近年来为解决城市交通拥挤问题,我国一些大中城市,如沈阳、大连、长春、哈尔滨、重庆、杭州等,正在规划和筹建轻轨交通,但轻轨交通引起的噪声污染程度如何,不但是社会上十分关心的问题,也是轻轨建设需要解决的问题.由于我国尚无建成的轻轨交通系统以资借鉴,无法直接取得实际噪声数据,给预测带来一定困难.为此,本文根据作者在沈阳轻轨一期工程环境影响评价中所作的噪声预测,就预测方法问题作一探讨,以求得同行的批评和指正.
In recent years, to solve the problem of urban traffic congestion, some large and medium-sized cities in China, such as Shenyang, Dalian, Changchun, Harbin, Chongqing and Hangzhou, are planning and preparing for the light rail transit. However, the degree of noise pollution caused by light rail transit is not only the social The problems that are of great concern are also the problems to be solved in light rail construction.As there is no light rail transit system built in our country, it can not directly obtain the actual noise data, which brings certain difficulties to the forecasting.Therefore, The noise prediction made in the environmental impact assessment of the project is discussed on the prediction methods to obtain the criticism and correction of the counterparts.
