城市区域环境噪声标准

GIS在城市区域环境噪声标准适用区划分中的应用县级城市（镇）环境噪声标准适用区域划分方法和程序探讨

Method and procedure of district division for environmental noise standard being suitable to city at county level

认为环境影响评价的噪声适用标准应以排放标准为主，并提出修订城市区域环境噪声标准和铁路环境噪声标准时，应充分注意铁路的类型及其噪声的特点，提高标准的科学性和可行性。

When the noise standard for city regional environment and the noise standard for railway environment being revised , the type of railway and its noise character should be sufficiently noticed , so to improve the scientific character and feasibility of the standard .

为有效地控制城市噪声污染的程度和范围，便于城市环境噪声管理和促进噪声源治理，城市区域环境噪声标准适用区划分（以下简称“噪声区划”）势在必行。

In order to effectively control the degree and scope of city noise pollution , strengthen city environmental noise management and promote noise control , city environmental noise division is necessary .
