摘　　要：风速对某些运动项目影响较大,因此当体育场内风场复杂时,其场内的风环境不容忽视。本文采用SSTk-ω湍流物理模型,对闽南某体育场内的风环境进行数值模拟,得出了场内跑道区域行人高度处的风速比,并对体育场内的风环境进行了预测和评估,提出了改善风环境的一些方法。The velocity of wind has a greater impact on some sports, so the on--site wind environment can not be ignored if the wind field in the stadium is complicated. The SSTk--ω turbulence physics model was introduced in the numerical simulation of the wind environment in the stadium of minnan. As a result, the wind speed ratio at the pedestrian height above the raceway area was educed and the prediction and evaluation of the wind environment in the stadium were put forward, what＇s more, a few ways were proposed to improve the wind environment.
