| 摘 要： | 为更全面、精确地评价环境空气质量,对基础数据进行考察,提出了采用统计学指标反映时域内污染物浓度的方法。通过相关物理意义的分析,采用均值、方差、标准差、峰度和偏度为参考指标,建立了污染物浓度统计总体的评价体系,并依据标准限值做统一无量纲化处理。以2008年温州市黎明路空气站监测数据为例,研究发现:统计学指标结果可较好地反映时域内的污染状况,并在污染因子间与污染因子内部的对比分析中具有较高的准确性和科学性。

| Abstract: | In order to evaluate air quality comprehensively and precisely,basis data have been investigated,and statistical indications have been presented to reflect pollutants concentration in time domain.Analyzing the related physical meaning,mean,variance,standard deviation,kurtosis and skewness have been utilized to establish overall evaluation system for pollutants concentration statistics.In addition,unified dimensionless treatments have been carried out based on standard limits.Taking the case of Wenzhou Limin... |
