  • 摘要: 本文对内陆干旱区（民乐县）2013年6月-2014年5月收集的降水样品pH值、EC和主要阴阳离子浓度进行了测定和分析.结果表明，民乐县降水样品的pH值的变化范围为6.84-8.78，平均值为7.41，pH值在四季中的大小顺序为：冬季 > 春季 > 秋季 > 夏季.而民乐县降水样品EC的平均值为167.80 μS·cm-1，变化范围17.4-848 μS·cm-1，四季中EC的大小顺序与pH值在四季中的大小顺序一致；pH与降水量呈正相关关系，但显著性不高，同时也与与相对湿度呈正相关关系，而pH值与气温也呈负相关关系，显著性较降水量的高.与pH值不同的是，电导率与降水量、气温和相对湿度均负相关关系；通过对典型沙尘事件的分析表明，pH值会随着沙尘事件的发生主要表现出降低的趋势，而电导率会随着沙尘事件的发生呈现增加的趋势，在沙尘事件发生后离子浓度出现最高值的离子有：Na+、Mg2+、NH4+、Cl-和SO42-，而沙尘事件前后离子浓度变化程度由大到小的顺序为SO42-、Cl-、Na+、NH4+和Mg2+.
    Abstract: This work determined and analyzed the pH value, EC and the concentrations of main anion and cation of precipitation samples collected from June 2013 to May 2014 in the inland arid area(Minle county). The results showed that, the range of the pH value of the precipitation ranged from 6.84 to 8.78, and the mean was 7.41. The order for season was winter > spring > autumn > summer. The average of EC was 167.80 μS·cm-1, and the variation range was from 17.4 to 848 μS·cm-1. The order for season was the same as pH value. The positive correlation between pH value and precipitation, but the significance was not high. Meanwhile, the positive correlation between pH value and relative humidity, but pH value and air temperature showed negative correlation and the significance was higher than precipitation. By contrast, EC and precipitation, air temperature and relative humidity showed negative correlation. Through the analysis of typical sand dust events, the pH value decreased and the electrical conductivity incerased with the occurrence of sand dust events. The concentrations of Na+,Mg2+,NH4+,Cl- and SO42- reached to the highest value after the dust events occurred. The order of ion concentration change after dust everts was SO42-、Cl-、Na+、NH4+ and Mg2+ in dust events before and after.
