摘　　要：目前中小比例尺模型研究涉及各类复杂地形,但对整个城市还很鲜见。论文对广州市核心建成区立体形态模型在东南风和西北风风向进行风洞模拟,从回流、加速和减速三方面探讨城市的风场特征。实验结果表明,回流出现在城市背风坡、高层建筑物后及由高层建筑物围合的盆地地形中。加速区分布于城市外围、城市迎风坡以及峡谷地形中,减速区发生在背风坡及回流强度较大的区域。依据城市建筑立体形态对风场的影响规律,对城市在规划等方面提出优化对策,从而改善城市风场环境。The present study of small and medium scale model involves various types of complex terrain, but to the city is still very rare. In the core building area of Guangzhou, through the wind tunnel simulation of the three-dimensional shape model in the southeast and northwest wind,this paper will discuss characteristics of wind field in the city from three aspects of backflow, acceleration and deceleration. The experimental results show that the backflow appears in the leeward slope of the city, high-rise buildings and basins surrounded by the high-rise buildings, the accelerating region distributes in tbe outskirts and windward slopes of the city as well as the canyon terrains. deceleration zone occurs in the leeward slopes and areas with larger reflux strength. According to the influence of the three dimensional shape of the city building on tbe wind field, this paper will propose the optimization measures in the city planning in order to improve the city wind environment.
