摘　　要：为解决城市环境噪声污染问题,基于城市噪声类型与分布的相关理论,研究得出车流量和车速是影响交通噪声的重要因素.通过分析不同噪声模型的差异,选择合适的噪声模型,利用南京市栖霞大道和玄武大道沿线几个区域安装的观测点实时监测的噪声数据,绘制测点区域的交通噪声地图.选取地图中一点,从全天来看,03∶00~04∶00时噪声大小处于全天最低值64~68 dB,19∶00时达到峰值76~80 dB.选取某一时刻,从整体噪声地图来看,噪声最大值为81 dB,最小值为71 dB.Theories about noise types and distribution are used to solve problems of urban noise pollution.The results show that traffic and speed are the large contributors to traffic noise.A model for studying traffic noise is chosen based on the investigations of different noise models.A map of traffic noise in measurement point area is drawn based on the real-time data of noise gathered from observation points installed in several areas along Qixia Avenue and Xuanwu Avenue in Nanjing.The data of the whole day indicates that the noise at three to four points is at the lowest value of 64~68 db,and the peak value at 19 points is 76~80 db.From the overall noise map,the maximum value of noise is 81 db and the minimum value is 71 db.
