海洋经济可持续发展系统交互胁迫关系验证及协调度测算——以辽宁省沿海六市为例

基于交互胁迫理论,对辽宁省沿海六市2007~2012年海洋生态、社会、经济三个子系统间的交互胁迫关系进行验证,并运用耦合模型进行时空协调度测算。结果表明:三个子系统之间存在着明显的交互胁迫关系,这种动态耦合关系在演化周期内呈现出双指数函数的变化规律,且演化轨迹是一条双指数曲线;通过测算耦合协调度,得出大连市海洋经济可持续发展系统总体耦合协调度高于其他五市,基本处于中级协调发展阶段,其他五市耦合协调度不高,基本呈现波动上升态势,且海洋生态-经济系统的耦合协调度处于波动下降态势,生态压力指数较大,可持续发展水平亟待提高。

The stress relationship verification system interaction and coordination of the sustainable development of marine economy measure -a six coastal city in Liaoning province

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.
