【摘要】 湖泊富营养化是我国当前最重大的水环境问题，我国湖泊已经普遍面临富营养化问题。城市湖泊由于其特殊的地理环境，富营养化问题十分严重。双龙湖属于已经严重富营养化的城市湖泊。为对双龙湖进行科学、有效的综合防治，有必要对双龙湖的富营养化问题进行多学科综合研究。在对双龙湖湖水进行藻类增长潜力试验的基础之上，认为双龙湖是一个主要受磷控制，氮磷协同作用的城市湖泊，对其富营养化的治理主要应控制磷污染物入湖量，适量控制氮污染物入湖量，重点破坏氮、磷比的双龙湖富营养化控制路线。本文根据双龙湖在一个水文年内的水质监测资料，对多个完全混合的湖泊箱式模型进行了识别，最终选择了Canifield模型作为双龙湖的磷预测模型：P=0.8L[Z(0.0569(L2~{0.639}+QλV)]~{-1}此外，本文还对双龙湖的磷和叶绿素a之间的相关性进行了数学分析，运用最小二乘法对二者的相关模型进行了推求，最终得出双龙湖春季总磷和夏季叶绿素a相关模型：lg[chla]=1.48lg[DTP]-2.41在推求的双龙湖水质模型的基础上，本文还提出了对点源生活污水完全截流，对地面雨水径流进行资源化综合利用，建立生态净化系统、健全行政性规章制度等双龙湖水体富营养化综合防治技术方案。并对部分实施方案的治理效果进行了介绍。更多还原

【Abstract】 The lake eutrophication is the most important problem in water environment of our country .Most of our country’s lake are facing the eutrophication. Thanks to the special surroundings, all the urban lake have on the serious eutrophication status. Shuanglong lake belongs to the serious eutrophication urban lake. In order to process scientific and effective integral control, it is need to process multi-subjects integrate study on the eutrophication of Shuanglong lake. On the base of AGP experiment ,the thesis figure that the Shuanglong lake is mostly controlled by phosphorus and coordinated effect by nitrogen and phosphorus; On the control of eutrophication of Shuanglong lake, the most important measure is to control the input of phosphorus and proper control the input of nitrogen, emphases on the destroy the ratio of N/P .This thesis recognize several experience model on the base of water quality data in a year and finally select the Canifield model as the phosphorus model of Shuanglong lake :P=0.8L[Z(0.0569(L2~{0.639}+QλV)]~{-1} Moreover, this thesis process the math analysis of phosphorus and Chla, apply the regression on the study of the model of phosphorus and Chla and finally educe the model:lg[chla]=1.48lg[DTP]-2.41 On the base of model, the thesis provide the integrated control measures of shuanglong lake：complete intercept the point sourece of wastewater, utilize the rainflow, erect the zoology decotaminate system, perfect the administration et. At the same time, this article brief the harness effect of some integrated control measures.更多还原
