摘　　要：校园建筑群的规划需要考虑人的舒适度。以浙江理工大学下沙校区中心建筑群为考察对象,对附近的行人高度风环境和空气污染物扩散情况进行了分析和评价。采用流体数值模拟技术CFD对各种影响因素进行了相应的计算,最后给出了评价和优化建议。分析表明:模拟情况与实地测量情况具有可比性;目标区域风场将产生较大混乱气流;不同的风速对于污染物的分布影响不大,污染物倾向于在建筑物的迎风面高压区聚集。Planning of campus buildings shall take human comfort into consideration.With investigation objects of central buildings in Zhejiang Sci-Tech University Xiasha Campus,this paper analyzes and evaluates the wind environment and air pollutant diffusion at pedestrian height nearby,calculates various influencing factors by fluid numerical simulation technology CFD,and finally gives recommendations for evaluation and optimization.Analysis shows that：the simulated conditions are comparable to field measurement conditions;wind field of target regions will generate great chaotic airflow;different wind velocities have little influence on the distribution of pollutants,and pollutants tend to gather in high-pressure regions at the windward side of buildings.
