摘要
抚仙湖是我国战略性水资源储备库,星云湖是与其一衣带水的湖泊,二者水质和水生态环境保护治理工作受到国家高度重视。为明确抚仙湖-星云湖流域水污染特征并提出有针对性的污染控制对策,该研究对流域的污染特征进行分析。研究表明,近20年来,抚仙湖和星云湖水体中氮、磷污染指标浓度都呈现上升趋势,这与流域面源污染负荷的产生量和入湖量显著增加相关。流域内的氮、磷主要污染源均来自于农田面源、农村生活污染水和畜禽粪便。根据氮、磷负荷排放特征,识别出流域内的氮磷污染高风险区,并结合流域内已有的氮磷污染防治措施现状,进一步提出以空间管控和生态修复为核心的流域氮磷污染控制对策及措施。
Fuxian Lake is one of the water resource strategic reservoirs in China,Xingyun Lake is connected to Fuxian Lake.Chinese government has paid a high attention to their protection and management in water quality and their aquatic ecological environment.In order to understand the pollution characteristics of this area and propose some targeted countermeasures,this research investigated the variation of pollutions of the two lakes.Results showed that the nitrogen and phosphorus were the main pollution factors,and the concentration of them has showed an increasing trend in the past twenty years.The nitrogen and phosphorus mainly came from the farmland non-point source,the rural domestic sewage and the livestock wastewater.Based on the discharge characteristics of nitrogen and phosphorus in this area,the high-risk areas of nitrogen and phosphorus pollution were identified and the prevention and control countermeasures of the nitrogen and phosphorus pollution were put forward,focusing on spatial management and ecological restoration.
