摘　　要：[目的]研究不同方式、不同时段滇池打捞的蓝藻泥中磷含量变化情况。[方法]通过对2011年滇池打捞的藻泥含磷检测数据进行统计分析,研究移动式、固定式2种不同方式在不同时段打捞的藻泥磷含量变化。[结果]滇池采用的移动式和固定式打捞的藻泥含磷量差异较大,移动式打捞的藻泥全年平均含TP 5.92 mg/kg,固定式平均含TP 3.41 mg/kg,前者是后者的1.77倍;不同时段打捞的藻泥含磷量差异也较大,6、7月份打捞的藻泥含磷量较高,到9月份含量就明显下降;全年检测数值中TP最大值和最小值移动式和固定式的各相差1.7和2.0倍。[结论]该研究结果为水污染治理中蓝藻打捞相关工作提供参考。[ Objective ] In order to study the TP content changes of the cyanobacteria mud which salvaged from Dianchi lake in different ways at different times. [ Method ] The phosphorus testing data of the cyanobacteria mud salvaged from Dianchi lake in 2011 were analyzed, the TP content changes of the cyanobacteria mud which salvaged from Dianchi lake in different ways at different times were studied. [ Result] The TP content of mobile type and fixed type salvaged eyanobacteria mud were quite different. Mobile salvaged cyanobacteria mud containing TP volume averages is 5.92 mg/kg, fixed average TP is 3.41 mg/kg, the former TP content of the latter is 1.77 times. The cyanobacteria mud salvaged in different times had quite different on TP content too. It is higher content in June to July, and lowest content in September. The annual max value of cyanobacteria mud TP content is the rain value of 1.7 （ mobile type） and 2.0 （ fixed type） times. [ Conclusion ] The results provides the reference for the salvage cyanobacteria related work in water pollution control.
