摘要: 为了能够有效减少酸雨对日照市生态系统、建筑物和人体健康的危害,加强和开展对酸雨的控制提供决策依据,利用日照市2006—2012年酸雨观测资料、污染物排放量资料,统计分析了酸雨气候变化特征,研究了降水、风、大雾、海洋气溶胶、污染物等条件对降水pH值和酸雨频率的影响。研究表明:(1)近年来日照市酸雨出现次数整体呈上升趋势,强度和频率有明显的年、季变化,夏、冬季酸雨污染较重。(2)降水量、风向、风速、大雾对酸雨的频率影响较大。(3)酸雨pH值与SO2、NO2 的排放量呈现出明显负相关关系,特别是沿海地区海洋气溶胶对pH值影响显著。

Abstract: In order to effectively reduce the hazard of acid rain to ecosystems, buildings and human health in Rizhao City, provide the decision basis for the control of acid rain, based on the observation data of acid rain and pollutant emissions data in Rizhao during 2006-2012 years, the author analyzed the characteristics of climate change of acid rain and studied the effects of rainfall, wind, fog, marine aerosol and other conditions pollutants on the pH value of precipitation and acid rain frequency. The research shows that: (1) as a whole, acid rain frequency in recent 7 years in Rizhao was on the rise. The year and season change of it’s strength and frequency was obviously. Relatively summer and winter were heavier pollution seasons. (2) Rainfall, wind direction, wind speed and the fog had a greater influence on the frequency of acid rain. (3) The pH value of acid rain and SO2, NO2 emissions presented a significantly negative relationship. Especially in coastal areas, marine aerosol significantly impacted on pH.
