摘　　要： 以天津、河北、山东、辽宁4个环渤海省市为研究对象,构建城市化和海域承载力评价指标体系,运用熵值法测算城市化和海域承载力的权重,利用耦合度模型和耦合协调度模型衡量两者之间的协调程度,最后运用变差系数法分析其差异及演进规律。结果表明,环渤海四省市的城市化与海域承载力综合水平的耦合度均高于0.85,耦合协调度均在0.45以上;天津市和辽宁省的耦合度和耦合协调度更高且相对稳定,山东省和河北省的耦合度和耦合协调度较低且波动相对较大。环渤海地区四省市的变异系数小于0.01,说明地区间的差异整体不大。总的来说,目前环渤海四省市的城市化与海域承载力处于稳定协调的发展状态。 This paper, taking Tianjin, Hebei, Shandong and Liaoning in Bohai rim as the studying cases, establishes an index system to evaluate urbanization and sea area carrying capacity, uses entropy to give the weights to urbanization and sea area carrying capacity, employs coupling model and coupling coordination model to measure their coordination degree, and applies the differential coefficient to analyze its difference and evolution rules. Results show the coupling degree of urbanization and sea area carrying capacity of the four stated-above provinces in Bohai rim is over 0. 85, and coupling coordination degree is over 0. 45, both higher and stable in Tianjin and Liaoning, lower and largely fluctuated in Shandong and Hebei. Their differential coefficient is less than 0. 01 , indicating a minor regional difference. It is concluded that the urbanization and sea area carrying capacity is in a stably coordinated status.
