摘　　要：建筑风环境对建筑能耗及气态污染物扩散起到决定性作用.为了解浙南地区小尺度范围的地形变化对民用建筑风环境的影响,本文利用STAR-CCM+软件对温州地区几个工程项目的再现域范围、盛行风向和局部风向、风速、风压等方面进行了数值模拟分析.结论如下:附近的山体、坡地、谷地等小尺度地形变化对场地风环境的影响超过地区盛行风.风环境模拟应再现可能影响目标区域的地形变化.研究结论可为浙南地区民用建筑选址提供参考.The main terrain of South Zhejiang is mountain and hilly,therefore the building wind environment in South Zhejiang is more complex than common plain city.According to numerical simulation of STAR-CCM+,taking several engineering projects in Wenzhou as examples,the influence of small-scale terrain changes on civil building wind environment in South Zhejiang is studied in this thesis.Discussion will be made in aspects of simulation reproduction area,prevailing wind direction and local wind direction,wind velocity and wind pressure.Conclusion is as follows:the influence of nearby small-scale terrain changes,such as hills,slopes and valleys,on wind environment of a certain site exceeds the prevailing winds;wind environment simulation should reproduce the terrain changes that may influence over the target area;the impact of small-scale terrain changes on wind environment should be fully considered when siting in South Zhejiang.
