| 摘 要： | 根据廊坊市区"十五"期间降水组成成份的监测结果分析得知:廊坊市区酸雨频率呈上升趋势,SO42-为降水的主要致酸物质,NO3-的贡献有所增大。取暖期降水的pH值低于非取暖期,取暖期降水的总离子浓度则高于非取暖期。

| Abstract: | According to the analysis of the ingredients of the precipitation in Langfang during the period of the Tenth Five-year Plan,the acidification frequency has increased.The SO42-was the predominant acidic substance in the precipitation.NO3-contribution has also increased.Compared with non-warmed period,the PH is lower and overall ion concentration is higher in warmed period. |

| Keywords: | precipitation PH overall ion concentration developmental tendency |
