EPA PMF5．0在浦东新区降水源解析中的使用研究

摘要

Taking the precipitation source apportionment in Pudong New Area as an example, various cations and anions were discussed by the EPA PMF5.0 model via the monitoring data and uncertain data collection before using , data interpretation, the optimum factor number confirmation before basic model operation and factor contribution ratio variation around the model rotation so as to obtain the cations and anions which possess main contribution.By the use of EPA PMF5.0 model, new research ideas are acquired in fields such as atmospheric precipitation applied in pollution control and management .Besides, it provides reference for source apportionment implemented by grassroots stations.%使用EPA PMF5．0模型，以浦东新区降水源解析为例，按照使用前监测数据和不确定度数据收集、模型运行前数据判读、基本模型运行前最佳因子数确定以及模型旋转前后因子贡献比变化，对降水中多种阳离子和阴离子分别进行讨论，在离子贡献汇总中得到其主要贡献的阴阳离子。 EPA PMF5．0方法的使用，为大气降水在污染源治理和管理等领域提供了新的研究思路，同时也对基层监测站开展源解析具有参考作用。
