Embodiment Construction

[0016] The present invention will be further described below in conjunction with the description of the drawings and specific embodiments.

[0017] In view of the rapid urban construction in my country and the requirement that urban planning should scientifically control the spread of noise, the specific application of noise map technology in my country needs to consider the timely response to noise sources. The noise map drawing method carried out every 5 years through a large number of censuses in foreign countries cannot meet the rapid urbanization development in my country at the present stage. The key to this invention is to develop an automatic noise map drawing technology that can be updated in a relatively short period of time. This technology mainly includes three technical platforms: 1) establishing an automatic noise monitoring network covering urban areas; 2) drawing background noise maps for urban areas; 3) updating noise maps. The research and development of this...

Abstract

The present invention provides a noise map drawing method applied to urban planning and construction project environmental impact assessment. The method comprises the steps of: S1, establishing a noise automatic monitoring network to perform automatic monitoring of noise, wherein the noise automatic monitoring network performs statistics automatic monitoring statistic data of the noise once at intervals; S2, comparing the current automatic monitoring statistic data with a background noise map, if the different therebetween does not exceed a threshold value, finishing the steps, or else, entering the next step; and S3, updating and drawing a noise map according to the current automatic monitoring statistic data, and applying the noise map to the urban planning and construction project environmental impact assessment. The noise map drawing method can update the noise map in short time to combine the noise automatic monitoring and the noise map technology to meet the noise environmental evaluation requirement of urban planning and projection construction in the period of rapid development in our country.

Description

technical field [0001] The invention relates to a noise map drawing method, in particular to a noise map drawing method applied to urban planning and environmental impact assessment of construction projects. Background technique [0002] Noise map technology uses computer simulation to perform model calculations on noise source data, geospatial information data, road, rail transit data, etc., and then forms a color map technology that can reflect the noise environment. This technology converts invisible noise into a visible map form by combining acoustic simulation models with geospatial graphics rendering software to show the distribution of noise pollution in the regional environment. Thus, the problem of inaccurate and inaccurate reflection of noise pollution caused by traditional on-site measurement and formula calculation has been changed. [0003] Currently, there are two types of noise monitoring technologies: manual monitoring and automatic monitoring. Manual monit...
