本发明公开了一种基于指纹图谱的城市矿产基地复杂污染源解析方法，通过对城市矿产基地内主要生产、运输、储存环节中所产生的污染物组分及含量进行分析，编制出各具体环节的污染物指纹图谱库，从而实现城市矿产基地污染源解析；包括以下步骤：调查城市矿产基地的生产现状；测定城市矿产基地各环节污染物组分及含量；筛选出各环节的特征污染物，构建对应的污染物指纹图谱，形成污染物指纹图谱库；对该基地或其周边某处环境样品进行组分和含量分析；对比获得的污染物指纹图谱库，对上一步中的待测环境样品进行溯源分析；根据污染物指纹图谱和该基地环境样品溯源分析结果，确认该基地环境样本中污染物的来源环节，并提出合理改进措施。

The present invention discloses a fingerprint based method for analyzing complex pollution sources in urban mineral bases. By analyzing the composition and content of pollutants generated in the main production, transportation, and storage processes of urban mineral bases, a pollutant fingerprint library for each specific process is developed, thereby achieving pollution source analysis in urban mineral bases; This includes the following steps: investigating the production status of urban mineral bases; Determine the composition and content of pollutants in various links of urban mineral bases; Screen out the characteristic pollutants in each stage, construct corresponding pollutant fingerprint maps, and form a pollutant fingerprint library; Conduct component and content analysis on environmental samples from the base or its surrounding areas; Compare the obtained pollutant fingerprint libraries and perform traceability analysis on the environmental samples to be tested in the previous step; Based on the fingerprint of pollutants and the traceability analysis results of the environmental samples of the base, confirm the source link of pollutants in the environmental samples of the base, and propose reasonable improvement measures.
