摘　　要：提出一种适用于大区域噪声评价的模型——NEM模型,该模型综合考虑暴露人群和声环境功能区差异,并根据城市声环境质量标准及噪声对人体健康的影响程度进行了分级表征。文章运用该模型对广州市噪声状况进行评价,同时将评价结果分别与NPI法和NII法的评价结果进行对比。对比结果表明:NEM模型用于大区域环境噪声评价科学合理,结论可靠。The paper proposed a noise evaluation model,NEM,aiming at large-scale area. The discrepancy caused by the noise in exposed crowds and varieties of noise environmental function areas was considered comprehensively and was made a hierarchical representation according to environmental quality standard for noise in city and the impact on people's health by noise in the NEM model. Furthermore,in case study,an evaluation of Guangzhou's noise condition was presented using NEM model. Contrasted with NPI method and NII method,the comparison of evaluation results indicated that to evaluate noise in environmental large-scale area the NEM model is scientific and reasonable,and reliable to get the conclusion.
