丰水期〉平水期〉枯水期的季节变化特征。相关关系分析发现,磷形态含量与湖水的溶解氧（DO）和电导的相关性明显,与pH和高锰酸盐指数无明显的相关关系。 |

| Abstract: | To further understand the characteristics of seasonal variation of phosphors species in lake surface water,the contents of phosphorus species in water of Changshou Lake were continuously monitored in July,2009(high-water period),November,2009(normal-water period),and March,2010(low-water period),and the correlations between phosphorus species and water quality parameters were also analyzed.The results showed that dissolved total phosphorus(DTP) was the main existing forms in total phosphorus(TP) in the lake... |
