1996-2005年长治市空气环境质量及其影响因素分析

Analysis on the Air Environmental Quality and Influential Factors in the Air from 1996 to 2005 in Changzhi

对1996-2005年长治市大气环境监测资料进行了分析,结果表明长治市大气环境首要污染物为PM10,已超过国家三级标准,属典型煤烟型污染。长治市环境空气质量变化具有明显的时空变异特征。表现为夏秋季明显优于冬春季,城市周边地区优于城市中心区域。长治市环境空气质量超过国家二级标准的主要影响因素为机动车辆增加、面源污染严重、城市基础设施不完善、冬季气象条件不利和周边工业污染对城市的影响等诸方面。加强城市集中供热设施建设、控制扬尘污染是当前改善环境空气质量行之有效的控制措施。

Based on the 1996 to 2005 were analyzed. standard, showing that had clear time, space monitoring air environmental data, the air environmental quality in Changzhi from The results indicated that the main pollutant PMIO had exceeded the third class Changzhi changing belonged to a typical coal smoke pollution city. The air environmental quality characteristics, that was, the pollutant in winter and spring were more than that in summer and autumn,and that in the center of city were more than that around urban. The main factors causing environmental pollution included vehicles increase,diffuse pollution growth,imperfect urban basic facilities construction, disadvantageous effect of meteorological condition in winter and industrial pollution around et al. Some effective measures such as strengthening management, adopting concentrated heating, controlling wind blown, should be taken so as to improve the air environmental quality in Changzhi.
