| 摘 要： | 利用广西10个酸雨监测点2003-2009年的酸雨资料,采用经验正交函数分解（EOF）的统计方法,分析了广西区域酸雨的空间分布特征与时间变化趋势。结果表明,广西酸雨频率呈波动性变化,特别是2004-2008年酸雨污染趋势加剧;全区域酸雨频率变化一致,东部、西北部明显高于其他地区,酸雨污染严重的地带已扩展到西部;个别年份广西东北部与西南部的酸雨频率变化反位相。 |

| Abstract: | Based on acid rain data from ten monitoring sites in Guangxi from 2003 to 2009,the temporal and spatial distribution characteristic of acid rain in Guangxi were analyzed by means of empirical orthogonal function resolution(EOF).The results showed that there was fluctuating change of acid rain frequency in Guangxi,and acid rain pollution became severer in 2004-2008;acid rain frequency changed conformably in the whole region and it was higher in eastern and northwestern Guangxi,while acid rain pollution becam... |
