Abstract: According to the research of the marine resources and environmental carrying capacity, the evaluation system for early-warning of marine environment carrying capacity was built combined with environmental requirements for division of marine functional zonation and spatial analysis techniques.The early-warning of marine environment carrying capacity was calculated from 2013 to 2016 in Bohai sea, the result showed that the method was feasible and could propose the different of early-warning area in Bohai Sea.It could provide a new ideas to evaluating early-warning of marine environment carrying capacity and provide technical support in making policy for the marine administrative department.
