摘要
采用改进的耦合度、耦合协调度模型以及核密度估计等方法,以环渤海地区为研究对象,对2000—2014年环渤海地区海洋经济发展水平和海域承载力进行综合评价,并对两者之间耦合度与耦合协调度进行时空序列分析。结果表明:环渤海地区海洋经济发展水平和海域承载力空间分异明显,海洋经济发展水平的提升幅度高于海域承载力的增强幅度;15年来环渤海各地区海洋经济发展水平与海域承载力的耦合度平均值范围在0.878~0.967之间,河北处于磨合耦合类型,其它地区处于高水平耦合类型,耦合协调度平均值范围处于0.604~0.749之间,且耦合协调度水平波动增长,逐渐趋于最优状态;2014年环渤海地区海洋经济发展水平和海域承载力之间的耦合度空间分异格局为山东>辽宁>天津>河北,耦合协调度空间分异格局为:天津>山东>辽宁>河北。
By t he model of the improved coupling degree and coupled coordination degree, and nuclear density estimation, taking the Round-the-Bohai Region as the research object, this article conducted the comprehensive evaluation of marine economic development level and sea area carrying capacity in the Round-the-Bohai Region from2000 to 2014. Spatio-temporal sequence analysis of the degree of coupling and the degree of coupling between the two was carried out. The results show that：（1） The spatial distribution of marine economic development and sea area carrying capacity is significant in the Round-the-Bohai Region, and the extent of marine economic development is higher than that of the sea area;（2） In the past 15 years, the average coupling degree between the marine economic development and the sea bearing capacity ranged from 0.878 to 0.967. Hebei province was in the type of run-in coupling and the other regions were in the high-level coupling type. The average degree of the coupling coordination was in the range of 0.604-0.749, which gradually increased in a fluctuating and became the optimal;（3） The spatial heterogeneity of the coupling degree between the marine economic development level and the sea area carrying capacity in 2014 was： Shandong 〉Liaoning〉 Tianjin 〉Hebei, the coupling coordination space differentiation pattern： Tianjin〉Shandong〉Liaoning〉Hebei.
