中文摘要：

借助1990-2010年的统计数据，运用Eview软件，对西安市的经济增长与环境3大指标（工业废气、废水、固体废物）之间的关系进行拟合，对其关系是否符合环境库兹涅茨曲线（EKC）倒“U”型模型进行验证，并采用因素分析法，对影响环境质量的因子进行分析。结果表明：①西安市经济增长与环境3大指标之间的关系都不符合环境库兹涅茨曲线，经济增长与废气排放和废水排放的关系均满足倒“N”型曲线，与固体废物排放的关系基本满足“U”型曲线；②废气排放与废水排放开始显示下降趋势，而固体废物的排放依然在不断上升，并且没有发现达到最高点的迹象；③西安市的环境质量变化主要是由经济因素引起的。

Abstract： In this study, the statistical data of Xi＇an City during the period from 1990 to 2010 and the software of Eview were used to fit the relationships between economic growth and the three environmental indicators （industrial waste gas, waste water and solid wastes） in Xi＇an, validate whether the relationships were based on the environ- mental Kuznets curve （EKC）, and analyze the factors affecting the environmental quality with the factor analysis method. The results are as follows： ① All of the relationships between the economic growth and the three environ- mental indicators fell short of the environmental Kuznets curve, the relationships between the economic growth and the emission of waste gas and drainage of waste water met the inverted N curve, and the relationship between the e- conomic growth and the emission of solid wastes was based on U curve ; ② The emission of waste gas and drainage of waste water were in a decrease trend, but the emission of solid wastes was still in an increase trend, and the highest point was not reached yet ： ③ The change of environmental quality in Xi＇an was mainly caused by economic factors.
