摘要
根据博乐市2005—2010年降水数据,对酸雨发生的原因进行了分析。分析结果表明:博乐市地形适合水汽输入,存在远距离污染物跨境传输和产生连续大降雨的条件,使其境内产生酸雨的可能性加大;酸雨发生在冬季采暖期,且NO3-浓度比未发生酸雨时略高;另外,博乐市属北方干旱区城市,土壤偏碱性,降水总体为偏弱碱性特点不变。除以上主要因素外,由于酸雨产生机理复杂、影响因素众多,博乐市产生酸雨的其他原因有待继续探究。
According to Bole 2005 - 2010 precipitation data, the mason of acid rain was analyzed. The results showed that bole terrain fit for water vapor input, so there were long distance cross- border transport of pollutants and continuous heavy rainfall. The possibility of acid rain increased. Acid rain occurred in the winter heating period, and NO3^ - concentration was slightly higher. As a north arid city, bole soil showed alkaline. Otherwise, Weak alkaline characteristics of bole precipitation remain unchanged. In addition, as complex mechanism and important impact, other reasons on acid was incentived to further study.
