Abstract: In the light of the statistical data of economic (per capita GDP) increasement and the amount of discharged industrial “three wastes” during 1986~2003 in Wuhan city, the interrelations between per capita GDP and the amount of discharged pollutants were analyzed and the quadratic model were also established by dint of the SPSS and EXCEL software. The result shows that the amount of discharged pollutants (such as industrial waste water, Cr+6 in industrial waste water, SO2 in industrial exhaust gas, industrial dust, industrial solid waste and so on) in Wuhan city, except the generation and discharge amount of industrial solid waste are still in a dilemma region, have got through or are getting through the EKC curve turning point, which indicates that the environment condition is becaming better in Wuhan city. According to the result, the feasibility ironing out the tend of EKC curve of the discharge amount of industrial “three wastes” pollutant were analyzed before the environment has not been destroyed and the resource has not been exhausted completely.

Key words: industrial “Three wastes”, per capita GDP, the quadratic model, EKC, Wuhan city
