基于数字化技术的城市热岛效应研究

Research of Urban Heat-island Effect Based on Digital Technology

数字化模拟是一种快速、高效、经济的研究手段,与传统研究方法相比,它不但节省了大量的人力和物力,还能完成传统方法所无法完成的实验,填补以往研究方法的空白区域,在此次研究中,通过Ecotect软件与CFD软件的结合运用,对上海市主城区七月份午间典型工况下的城市热环境进行了仿真模拟,使我们对可以对城市"热岛效应"的分布、成因以及与城市热环境密切相关的风速、温度、太阳辐射、大气压等一系列气候因素有更深的了解。

Digital simulation is a fast, effective and economical research method. Compared to traditional research method, it can not only save a lot of manpower and material resources but also can fill the gap of traditional research, In this research, we simulate Shanghai＇s thermal environment in July under typical afternoon working conditions by the comprehensive application of Ecotect software and CFD sottware. The research enhances our understanding of the distribution and cause of ＂Urban Heat Island Effect＂, and the climatic factors （wind velocity, temperature, solar radiation, atmosphere pressure, etc） that are closely related to urban therma environment.
