摘要
Relationships between environmental pollution and economic development in Binzhou during 2001- 2013 were studied through an Environmental Kuznets Curve( EKC). The results showed that with the increase of GDP per capita,the emissions of industrial wastewater,COD and ammonia nitrogen in Binzhou City increased at first and then decreased during 2001- 2013,showing inverted-U-shaped curves where turning points appeared in the middle; the emission of domestic sewage showed an upward trend,and a turning point would not appear in a short term; the emissions of domestic COD and ammonia nitrogen dropped firstly and then rose gradually,showing U-shaped curves,and they would not decrease in a short time. The turning points of industrial wastewater,COD and ammonia were at( 4. 29,14 550),( 2. 46,44 803) and( 2. 27,2 708) respectively; domestic sewage had no turning point,and domestic COD and ammonia nitrogen would not reach the turning points in a short term.
