铜川市十年空气质量变化趋势及其对策分析

Analysis of Air Quality Changing Trend in Tongchuan City for Ten Years and Countermeasures

以铜川市三项主要污染因子为基础,采用对比法、污染指数法、污染负荷系数法、秩相关系数法等统计方法,分析了污染物年均浓度、月浓度及其变化趋势。得出了空气质量逐年好转,空气污染为典型的煤烟型污染类型且逐步由单一性向复合型转化,颗粒物主要来源于煤炭燃烧、工业排放的结果。提出了今后大气污染防治须加大投入、加强工业企业脱销工程的力度,减少城市建筑及道路扬尘污染等。

Based on three major pollution factors in Tonghcuan, the article adopts the comparison method, the pollution index method, the pollution load coefficient method, rank correlation coefficient method to analyze the annual pollutant concentration, monthly concentration and its change trend. The article concludes that the air quality improves year by year. Air pollution belongs to a typical coal-- smoke pollution type and gradually changed from simplicity to complexity. The particles mainly come from burning coal and industrial emissions. Prevention and control of atmospheric pollution must invest more in the {uture. The government should strengthen the industrial enterprises＂ denitration project and pay special attention to the urban construction and road dust pollution.
