| 摘 要： | 通过建立及求解二维水流水质模型,提出了基于水质模拟的湖泊型饮用水水源保护区的划分方法.以太湖贡湖流域为例,根据《饮用水水源保护区划分技术规范》(HJ/T338—2007),在研究二维水流水质模型的基础上,建立贡湖流域二维水流水质模型.将望亭立交调水情况作为重要影响因素,以高锰酸盐指数、总氮、总磷作为主要水质指标,模拟并分析贡湖湖体2010年不同调水情景模式下的水质变化.应用贡湖流域水流水质模拟结果和GIS分析方法,采用数值分析法划分贡湖水源地一、二级保护区,对贡湖饮用水水源保护区做出准确的划分,为贡湖流域的饮用水水源地保护提供切实可用的技术支持.

| Abstract: | This paper describes the general principles and research methods of delineating source water protection areas based on the two-dimensional flow-pollutant model.Taking Gong Lake as an example,the two-dimensional flow-pollutant model of Gong Lake was first built and run according to Delineating Source Water Protection Areas(HJ/T338—2007).The water transfer in Wangting hub was regarded as the main impact on water quality in Gong Lake,and the water quality indexes such as CODMn,TP and TN in different situations were analyzed in 2010.Then numerical simulation was used to delineate source water protection area on the basis of the two-dimensional flow-pollutant model and GIS method.The study results provide the technical support for delineating source water protection areas. |
