摘　　要：介绍了田湾核电工程复杂地形厂址地区山体对流动和扩散影响的风洞模拟实验研究方法和结果。该实验以厂址为中心应用 X型热线探头探测了不同风向下的平均流和湍流结构。用乙烯示踪扩散实验法研究复杂地形污染物扩散的规律。根据实验结果建立了估算复杂地形扩散参数的经验方法 ,还给出了一个估算复杂地形大气扩散的模式 ,该模式预测结果与现场实验数据相吻合。A wind tunnel study on the effects of hills on the flow and diffusion in Tianwan Nuclear Power Plant site area was described in detail. In the experiment, the mean flow and turbulent structure with different model orientation were investigated by using a X configuration hot wire probe. The concentration distribution and diffusion characteristics were investigated through the ethylene tracer measurements. An empirical method is put forward to estimate diffusion parameters in complex terrain in the light of the results of tests. Moreover, a numerical model is developed to simulate atmospheric diffusion in complex terrain. The predicted concentrations from this model are consistent with the field experimental data.$$$$
