摘要：在測噪聲的過程中，通常需要獲得監(jiān)測點(diǎn)的空間分布特征以便對(duì)噪聲污染在空氣中的擴(kuò)散進(jìn)行準(zhǔn)確的監(jiān)測。傳統(tǒng)的方法難以達(dá)到準(zhǔn)確、直觀的效果，而GIS技術(shù)能夠解決上述問題。以南京曉莊學(xué)院為例，制定了基于GIS技術(shù)的區(qū)域噪聲環(huán)境影響評(píng)價(jià)方案，該方案利用GIS的空間分析功能，在XX學(xué)院內(nèi)布好相應(yīng)的監(jiān)測點(diǎn)位，通過測量的結(jié)果來了解學(xué)校的噪聲污染狀況以及哪個(gè)監(jiān)測點(diǎn)位的噪聲環(huán)境影響最嚴(yán)重。結(jié)果表明：XX學(xué)院晝間等效連續(xù)Ａ聲級(jí)（Ｌｅｑ）平均值為55.13dB，校園環(huán)境對(duì)教學(xué)沒有太大影響，夜間為47.71dB，高于國家標(biāo)準(zhǔn)，主要受校園周邊道路的交通噪聲和服務(wù)區(qū)的噪聲影響。

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.
