摘要:在测噪声的过程中,通常需要获得监测点的空间分布特征以便对噪声污染在空气中的扩散进行准确的监测。传统的方法难以达到准确、直观的效果,而GIS技术能够解决上述问题。以南京晓庄学院为例,制定了基于GIS技术的区域噪声环境影响评价方案,该方案利用GIS的空间分析功能,在XX学院内布好相应的监测点位,通过测量的结果来了解学校的噪声污染状况以及哪个监测点位的噪声环境影响最严重。结果表明:XX学院昼间等效连续A声级(Leq)平均值为55.13dB,校园环境对教学没有太大影响,夜间为47.71dB,高于国家标准,主要受校园周边道路的交通噪声和服务区的噪声影响。

Abstract: In the measurement of noise in the process, often need to obtain the spatial distribution characteristics of monitoring points for noise pollution in the air diffusion for accurate monitoring. The traditional methods are difficult to achieve accurate, visual effects, and the GIS technology can solve the above problems. This paper taking Nanjing xiaozhuang university as an example, developed based on the GIS technique of regional noise environmental impact assessment scheme, the design using GIS spatial analysis function ,in Nanjing Xiao zhuang cloth within the corresponding monitoring point, by measuring the results to understand the school’s noise pollution status and which monitoring of noise environmental impact the most serious. The results showed that: Nanjing Xiao zhuang University circadian equivalent continuous A levels ( Leq) mean values for 55.13dB, The campus environment has little effect on Teaching,The night 47.71dB,Higher than the national standard,,Mainly affected by surrounding by the campus rode traffic noise and the noise impact of service area.
