Provided a salt production automation system utilizing three-dimensionally structured evaporation fields. The salt production automation system utilizing three-dimensionally structured evaporation fields includes: evaporation fields which have collection pools (SWT) and are installed in at least two separate places; a plurality of evaporation members which are three-dimensionally arranged in the evaporation fields to make seawater flow downwards; and a seawater supply unit which supplies seawater to the evaporation members so that seawater can flow downwards from the evaporation members, wherein among the evaporation fields, the number of evaporation members gradually decreases from the first stage evaporation field to the final stage evaporation field.
