摘要： 近年来,夏季炎热的气候和愈来愈强的热岛效应使城市饱受因挠,而城市设计策略中缺乏有效的生态规划方法来解决目前存在的问题,城市对炎热气候的适应性不足。论文在利用CFD(计算流体动力学)技术进行实例模拟分析的基础上,重点介绍了一种在城市尺度进行节能设计的新方法:在城市中建立多种形式的通风道,提高城市的通风和排热能力,以达到利用自然资源和有效的规划方式降低夏季城市“热岛”温度、节约能源的目的。文中详细论述了通风道的可行性和必要性、营建方式、注意原则等问题,并进行了一系列的计算机风场模拟研究。

Abstract: Wind,floating climate factor in nature,is one of the important components of urban eco-systems.Wind environment can promote communication between hot and cool air and be a media between metropolitan and ecological area.It can also enhance the ability of cities to suit hot climate.Basing on simulation CFD,this paper focused on a new way of the saving-energy design in urban planning.This way intended to build a few kinds of urban ventilation channels.The methods for increasing area's quality of ventilation and reaching the aim of lowing down the temperature of hot-island in summer and saving energy by using natural resources and efficient planning is introduced.This paper also discusses the issues of ventilation channels' feasibility,necessity,building types and so on.Then it displays a series of computer-aided research in wind field.

Key words: climate regulation, energy saving, skill of computational fluid dynamics, ventilation channel
