摘　　要：[目的]获得滇池蓝藻泥氮磷含量比变化规律。[方法]对2011年滇池不同方式、不同时间打捞的藻泥含氮磷数据进行统计分析。[结果]不同方式打捞的蓝藻泥氮磷含量高度相关，氮磷含量比相对稳定。移动式的藻泥氮磷含量比平均为10．5（8．6—12．3），固定式的为8．7（6．9～10．0）；移动式的蓝藻泥氮磷含量比始终高于固定式的，最高为1．49倍，最低1．07倍，平均1．22倍。[结论]移动式、固定式两种不同方式下打捞的蓝藻泥的氮磷含量比明显不同。[ Objective] In order to obtain the change rule on TN and TP content ratio of the cyanobacteria mud salvaged from Dianehl Lake. [ Method] This paper analyzed TN and TP contents of the cyanobacteria mud salvaged from Dianchi Lake in different ways, at different times of 2011. [ Result] TN and TP contents of the cyanobacteria mud salvaged by the mobile type and fixed type were highly relevant, and TN/TP ratio was relatively stable too. Average N/P ratio of mobile salvaged cyanobacteria mud was 10.5 （8.6 -12.3）, while the ratio of fixed type was 8.7 （ 6.9 - 10.0）. N/P ratio of the cyanobacteria mud salvaged by mobile type was always higher than the fixed type, up to 1.07 to 1.49 times, and the average was 1.22 times. [ Conclusion] TN/TP ratios of the cyanobacteria mud salvaged by mobile type and fixed type were different signifi- candy.
