And the relevant data of environmental monitoring in Liaoning Province. The regression curve with the best fitting degree was obtained, and the data of the whole country and Liaoning Province in 2015 were verified. The relationship between environmental pollution indicators and economic growth (per capita GDP) in Liaoning Province and the whole country was analyzed and forecasted.The results show that, both the Liaoning Province and the whole country, with the increase in per capita GDP, the per capita wastewater discharge and smoke dust emissions increase, and the per capita chemical oxygen demand emissions and sulfur dioxide emissions decrease.
