环渤海地区海洋资源承载力与海洋经济发展潜力耦合关系研究

On the Coupling Relationship between Marine Economic Developing Potential and Marine Resources and Environment Carrying Capacity in Bohai Sea Rim Region

海洋资源环境承载力和海洋经济发展潜力之间存在着正向关联关系。采用熵值法测度了环渤海地区海洋资源环境承载力和海洋经济发展潜力,运用耦合度模型和耦合协调度模型衡量了两者之间的耦合协调程度,并运用变差系数法分析其地域差异及其演进规律。研究结果表明:环渤海地区海洋经济发展潜力与海洋资源环境承载力耦合度普遍高于0.8,较少年份出现低于0.8现象。空间上表现出天津市和山东省耦合度及耦合协调度双高的稳定耦合协调状态,河北省和辽宁省耦合度较低且波动大,地区间差异明显。计算地区间耦合度变异系数得出,变异系数值不断下降,地区间差异有明显下降趋势。

The relationship between marine resources and environment carrying capacity and ma-rine economic developing potential associates positively.Entropy method was chosen to measure the resources and environment carrying capacity of marine and marine economic developing poten-tial in Bohai Sea Rim region in this study.Both of coupling model and coupling coordination de-gree model were used to measure the degree of coupling coordination between the two positive re-lated parameters.Coefficient of variation method was applied to analysis the geographical variance and evolution rule.The result demonstrates that the coupling factor between the potential of ma-rine economic development and the resources and environment carrying capacity of marine in Bo-hai Sea Rim region is generally greater than 0.8 and in few years less than 0.8.The coupling de-gree and coupling coordination degree of Tianjin and Shandong Province are both high and in steady coordination state.While the two parameters between Hebei and Liaoning province are in low coupling state,which shows significant differences between regions.After calculating the cou-pling coefficient of variation within regions,it can be concluded that with the declining of variation coefficient the regional differences have a evident downward trend.
