The invention discloses a method and device for automatically identifying similar pollution cases, and the method comprises the steps: (1) obtaining historical pollution cases of a target region, and extracting the pollutant concentration data and meteorological element data of each historical pollution case; (2) calculating the similarity between the meteorological element data of different historical pollution cases to obtain a historical similar meteorological characteristic large class; and (3) calculating the similarity of the pollution concentration curves under each similar meteorological characteristic large class to obtain pollution concentration curve subclasses. According to the method, automatic identification of similar pollution cases can be realized through feature extraction of the meteorological data and the concentration curve related to the pollution process. 一种污染相似案例自动识别的方法和装置，所述方法包括：(1)获得目标区域历史污染案例，提取每个历史污染案例的污染物浓度数据和气象要素数据；(2)计算不同历史污染案例的气象要素数据之间的相似度，获得历史相似气象特征大类；(3)计算每个相似气象特征大类下的污染浓度曲线的相
