摘要
城市化进程加快,城市面临诸多复杂问题,迫切需要借助数字化手段实现科学化、精细化和智能化的城市治理。仿真推演作为数字孪生城市的核心能力,可基于虚拟模型对城市运行状态进行模拟、预测和推演,为科学决策提供支撑。但城市多维数据的庞大规模、种类繁多、模型复杂以及可视化困难,给仿真推演带来新挑战。本文提出了面向城市治理的多维仿真推演总体设计,设计了包含建模、仿真引擎、可视化、交互控制、分析评估和集成互操作等子系统的仿真推演平台框架。重点探讨了城市系统多维建模、跨尺度模型协同仿真、面向推演的可视化交互和基于智能优化的策略生成等关键技术。最后介绍了一个城市多维数据仿真推演平台的架构设计和工作流程,以及在城市雨洪管理等场景的应用案例。该仿真推演体系能够实现对城市多维数据的高效获取、模型构建、模拟运行、结果分析和策略优化,助力城市治理从定性向定量化、科学化转变。
The accelerated urbanization process has led to many complex problems in modern cities,and urban governance urgently needs to leverage digital means to achieve scientific,refined,and intelligent management.As a core capability of the digital twin city,simulation and analysis can simulate,predict,and extrapolate the operational status of the city based on virtual models,providing support for scientific decision-making.However,the large scale,diverse types,complex models,and visualization difficulties of urban multi-dimensional data pose new challenges for simulation and analysis.To address these challenges,this paper proposes an overall design for multi-dimensional simulation and analysis oriented towards urban governance.It designs a simulation and analysis platform framework consisting of subsystems such as modeling,simulation engine,visualization,interactive control,analysis and evaluation,and integrated interoperability.It then focuses on discussing key technologies such as multi-dimensional modeling of urban systems,collaborative simulation of cross-scale models,visualization and interactive analysis oriented towards simulation,and strategy generation based on intelligent optimization.Finally,it introduces the architectural design and workflow of a urban multi-dimensional data simulation and analysis platform,as well as application cases in urban stormwater management.This simulation and analysis system can achieve efficient acquisition of urban multi-dimensional data,model construction,simulation operation,result analysis,and strategy optimization,helping to transform urban governance from qualitative to quantitative and scientific,and improve the modernization level of urban governance.
