摘　　要：雨水景观利用是雨水资源化的重要途径,而准确模拟雨水景观利用对景观水体的水质影响是制定方案的基础和依据。以华北地区某生态小城镇(HM镇)作为研究对象,首先基于SWMM暴雨管理模型,建立了HM镇的雨水径流模型,并对不同降雨重现期下HM镇的雨水径流进行了模拟;然后,以景观河作为HM镇汇流雨水排放的受纳水体,采用WASP水质模型模拟了雨水排放至景观河后的水质变化。研究表明,综合运用SWMM和WASP可以模拟出雨水从降水到用于景观利用的整体过程,为建设雨水资源化工程和制定雨水污染治理措施提供了决策依据。Rainwater landscape use is a significant utilization of rainwater. Accurately modeling the influence of rainwater landscape use on the landscape water quality is the foundation of a project draft. Using HM town in northern China as an example, a rainfall runoff model was established based on the SWMM model and runoff in different rainfall return periods was modeled. Next, landscape river was used as the receiving water body of the catchment rainwater of HM town. The WASP model was used to simulate water quality variation of the landscape river when catchment rainwater was discharged. The study showed that SWMM combined with WASP could model the whole rainwater process from rainfall to its use as a source of landscape water. Findings could also provide decision support for the construction of rainwater resource utilization projects and the preparation of rainwater pollution treatment measures.
