Trans-boundary water pollution source analysis method, system and device and storage medium

The invention relates to the technical field of water pollution treatment, in particular to a trans-boundary water pollution source analysis method, system and device and a storage medium. The invention provides a trans-boundary water pollution source analysis method, which comprises the following steps of: firstly, setting a monitoring node in a river reach according to prior knowledge, and taking a to-be-analyzed part of the river reach as a target node; and acquiring the monitoring node with the highest similarity ranking with the water sample component at the target node as an analysis object, performing pollution source analysis on the analysis object, and taking the pollution source of which the influence coefficient on the analysis object reaches a set influence condition as a high-correlation pollution source of the target node. According to the invention, pollution traceability can be timely, rapidly and accurately carried out for any water area. 本发明涉及水污染治理技术领域，尤其是一种跨界水污染源解析方法、系统、装置和存储介质。本发明提出的一种跨界水污
