The invention discloses an LSTM-based single-phase earth fault line selection method and system. The method carries out data collection and data processing, and comprises the steps of collecting a plurality of conventional electrical quantities monitored by a power distribution network based on a scheduling platform, and carrying out the data cleaning operation, thereby obtaining original characteristics, selecting characteristic quantities, namely constructing a plurality of new characteristics according to the collected electrical quantities, obtaining the importance degree of each characteristic from the original characteristics and the new characteristics by adopting a plurality of characteristic quantity extraction algorithms, and selecting the characteristic quantities according to the importance degrees, establishing an LSTM-based single-phase earth fault line selection model, wherein the model comprises an input layer, three hidden layers and an output layer, the input layer is determined by the chara
