灰色聚类评价在经济区大气环境质量评价中的应用

Application of Grey Clustering Method for Atmospheric Environmental Quality Assessment in Shenyang Economic Zone

利用灰色系统的灰色聚类评价方法,以沈阳经济区的沈阳、鞍山、辽阳、本溪、抚顺为聚类对象,以PM10、SO2、NO2三个评价因子为聚类指标,国家空气质量标准的一级、二级、三级标准三个灰类为聚类灰数,对2008年沈阳经济区大气环境质量进行了综合评价。结果表明:在沈阳经济区五个城市中污染程度辽阳最重,然后为沈阳,抚顺,鞍山,本溪最轻。利用灰色系统的灰色聚类评判方法,对沈阳经济区大气环境质量进行了综合评价,结果与实际情况相符。

based on data of 5 city monitoring stations in 2008,atmospheric environmental quality of Shenyang Economic Zone were evaluated by using grey clustering method with Shenyang,Anshan,Liaoyang,Fushun,Benxi as clustering objects,PM10、SO2、NO2 as clustering index and national air quality standard ⅠⅡⅢ as grey parameters . The result showed that Liaoyang was the heaviest polluted city in Shenyang Economic Zone. Air quality assessment of Shenyang Economic Zone by using grey clustering method had the same result as reality.
