青岛地区酸沉降现状的研究

Study on Current Situation of Acid Deposition in Qingdao Area

青岛地区的降水酸化问题在我国北方具有一定的代表性。该研究在对青岛地区降水酸度的时空分布、酸性降水与气象条件的关系进行长期常规观测及集中综合观测，取得大量数据的基础上，重点分析了青岛地区酸沉降的现状及发展趋势。结果表明：青岛地区降水酸度和频率与ＳＯ２环境浓度有关，ＳＯ２浓度较高的市区降水酸度和频率亦高，市郊较低，远郊最低；降水酸度季节变化明显，冬、春季高，夏、秋季低；

Rainwater acidification in Qingdao area can represent that in northern area of China to a certain degree. The current situation and tendency of acid deposition in Qingdao area were emphatically analyzed after a large number of data were obtained through long term conventional observation and short term comprehensive observation for distribution of rainwater acidity in time and space, and the relation between acid rain and meteorological condition. The results show that rainwater acidity frequency in Qingdao area are related to the environmental concentration of SO 2, i.e., rainwater acidity and frequency are high in downtown where SO 2 concentration is high, lower in suburbs , and lowest in outer suburbs; seasonal variation of rainwater acidity is obvious, i.e., high in winter and spring, low in summer and autumn; the tendency of acid rain is controlled by emission of SO 2.
