大连市环境库兹涅茨曲线分析

利用大连市2006—2015年经济发展与环境质量统计数据,拟合出大连市环境库兹涅茨曲线(EKC)并分析了相关影响因素。结果表明,随着人均GDP增加,SO_2浓度、NO_2浓度、近岸海域水质劣于二类站位比例呈倒"U"型曲线,地表水劣于Ⅲ类水质断面比例呈线性下降,PM_(10)浓度呈正"U"型曲线,4类区噪声超标率呈"N"型曲线。

Analysis on the Environmental Kuznets Curve of Dalian

Based on the statistical data of economic development and environmental quality of Dalian from 2006 to 2015, the EKC curve of Dalian is fitted and the relevant influencing factors are analyzed. The results show that with the increase of GDP per capita, SO2 concentration, NO2 concentration and the station proportion of water quality of nearshore sea area inferior to class II shows an inverted "U" curve; the proportion of surface water inferior to class III water quality shows a linear decline;the concentration of M10 showed a "U" curve; the rate of noise exceeding the fourth standard class shows a "N" curve.
