基于GIS技术的遵义市主城区声环境质量现状及空间分布特征分析

An Analysis of the Situation and spatial Distribution Characteristics of Acoustic Environment Quality in the Urban Built-up Area of Zunyi

随着城市化进程的加快,城市噪音污染也与日俱增。作者通过实地监测遵义市主城区的区域、道路交通和功能区噪声声级,基于GIS技术分析声环境质量现状及空间分布特征。结果显示:(1)区域噪声声级均值为52.1 dB(A),区域声环境质量总体表现为较好水平,新蒲新区和播州区声环境质量优于汇川区和红花岗区;(2)道路交通声环境质量等级总体达标,监测点达标率为74.12%,汇川区和红花岗区交界处道路交通声环境质量较差;(3)4类功能区昼间和夜间的噪声声级低于其相应标准限值1~2个等级,功能区声环境质量总体水平较好。研究结果可为遵义市城市环境管理部门提供科学的数据支持和技术支撑。

The problem of urban noise pollution would become more and more serious with the acceleration of urbanization in Zunyi city.The situation and spatial distribution characteristics of acoustic environment quality in the urban built-up area of Zunyi city was analyzed by means of GIS technology,which through in-situ monitoring the noise sound level in sub-district,arterial traffic and functional district.Results showed as follows.1)The overall of acoustic environment quality in sub-district was better,which had a mean value of 52.1 decibel noise sound level.And the acoustic environment quality in Xinpu new district and Bozhou district were better than that of in Huichuan district and Honghuagang district.2)The acoustic environment quality level in arterial traffic reached the national standard in the mass,and the rate of monitoring points came up to 74.12%.3)The overall level of acoustic environment quality in the four functional districts were suitable,which was result of the actual noise sound level downgrading of 1~2 level than the national standard.
