Abstract: The salt well water，also called underground brine with the low concentration，is caused by the seawater intrusion in coastal areas, and mainly distributes in the rudaceous or arenaceous shore plain of the Bohai bay and Liaodong bay and so on. Taking the Xingcheng modern fishery garden as case study area where the salt well water resources have been developed for local aquiculture in factories，the evaluation result of the salt well water resources with groundwater flow numerical simulation suggests that the groundwater balance is in the negative state. At the same time，some suggestions and tactics, which include strengthen the cyclic utilization of water resources, constructing engineering measures such as tidal barrage, building the dynamic monitoring net of the salt well water, will be of significance for the rational exploitation and utilization of the salt well water to avoid these environmental problems, such as seawater intrusion, drinking water quality deterioration.

Key words: salt well water, water resources evaluation, exploitation and utilization, coastal areas
