六安城区环境噪声污染综合评价

Comprehensive Evaluation of Environmental Noise Pollution in Urban Lu'an

利用环境监测部门区域环境噪声统计数据,对六安城区2000-2006年环境噪声源的构成进行分析,运用模糊数学方法对噪声环境质量进行了综合评价。研究表明,影响六安城区环境的主要噪声源为交通噪声和社会生活噪声,声环境质量总体来说较差,2000-2002年为中度污染,2003-2006年为轻度污染,污染状况呈现波动趋势。同时分析了模糊数学方法用于环境噪声评价的适宜性,验证结果科学可行。

Based on the statistics available from the Environment Monitoring Department, the paper has analyzed the composition of the environmental noise source in urban Lu＇an during 2000-2006. A comprehensive evaluation via the methods of fuzzy mathematics has been made on the noise environment. The study shows that the main noise source in urban Lu ＇an is traffic noise and everyday life noise. In general the quality of the environmental noise can be ranked as inferior,with a moderate degree from 2000 to 2002,and mild from 2003 to 2006. And the pollution presents a fluctuant trend. The paper has also tested the feasibility of the principles of fuzzy mathematics as employed in this case,and the result is that it is proved to be applicable to the evaluation of environmental noise quality.
