摘    要:运用R/S分析(Rescaled Range Analysis)方法对连云港市3个大气环境定位监测点近10年来的SO2、NOx和TSP序列数据进行了时间序列的长程相关性分析.结果表明,连云港市SO2、NOx和TSP月均值序列的Hurst指数在0.500~1.000,表现出明显的长程相关性,并且这种相关性程度的强弱随着城市功能区的不同而表现出一定的差异.研究结果对于认识连云港市城市大气环境质量变化过程和科学制定环保决策具有重要意义.

Abstract:The rescaled range analysis (R/S) method was employed for long-term correlational assessment of air pollutants' time series in Lianyungang based on the data collected by three monitoring stations over the past 10 years. The results showed that the Hurst Exponent of the monthly means for SO2, NOX, TSP time series were within 0.500~1.000 indicating the pollutants' time series were correlated and that the correlation was dependent on the function zones. Such analysis, which accounts for the dynamic changes in air quality, produces results useful for making wise and scientific environmental protection decisions.
Keywords:Air pollutants Time series R/S method Lianyungang city
