| 摘 要： | 东平湖是山东省第二大淡水湖,具有防洪、调蓄、灌溉、生态保护等多种功能。应用狄尤模型对东平湖水环境容量进行了计算,并结合总磷、总氮现状污染负荷量,分别计算了其削减量和削减率。结果表明:东平湖总磷、总氮的现状污染负荷量大于目标要求的水环境容量,为了达到水环境保护的目标,需要削减排入东平湖的总磷、总氮;东平湖的主要污染指标为总氮,在农业生产中需要合理施肥。

| Abstract: | Dongping Lake is the second biggest freshwater lake in Shandong Province.It has the functions of floods preventing,water regulating,irrigating and ecological protecting.With the help of Dillon Model,environmental capacity,charging amount minifying amount,and minifying rate of pollutant were calculated.The results show that the charging amount of total Phosphorus and total Nitrogen exceed target environmental capacity of water body.To fulfill protecting target of hydrological environment of Dongping Lake,the recharging amount of total Phosphorus and Nitrogen should be controlled severely.For the major pollutant in Dongping Lake is total nitrogen and the nitrogen mainly comes from agricultural activity,so fertilizer proper using is important. |
