摘　　要：江苏省太湖地区地处长江三角洲地区,河网密布,城镇化率高,水利工程众多且调度复杂,流域、区域、圩区等特点明显,区域防洪、城市防洪排涝、圩区排涝等问题比较突出。由于平原河网水动力模拟模型有其内在的复杂性,大型平原河网的水文—水动力联合模拟通常难以满足模型数据动态更新和多尺度分级模拟要求。利用多尺度智能模型构建思路,针对江苏省太湖地区洪涝问题开展多尺度智能分级模型的构建与模拟,结果表明,多尺度模型能够快速模拟江苏省太湖地区洪涝情况,为江苏省太湖地区洪涝精准调度提供有力支撑。Taihu Lake area of Jiangsu Province is located in the Yangtze River Delta,with a dense river network,high urbanization rate,numerous water projects and complex regulation,obvious characteristics of river basins,regions and polder areas,and prominent problems such as regional flood,urban flood and drainage,and polder area drainage.Due to the inherent complexity of the hydrodynamic simulation model of plain river network,the hydrological-hydrodynamic joint simulation of large plain river network is usually difficult to meet the requirements of dynamic update of model data and multi-scale hierarchical simulation.This paper uses the idea of multi-scale intelligent model construction to carry out the construction and simulation of multi-scale intelligent hierarchical model for flooding in Taihu Lake area,and the results show that the multi-scale model can provide rapid simulation and accurate decision-making for flood simulation analysis in Taihu Lake area of Jiangsu Province,and strongly support flood scheduling in Taihu Lake area of Jiangsu Province.
