全球气候变化所引致的不利影响对海岸带地区生产生活产生严重威胁。本文采用熵值法和改进的耦合协调度模型，基于ArcGIS对研究时间内山东省沿海七个城市的脆弱性以及内部协调性进行处理，深入探讨沿海城市脆弱-协调性的时空演化趋势。结果表明：七个城市脆弱性程度的非均衡性较为显著，协调发展水平均处于过渡发展以及不平衡发展状态，社会滞后和经济滞后成为影响协调发展的主要类型；除青岛市和烟台
市外，整体脆弱性较低且无明显下降趋势，耦合协调水平较低且无明显升高态势；七个城市脆弱性水平与三个子系统耦合协调度具有一定的空间重合性。
The adverse effects of global climate change pose a serious threat to productive life in coastal areas. This paper uses entropy and improved coupling coordination degree model，based on ArcGIS to deal with the vulnerability and internal coordination of the seven coastal cities of Shandong Province during the study period，to explore the trends of the vulnerability-coordination spatial-temporal of coastal cities. The results show that：①the non-equilibrium of the vulnerabilities of the seven cities are significant，the average level of coupling coordinated degree is all in the transitional and the imbalance development，social and economic lags become the main types affecting the coordinated development；②except for Qingdao and Yantai city，there is no obvious downward trend of the overall vulnerability，the coupling coordination level is low and there is no obvious upward trend；③the vulnerabilities and the three subsystems’ coupling coordination levels of the seven cities have a certain degree of spatial congruity.
