摘要:
为有效提高城市雨洪模型的建模质量,在传统水文分析方法的基础上,结合多级汇水区的空间认知理念,提出了顾及多要素的城市地表汇水区分级划分方法. 该方法综合了地形、河流、建筑物、道路及人工排水设施等不同层次的要素,将城市地表作三个等级的划分,由大到小,逐级细化,并采用丽水市莲都区雨洪模型进行模拟实验,结果表明分级划分法所得汇水区分别在SWMM模型与MOUSE模型中的模拟结果均比泰森多边形法的更加准确,在实地考察对比后发现,该方法划分结果基本符合实地真实汇水情况,证实了其能够应用于较复杂的城市汇水区划分,可为城市防洪减灾研究和灾后恢复工作提供指导.
Abstract:
In order to effectively improve the modeling quality of urban stormwater models,the urban land surface watershed hierarchical partition method that took into account multiple factors has been proposed in this paper which was based on traditional hydrological analysis methods and the spatial cognition concept of multi-level catchment area was combined. The method incorporated different levels of elements such as terrain,rivers,buildings,roads,and artificial drainage facilities,and the urban land surface was divided into three levels according to the principle of large to small as well as step-by-step refinement. The rain flood model was experimentally carried out in Liandu District of Lishui City,China. The verification results showed that the simulation results obtained by the hierarchical partition method in the SWMM model and the MOUSE model were more accurate than the Thiessen polygon method. After field comparison,it was found that the method results were consistent with the actual real water situation basically in the field. The method has been proved to be applicable to the more complicated urban catchment division,and it could provide reference for urban flood control and disaster reduction research,as well as guide disaster recovery work to a certain extent.
