The invention provides an atmospheric environment tracing evaluation method and system based on an industrial park. The system comprises an abnormal event monitoring unit, an abnormal event retrieval unit, an abnormal event tracing unit, a pollution prediction unit, a management and control task distribution unit, a management and control task tracking unit, an event evaluation unit and a task flow form unit. The method comprises seven steps of testing, tracing, pre-managing, treating and evaluating, an atmospheric pollution tracing model, a pollution diffusion model and a task flow form are utilized to realize the whole-process closed-loop management of park atmospheric environment management work from early warning, timely response, accurate tracing and scientific treatment, the delay and blindness of conventional artificial offline judgment are reduced, and the management efficiency is improved. Early warning information receiving, pollution traceability and situation prediction of daily pollution events, proposing of enterprise governance measures afterwards, supervision and management of enterprise governance work and governance effect evaluation after rectification are achieved.
