【摘要】 应用东营市2005年5月到2009年4月高空、地面气象资料和酸雨观测资料及环保局的空气质量监测资料,对黄河三角洲酸雨的气候特征和形成规律进行了研究,并提出了防御对策及建议。研究结果表明:酸雨日数占黄河三角洲有效降水日数的53.7%,主要集中在6～9月与本地降水集中时段相对应。8～9月份酸雨出现的频率最高,3月最低。酸性降水最强出现在秋冬季,最弱出现在春季。酸雨的形成与当地的空气污染和上游地区的污染输送存在一定的关系。更多还原

【Abstract】 The climatic characteristics and the forming regularity of acid rain in the Yellow Rive Delta were studied by using the meteorological data in high-altitude and ground, the observational data of acid rain and the monitoring data of air quality that provided by Environmental Protection Bureau from May 2005 to April 2009 in Dongying City, and the control measures were proposed in this paper. The results showed that the acid raining days account for 53.7% of annual effective precipitation days, which mainly happened from June to September. The highest frequency of acid rain appears in August to September, the lowest frequency of acid rain appears in March. The acid rain has a certain relation to the local air pollution and the polluting transportation from the upstream region.更多还原
