摘要 为探讨城市以较少网格监测点获得较科学的声环境信息,分析区域环境噪声监测点的优化问题,减少每年监测带来的巨大工作量。在借鉴国内噪声监测优化布点研究成果的基础上,结合环境噪声污染特征,以福建省某城市为例,运用物元分析法和熵权法确定最优测点数,把该市区域环境噪声普查的152个监测点位优化为12个。将此方法与统计分析方法作比较,经验证,两种方法监测的等效声级和标准差平均值均<2d B(A)。 In order to get more scientific acoustic environmental information with less monitoring sites, the optimi- zation of noise monitoring sites of the urban area was analyzed. Based on the current results of optimizing the noise monitoring sites combining with the characteristics of noise pollution in China, Fuqing city was studied as a case. The 152 monitoring points were optimized to 12 using the substance element analysis and coefficient of entropy. Comparing the method with the statistical analysis method, the equivalent sound level and standard deviation of the two methods are all less 2 dB (A). Therefore, there was no significant difference between these two methods.
