摘要
本文在分析多种环境质量评价数学模式的基础上,对加权均值数学模式的"权值"给法进行了研究,采用专家询问方式,给出各种污染元素的"权值",提出一种简易可行的大气质量评价数学模式.用此种方法,对哈尔滨市城区1984年度大气污染进行了评价,得出大气污染状况分布,符合当时的实际污染情况.
Based on the analysis of some mathematical model about evaluation of en- vironmental quality,we investigated the method of weighted values of weig- hted mean model in the paper,by inquiring suggestions from specialists we gave the weighted values of various air polluting elements and gave another mathematical model for evaluation of air quality.By using this method we e- valuated the air pollution in the urban area of Harbin.and obtained its dis- tribution of air pollution(1984).The result meets the actual situation of air pollution at that time.
