Abstract：Based on the theory of interaction stress, the relationship of interaction stress between three subsystems of marine ecological, social and economic in the coastal area of six cities in Liaoning province was verified and calculated the spatial and temporal coordination degree by using the coupling model from2007 to 2012.The results show that there are obvious interaction stress relationship among the three subsystems, the dynamic coupling relationship in the evolution cycle is a double exponential function, and the evolutionary trajectory is a double exponential curve.Through the calculation of coupling coordination degree, the overall coupling coordination degree of Dalian marine economic sustainable development system is higher than the other five cities and has a downward trend in fluctuation, the degree of other five cities are not high, and the marine ecological-economic System coupling coordination degrees has a downward trend in fluctuation, ecological pressure index is larger, the level of sustainable development needs to be improved.
