摘要
以南昌市城区"十五"期间的大气环境质量监测数据为依据,采用空气污染综合指数法评价其大气环境质量,并运用Spearman秩相关系数预测其发展趋势。结果表明南昌市"十五"期间大气环境质量为轻度污染,主要污染物为降尘和可吸入颗粒物。SO2和NO2的浓度有上升的趋势,但不显著,PM10呈显著下降趋势。同时分析了南昌市大气污染特征及原因,提出了改善大气环境质量的对策和建议。
Based on the major air pollution monitoring data of Nanehang City during the ＂10th Five - Year Plan＂ period, the air quality of Nanchang City was assessed using atmospheric pollution composite index and its development trend was forecasted by using Spearman rank correlation coefficient. The results showed that the air quality of Nanchang city was slighted polluted and the main pollutants are dustfall and PMl0. The concentration of sulfur dioxide and nitrogen dioxide displayed upward trend but not significantly, and that of PM10 showed downtrend obviously. The characteristics and genesis of air pollution were discussed as well, and strategy and suggestion to improve air quality was put forward.
