水文模型在湿地景观规划设计中的应用研究

Application of Hydrological Model in Wetland Planning and Design

利用水文模型能概化复杂的水文现象与水文过程,输出可视化结果。水文模型的应用能够促进湿地景观规划设计由经验决断向客观可度量的循证设计转变,为景观规划设计提供科学的参考依据。文中阐述了湿地景观规划设计中模型应用的发展,对比MIKE21、WASP、EFDC、Delft3D和SWMM 5个可用于湿地景观规划设计的水文模型,概述各模型在景观规划设计领域的应用现状,提出基于临岸流速、水深分布、水质和流场模拟结果的湿地景观规划设计策略,总结水文模型在湿地景观规划设计中的研究前景和方向,可为湿地景观的设计与营造提供借鉴与指导。

Complex hydrological phenomena and processes can be generalized and visualized by hydrological model.The application of hydrological models can promote the transformation of the wetland landscape planning and design from empirical determination to evidence-based objective and measurable design,which provides a scientific reference for landscape planning and design.This paper describes the development of model application in wetland landscape planning and design,compares five hydrological models of MIKE21,WASP,EFDC,Delft3D and SWMM that can be used in wetland landscape planning and design,and outlines the current state of application of each model in the field of landscape planning and design.It proposes a strategy for wetland landscape planning and design based on the simulation results of coastal flow velocity,water depth distribution,water quality and flow field,and concludes the research prospects and directions of applying hydrological models in wetland landscape planning and design.This study would provide references and guidance for the design and creation of wetland landscapes.
