摘要
西安市部分规模以上工业增加值同大气污染物的关系研究采用双变量相关性进行分析。文中选用西安市汽车制造业增加值,电力、热力生产和供应业增加值,燃气生产和供应业增加值以及有色金属冶炼和压延加工业增加值和同时段的二氧化硫、二氧化氮、PM10以及PM2.5浓度值8组数据作为研究对象,进行分析后得出结果,即二氧化硫、PM10和PM2.5三类大气污染物浓度值与电力、热力生产和供应业增加值相关关系较显著,与燃气生产和供应业增加值相关关系显著,与其它两项增加值相关关系不明显或不具有相关性;二氧化氮浓度值与燃气生产和供应业增加值相关关系较显著,与其它三项增加值相关关系不明显或不具有相关性。
The relationship between the industrial added value ofsome above-scale industries and the air pollutants in Xi＇an is an-alyzed by the bivariate correlation. The concentration values ofsuch three kinds of air pollutants as sulfur dioxide, PM10 andPM2.5 have a relatively significant dependence relation with theadded value of electricity, heat production and supply industries,have a significant dependence relation with the added value ofgas production and supply industry, and have an insignificant orno relation with the added values of other two items; the concen-tration value of nitrogen dioxide hasa significant independencerelation with the added value of gas production and supply in-dustry, and has an insignificant or no relation with the added val-ues of other three items.
