临夏市道路交通噪声环境质量二级模糊综合评价

Environmental Quality of Road Traffic Noise in Linxia City Evaluated by Secondary Fuzzy Comprehensive Evaluation

为了全面反映临夏市道路交通噪声污染现状,采用二级模糊层次综合评价模型对临夏市9条主要交通道路31个监测点的监测值进行分析,结果表明:临夏市道路交通噪声整体属于较清洁状态,平均值为69.4dB(A);9条道路中城东一路属于清洁状态,平均值为66.3dB(A);前沿河路以及团结路属于轻污染状态,平均值分别为74.8dB(A)、75.1dB(A);其他道路均属于较清洁状态。其结论符合临夏市的实际情况,不仅实现了临夏市道路交通噪声污染现状的定量评价,而且分析了小范围路段对临夏市噪声环境质量的影响。

In order to fully reflect the pollution status of road traffic noise in Linxia City, observations from 31 monitoring stations located on nine main roads were analyzed using the secondary fuzzy comprehensive evaluation model with the analytic hierarchy process. The results showed that the overall status of the traffic noise in Linxia City was relatively clean with an average of 69.4 dB（A）. Chengdongyi Road was in a clean status among the nine roads with an average of 66.3 dB（A） while the others were in a relative clean status except that Qianyanhe Road and Tuanjie Road were in a light polluted status with an average of 74.8 dB（A） and 75.1dB（A）, respectively; The conclusion was in conformity with the current situation of Linxia City. Furthermore, this study not only evaluated the current status of the road traffic noise pollution in Linxia City, but also analyzed the impact of noise of small sections on the environmental quality in Linxia City. f
