| 摘要: |
| 选取1991~2003年柳州市降水pH值、酸雨率,1995年~2003年柳州市年耗煤量,1996年~2003年柳州市降水主要离子SO42-/NO3-的比值等数据,通过计算Spearman秩相关系数分析近年来柳州市的酸雨变化趋势。结果表明,柳州市从1996年开始针对酸雨污染采取的治理对策取得了一定成效,使酸雨污染得到了有效控制。但是,柳州市大气污染有向煤烟型与机动车尾气混合型过渡的趋势,柳州市要加强机动车尾气的治理工作。 |

| Abstract: |
| The variation tendence of acid rain in Liuzhou recent years is analyzed using Spearman correlation.The data collected include pH values and acid rain frequencies during 1991 to 2003,annual coal consumptions of the city during 1995 to 2003,the SO42-/NO3- of rainfall during 1996 to 2003.It is revealed that the acid rain pollution in Liuzhou city has been improved since a series of anti-pollution activities were carried out in 1996.The pollution in Liuzhou city is going to be a mixture of coal burning and automobile emission.The control and management of exhaust gas of vehicles needs to be strengthened |
