摘　　要：村落民居风环境的合理分布对村落的后期建设具有重要的意义。本文建立了村落建筑风环境分布模拟模型,进行了数值模拟研究。研究结果表明:在无附属建筑遮挡的情况下建筑迎风面风压值最大;受到建筑阻挡的影响,风沿建筑迎风面上升,在建筑上部一定距离处,流线汇集,在建筑背风面风速迅速降低。Reasonable wind environment distribution of village residential plays a significant role in the latter building part of the village.In this paper,the wind environment simulation model of village was established,and numerical simulations were studied by the CFD（computational fluid dynamics）commercial soft.The results show that the largest construction windward wind pressure of building is attained with the absence of the subsidiary block and with the impact of building,the wind along the windward is ascending,flow lines together in the certain distance upper part of the building,and wind velocity becomes lower quickly in the leeward side of the construction.
