Application On The Noise Mapping In Macau’s Noise Pollution Provention And Control Planning

the noise pollution is one of very prominent environmental problem in the modern city, but as a result of noise pollution relatively pollution has not continuity, dispersion, concealment, relative to the atmosphere, water environmental problems such as speaking, whether pollution mechanism, control measures are much more weak. So around the city noise pollution of the environment problem, the use of modern noise map information technology, guide noise pollution prevention and control planning, has a very important significance.This paper discusses in detail the noise environment management and noise map based on the study of home and abroad, through the typical region of the Macao special administrative region, the prevention and control of noise pollution planning this case, this paper expounds in detail the the following contents:Through the Macao noise census and years noise measured data show that the Macao regions were all influenced by a certain degree of noise pollution, night and day, sound level difference is small, and of the macau peninsula for a high population density, business activity is frequent, traffic flow is big, the contaminated the highest degree, Taipa and road Taipa new town near the acoustic environmental quality, ratio of the macau peninsula is slightly better, leave insular road link continuously then because of its social and economic development level is low, population density, social activities and road traffic are better than other areas in the lower level, noise pollution in the district domain minimum. The basic and regional social and economic development level consistent.The selected GaoShiDe area, London street area of two typical regions, by the use of GIS technology and acoustic simulation technology, with the aid of ArcGIS software and acoustic Cadna/A software, eventually making out two selected area noise map. Noise map to plane sound field, stereo field and equipped with geographic information released form.According to the noise map application characteristics, based on all kinds of noise noise reduction measures detailed planning, and in the space layout in detail, the space layout optimization is aimed at road Taipa new town and new reclamation area. First, the planning should avoid traffic trunk road in residential neighborhoods across; Residential land should be organized form is given priority to, and avoid and industrial land and the entertainment industry land facies confounding, reasonable division of different function of the land, and for old town mingle in processing factory should also gradually withdraw; In the traffic trunk road side of the building should take "peripheral type" decorate, unfavorable use "determinant" decorate, frontage first building in the parking lot, business center, and other ability noise architecture is given priority to, can effectively reduce the noise influence in row buildings; Built "leapfrog" layout, form the bottom of cross road noise building, top for residential space layout, in order to achieve can use limited land space, and can reduce the traffic noise on the influence of the house.
