摘要:
根据2006年1月-2010年12月的酸雨监测数据,对扬州地区酸雨的变化规律和趋势进行了统计分析。结果表明: 扬州地区酸雨主要集中在扬州市区与仪征城区,“十一五”期间,扬州市区酸雨呈逐年减少趋势,仪征城区大气污染严重,降水pH年均值均小于5.6,经评价扬州市区属于非酸雨区-较重酸雨区,仪征城区属于轻酸雨区-重酸雨区。高邮、江都、宝应城区从2007年起无酸雨出现。仪征城区酸雨主要是由燃煤型和燃油型混合空气污染造成的,近年来随着机动车拥有量的迅速增加,各种机动车排放的尾气已成为形成酸雨的重要原因,应引起重视。

Analysis on the Situation and Cause of the Acid Rain in Yangzhou Area
Abstract:
According to the 2006 January - 2010 December precipitation monitoring data, the change regularity of acid rain in Yangzhou area and the trend is analyzed statistically. The results show that acid rain in Yangzhou area is mainly concentrated in the urban area of Yangzhou and Yizheng city. During the “Eleven five” period, acid rain in Yangzhou urban area shows a decreasing trend. Air pollution in Yizheng City is serious, the annual average pH is less than 5.6. The evaluation of Yangzhou city belongs to non acid rain zone--heavy acid rain zone, and Yizheng city belongs to light rain area--the heavy acid rain zone. No acid rain appeared in Gaoyou, Jiangdu, Baoying city since 2007.. The cause of Yizheng city acid rain is mainly composed of coal and fuel oil mixed air pollution, so the acid rain type belongs to mixed type. In recent years, with the rapid increasing of vehicle ownership, a variety of motor vehicle exhaust emissions has become the important cause for the formation of acid rain which we should pay attention to.
