Abstract:In order to reflect the changing trend of environmental quality objectively and provide a scientific basis for enviro nmental management decision-making,the air,acidic rain, surface water, and noise are analyzed by using Spearman rank correlation coefficient method based on monitoring data of enviro nmental qual-ity since the Tenth Five-Year Plan Period in Shaanxi Province. Results show that the environmental quality has being improved since the Tenth Five-Year Plan Period in Shaanxi Province. Ur ban air quality has being improved and urban dust pollution prevention has achieved remarkable successes. There is generally low inc-idence of acid rain in the region. Acid rain is observed only in some areas and its distribution is in relative stability. Water quality deterioration in the overall trend has been prevented; the trend of surface w ater pollution has been alleviated; city noise pollution has been effectively controlled; and the quality of traffic noise and urban noise has been sig nificantly improved.
