环境空气质量评价的普适指数公式

An universal index formula suited to environmental air quality assessment

在适当设定空气污染物的基准值和用相对于基准值的空气污染物的“相对”值情况下 ,采用 S型曲线表示空气污染物对环境空气质量的危害程度 ,并应用遗传算法优化公式中的参数 ,得出了一个对多种空气污染物通用的环境空气质量评价的普适指数公式。借助于折衷型激励功效函数将单项污染物分指数加权为综合指数。该公式形式简单 ,容量计算、评价结果精度较高 。

Based on the hypothesis of base values and relative values of air pollutants, the harm extent of air pollutants for envieronmental air quality was represented with S curve. An universal index formula of environmental air quality assessment suited to multi pollutant was presented for the optimum of parameters using genetic algorithms. The comprehensive index of environmental air quality assessment can be calculated in the aid of the compromise active function weighting for each index. The formula is simple and easy for calculation and the results of assessment shows high precision and comparison.
