| 摘 要： | 应用东营地面观测站2005年9月～2008年8月的酸雨观测资料，分析了东营市的酸雨特征，并讨论了酸雨对农业的影响。结果表明：141个降水样本中酸雨频率为55．3％，11月最多，达100％，12月最少为25％；酸雨频率具有明显的季节性，即秋季〉夏季〉冬季〉春季；酸雨的年变化趋势基本呈波浪状，但由于资料的年限较短，还需进一步总结订正；酸雨频率与雨量大小有密切关系，基本按小雨〈中雨〈大雨〈暴雨的次序直线上升；农田长期受酸雨危害会影响土壤的pH值，农田土壤酸性与酸雨强度有正相关关系.当酸雨输入超过土壤缓冲能力时，土壤就会呈现酸化，使土壤的物理化学性质发生变化。由于酸雨是使农田土壤酸化的主要原因，所以建议加强城市排放的严格管理，提高能源利用率；另外还要合理利用土壤，尽量减少土壤的酸性，加强对农田环境的保护。

| Abstract: | Acid rain characteristics were analyzed which applied by acid rain data of ground-based observatories in Dongying from Sep.2005 to Aug.2008,and the impact of acid rain on agriculture were discussed.The results showed that acid rain frequency was 55.3%,up to November,reaching 100%,in December at least 25% among 141 precipitation samples.The frequency of acid rain had obvious seasonal,that was autumn> summer> winter> spring;Change trend of acid rain was high-and low-interlacing,but the data had a shorter peri... |
