沿海城市经济-海洋生态环境-游艇旅游业耦合协调发展分析

Analysis of coupling coordination development among the coastal city economy, marine ecological environment and yacht tourism industry

借鉴物理学中的耦合理论,分析沿海城市经济系统、海洋生态环境系统与游艇旅游业系统三者间的耦合协调作用机理;构建耦合评价模型与指标体系,并基于改进的熵值法,对沿海16个游艇旅游发展重点城市三者的耦合度及耦合协调度进行实证研究;运用皮尔逊相关系数法探讨各因素间相互关系。结果表明:沿海城市经济、海洋生态环境和游艇旅游业发展水平的综合评价值并不高,可进一步分为城市经济滞后型、生态环境滞后型和游艇旅游业滞后型三种制约类型;区域内三大系统耦合度较高,但耦合协调度较低且存在明显的区域差异;系统内部各因素间相互关联。鉴于此,提出游艇城市应因地制宜,协调开发与保护关系,深化产业融合等建议,以促进三大系统较高层次的耦合协调发展。

Using coupling theory in physics, the coupling interaction mechanism among the coastal city economy, marine ecological environment and yacht tourism industry was discussed, and coupling evaluation model and indices of three systems were constructed. Based on the improved entropy method, the model of coupled degree and coupled coordination degree was used to calculate each degree of regional economy, marine ecological environment and yacht tourism industry systems of sixteen coastal cities, and Pearson correlation coefficient method was applied to discuss the internal relationship among various factors in three systems. The results showed that the comprehensive evaluation value of three systems were not high, which could be further divided into three lag types as regional economic lag, marine ecological environment lag and yacht tourism industry lag. The three systems had high coupling degrees, but low coupled coordination degree which had obvious regional differences. There were significant correlations between various factors within the system. Therefore the paper suggests identifying the short barrels according to local conditions, coordinating the relationship between development and protection, deepening the integration of yacht industry in order to promote the coupled development of three systems
