【摘要】 对泸州市2006~2007年降水中阴离子和阳离子监测结果进行了综合分析,降水离子组分当量浓度均值的关系是,SO42->NH4+>Ca2+>NO3->H+>Mg2+>Cl->F->K+>Na+.相关性分析结果表明,除了H+以外,其他各种离子之间均具有显著的相关性.因子分析表明,降水酸度是各离子组成综合作用的结果,并初步推断泸州市降水化学组成的来源.更多还原

【Abstract】 A comprehensive analysis was made on the anion and cation concentrations in the precipitation samples in Luzhou City during 2006 to 2007.The decrease order of equivalent concentration of the main ions is:SO2-4>NH+4>Ca2+>NO-3>H+>Mg2+>Cl->F->K+>Na+.The correlation coefficients reflect that all the ions have significant correlation ships except of H+.Factor analysis shows that the acidity of precipitation is an integrated result of all the other precipitation chemical ions,and the possible sources of the precipitation chemical constituent were deduced primarily.更多还原
