摘    要:
传统的空气质量评价的参数化组合算子模型不具有可比性和普适性。在适当设定指标参照值cj0和指标规范变换式基础上,提出了一个对多项空气指标的规范值xj都适用的空气质量评价的参数化多元组合算子模型;采用混合蛙跳算法对模型中的参数进行优化,得到优化后对多项空气指标皆普遍适用的空气质量评价的参数化多元组合算子模型。该模型被应用于多个不同地区的不同组合指标的空气质量评价,其评价结果与用其它多种方法的评价结果相一致。结果表明:用指标规范值表示的参数化多元组合算子模型为空气质量评价提供了一种计算简便和普适通用的新方法。

关 键 词:环境科学  空气质量评价  参数化组合算子  普适模型  混合蛙跳算法

Abstract:
Traditional parameterized combination operator model for air quality evaluation lacks of universality and comparison.A universal parameterized combinatorial operator model suited to air quality evaluation of the normalized values of multi-index was proposed on the basis of setting reference values and normalized conversion form of indexes.Meanwhile,the parameter involving in the model was also optimized by using Shuffled Frog Leaping Algorithm(SFLA).The optimized universal combination operator model is suitable to air quality evaluation for arbitrary multi-index.Furthermore,the model was applied to the practical air quality evaluation for different combinatorial indexes in various districts,with the evaluation results coincident with that obtained from other evaluation methods and also in correspondence with actual conditions.Results show that the model is a new simple and practical method for air quality evaluation.
Keywords:environmental science  air quality evaluation  parameterized combination operator  universal model  shuffled frog leaping algorithm(SFLA)
