摘　　要：以荻泽联圩为研究对象,应用SWAT模型模拟太湖流域典型圩区农业非点源产污规律,建立了研究区域的非点源污染基础信息库,实现了流域的空间参数化过程;将参数化过程中提取的模型参数纳入到数据库中统一管理,按照模型要求建立了数据库字段和参数内容的对应表,解决了模型运行时众多离散单元的自动赋值问题;采用虚拟水库控制技术,解决了SWAT模型在控制出流的圩区中的应用弊端。The SWAT model was applied to polder areas to simulate the behaviors of non - point agricultural sources in the Lake Taihu Watershed. For this purpose, a non - point source pollution information database was established and the data extracted from the parameter process was integrated into the database. A table was set up within the database to build linkage between data fields and parameters, resolving the problem of automatic assignment of numerous discrete elements. The drawbacks of SWAT model used in the polder areas were overcome with the dummy reservoir technology.
