Analysis of Atmospheric Environmental Changes During the ＂Eleventh Five-year Plan＂ Period in Jiyuan
Abstract：Based on the monitoring data of atmospheric environmental quality of Jiyuan during the ＂eleventh five-year plan＂ period, firstly analyzed annual and seasonal average concentrations of the main atmospheric pollutant in Jiyuan, then the trends of atmospheric pollution levels were analyzed by using integrated pollution index and Spearman rank correlation coefficient method, and analyzed the comprehensive pollution index of atmospheric pollutants between end of the ＂ eleventh five-year plan＂ period and ＂tenth five-year plan＂ period. The results show that, the atmospheric environmental quality of Jiyuan was generally stable and improved, but there were also a degree of pollution, especially the pollution levels in winter significantly higher than other seasons, SO2 was still the primary pollutant. Finally, proposed the countermeasures and suggestions for further improving the quality of atmospheric environment.
