环境质量报告书编写中的大气质量标准应用问题

Problems concerned with application of air quality standardsin the compilation of environmental quality statement

历年来,环境质量报告书的编写中,仅二氧化硫有年日均值国家标准,而其他污染物只有日均值标准,大气污染物污染指数和污染负荷的计算采用了不一致的均值标准,计算结果相对抬升了二氧化硫的污染程度,而相对降低了其他污染物的污染负荷。针对这种情况,本文提出了一种统计应用方法,旨在更好地应用国家大气环境质量标准对大气环境质量进行评价。

In the compilation environmental quality statement, the unconformable standards are used in the calculation of air pollotin indexes and pollution load parameters in the recent years. Because only the sulfr dioxide has the annualy natinonal standard while the other pollutants just have daily national sandards. Therefor the pollution indexes of these polloutants are not comparative, the polloutants indexes are not emphasized enough in relative with that of surfur dioxide. This paper provides a statistical method to solve the problems. By using this approach, the air quality standards can be applied to assess the ambient air quality condition smoothly.
