Abstract

An environment risk sorting method includes preparing a plant environment database for storing several pieces of environment risk data for abandoned plants; using a first risk evaluation module, based on the environment risk data, to generate a first risk evaluation result for each abandoned plant; using the first risk evaluation result to generate an environmental site evaluation list, which in turn, generates an environment site evaluation data of each abandoned plant and updated environmental risk data; using a second risk evaluation module, based on the environment site evaluation data of each abandoned plant and the updated environmental risk data, to generate a second risk evaluation result for each abandoned plant; and using the second risk evaluation result for each abandoned plant to generate an investigation list as a basis for follow-up investigation.
