巢湖西半湖总磷浓度对入湖总磷负荷的响应
|
摘要
巢湖富营养化问题比较严重,蓝藻水华暴发频繁。流域内人类生产及生活活动产生的一部分营养物质,随着降水、径流等方式汇入河道,流入湖泊,影响湖泊水质。通过回归分析探究了流域降雨量与各入湖河流流量关系,并在此基础上,确定入湖河流营养负荷对湖泊水质的影响。研究结果表明,南淝河的总磷入湖负荷与巢湖西半湖总磷浓度的一元线性回归拟合度最高,为0.618。研究总磷浓度对入湖河流总磷负荷的响应一方面为预测蓝藻水华暴发提供数据基础,另一方面也可为流域污染负荷控制和水源地水质管理提供决策依据。
Chaohu Lake maintained a high level of eutrophication,and cyanobacteria broke out frequently.In Chaohu Lake region,nutritive elements produced by human production and living activities were transported into inflow rivers through precipitation and runoff,which affected the water quality of the lake.The relationship between the rainfall and the river discharge was simulated by regression analysis.On this basis,the impact of nutrient loading on water quality was analyzed.The result showed that the linear regression between the total phosphorus loading in Nanfei River and the concentration of total phosphorus in the west of Chaohu Lake has the highest fitting degree of 0.618.The study on the response of total phosphorus concentration to the total phosphorus loading in inflow rivers provide the data base for predicting the outbreak of cyanobacteria bloom and the decision-making basis for water pollution control and water quality management.
