摘要
以每个功能区面积占城市区域总面积的比例作为权系数 ,然后用加权平均法求出的城市区域环境噪声标准值来衡量整个城区的噪声水平 ,这样 ,在城市环境综合整治定量考核工作中对声环境状况评价真正做到定量化、标准化、针对城市的性质、规模、特征不同 ,也体现可比性。
Taking the total area of each functional area as weight coefficient,we can get the noise level of the whole city through the standard value of environmental noise of the whole city calculated by the way of weighted average.Then,the quantitative examination for evaluating the sound environment in the comprehensive improvement of urban environment can be quantification,standardization and comparability.
