| 摘 要： | 根据1992年6月到2004年12月的酸雨观测记录,对近10余年天津市酸雨的变化规律和趋势进行了统计分析。结果表明:天津市酸雨发生呈明显的季节性变化,酸雨发生频次和强度呈现不同的季节变化趋势,酸雨主要分布在夏秋两季,但酸雨较强的季节却是在秋冬季;天津市酸雨呈逐年减少趋势,进一步的分析表明天津地区SO2排放量的逐年减少是酸雨减弱的主要原因。 |

| Abstract: | Based on the measurement records of over 10 years,an analysis is made to reveal the seasonal variation pattern,long term trend and formation causes of acid rain in Tianjin.The statistic results show that obvious seasonal variation patterns exist in both the occurrence frequency of acid rain and the average pH value of precipitation.The acid rains with pH value lower than 5.6 appeared mainly in summer and autumn,but the acid rains with lower pH value appeared in autumn and winter.The result of analysis also shows an obvious decreasing trend of the frequency of acid rain in Tianjin in last 13 years.The possible reasons for this long-term trend are discussed.The reduction of the SO2 emission in Tianjin area is considered as an important contribution to the decreasing trend of the frequency of acid rain locally. |
