通过对东平湖湖区及周边土壤的采样分析，探讨了该湖水体和周边土壤中氮磷的分布情况及其影响因素，结果表明：东平湖表层水体中TN含量为0．29～11．43 mg／L，TP含量为0．019～0．459 mg／L；湖泊周边水域氮磷含量较高，而湖区氮磷含量相对较低，说明上游污染物排放和人为活动对水体中的氮磷分布有很大影响；水平空间上，土壤表层（0～10 cm）TN含量最高的是稻屯洼，王台大桥最低，TP含量都在0．05％以上；垂直空间上，东平湖湿地土壤TP垂直分布由上到下呈减少趋势，在垂直地面20 cm处TP含量出现较大转折，TP含量迅速下降，这与磷素的淋失、动植物活动及地质沉积作用有关，TN集中分布在20～40 cm土层，这与土壤对氮元素的截留、淋失、沉积作用有关。

The influencing factors and distribution of nitrogen and phosphorus were analyzed through analyzing the water N and P of Dongping Lake and the N and P in the surrounding soil. The results show that the total nitrogen (TN)in the surface water of Dongping Lake ranges from 0. 29 mg/L to 11. 43 mg/L,and the total phosphorus (TP)ranges from 0. 459 mg/L to 0. 019 mg/L. The nitrogen and phosphorus con-tents are higher in the surrounding of the lake,while it is lower in the open lake,which illustrates that both the discharge of pollutants from the upstream and the human activities has great influence on the distribution of nitrogen and phosphorus. In the horizontal dimension,the highest nitrogen content in soil surface from 0 to 10 cm is in Daotunwa,and the lowest in the Wangtai Bridge,with the phosphorus content in the six districts is more than 0. 05%. The vertical dimension,TP content of the wetland soil reduces gradually from up to down in vertical distribution. Soil TP content in 20 cm off the ground has a larger turn-the content decrease sharply,which is related to the interception of soil on leaching,activities of animal as well as plants and sedimentation effects in the soil. TN concentrates mainly in the layers of 20-40 cm,which is related to the interception of soil on nitrogen,leaching and sedimentation effects in the soil.
