Dynamic evaluation of atmospheric environment quality in jining based on fuzzy comprehensive evaluation

This paper is based on the collection of atmospheric environment quality monitoring data and analysis of atmospheric environment quality evaluation method of Jining from 2002 to 2009. By aiming at coupling and complex dynamics of atmospheric environment, we apply fuzzy comprehensive evaluation method, and make an evaluation of atmospheric environment quality of Jining over the years. The results show that: the atmospheric environment quality of Jining has basically reached national Grade II standards. Aside from “slight pollution” in 2002 and 2006, it is “good” in the other years. Environmental quality remains generally stable. The contaminations are mainly PM
₁₀
and SO
₂
, then NO
₂
. With comparative analysis of annual trends, the result objectively reflects the situation of the atmospheric environment of Jining, and offers necessary theoretical basis to govern and improve urban environment.
