摘要
选取2007—2012年的PM_(10)年均浓度变化和粗钢产量等7项主要经济指标,运用灰色关联分析法计算关联度系数,对比分析长三角地区及其三省一市的关联度系数,找出地区不同省市的主要污染原因,为大气污染制定控制措施提供有效的决策参考。
By choosing seven main economic indicators such as annual average concentration change of PM_（10）,crude steel output and so on,by using grey correlation analysis method to calculate correlation coefficient,this paper comparatively analyzes the correlation coefficients of the Yangtze River delta region and three provinces and a municipality,and tries to find main pollution causes in different provinces and municipality in this region in order to provide effective decision-making reference for control measures for atmospheric pollution.
