用灰色聚类关联分析法对矿业城市大气环境灾害的评价

Application of Grey Cluster Relation Analysis Method to Assess the Air Environmental Quality in Mining City

将灰色聚类关联分析法应用于矿业城市大气环境灾害的评价中,介绍了评价方法和步骤,并用该方法对阜新市1996至2000年连续5年的大气质量监测结果进行评价,根据关联度判断出1996和1997年的大气环境质量为第Ⅲ级,1998—2000年为第Ⅱ级,大气环境质量的优劣次序为:1998>1999>2000>1997>1996.根据权重分析出影响矿业城市阜新市大气污染的主要污染物是TSP,为改善大气质量,减弱大气环境灾害提供了参考依据.

The grey cluster relation analysis method is applied to air environmental quality assessment to introduce its method and procedure. This method is used to evaluate Fuxin City air quality based on monitoring results of 1996--2000. The atmospheric environment quality of 1996 and 1997 is classified to Ⅲ while 1998--2000 is Ⅱ judged by correlation degree. The order of environmental disaster priorities is 1998〉1999 〉2000〉1997〉1996 and it matches the actual pollution level. The most serious factor contributed to pollution is TSP. These can provide references for air pollution control and weaken the atmospheric environment disaster.
