摘　　要：沿海城市的经济快速发展和土地利用与海洋生态环境之间关系密切。陆海统筹的背景下,科学了解陆海生态环境质量演变和空间分布特征,探究两者的耦合协调关系对提升陆海生态安全统筹具有重要的实践意义。以中国沿海53个城市为例,采用“活力-组织-恢复力(VOR,Vitality-Organization-Resilience)”模型评价陆地生态系统健康状况,采用TOPSIS法通过构建指标体系评价海洋生态环境质量,采用耦合协调度模型分析陆海生态环境质量耦合协调水平,并提出相关建议。结果表明:1)2010—2020年沿海城市陆地生态系统健康呈现“北低南高”的分布格局,以杭州湾为主要分界线;2)2010—2020年沿海城市海洋生态环境质量呈现趋好的态势,海洋生态环境质量:沿东海经济区<环渤海经济区<沿黄海经济区<沿南海经济区;3)2010—2020年沿海城市陆海生态环境质量耦合程度进一步加强,且南部城市协调度高于北部。研究为中国沿海地区陆海生态环境管理、因地制宜地开展生态修复工作提供科学依据,对陆海生态系统的健康协同发展具有重要意义。The rapid economic development and land utilization in coastal cities are closely intertwined with the marine ecological environment.Against the backdrop of integrated land⁃sea coordination planning,comprehensively understanding the evolution and spatial distribution characteristics of land⁃sea ecological environmental quality and exploring the coupling and coordination relationship between them holds significant practical implications for enhancing the coordinated management of land⁃sea ecological security.The comprehensive evaluation of ecological environment quality in both land and sea has always been a hot topic of academic research.Having a comprehensive understanding of the ecological environment quality in both land and sea is a fundamental issue in studying the overall ecological security of land and sea,and is also a prerequisite for effective planning.Taking 53 coastal cities in China as a case study,this research employs the"Vitality⁃Organization⁃Resilience(VOR)"model to assess the health of terrestrial ecosystems.The vitality of terrestrial ecosystems is reflected by Net Primary Productivity(NPP),while landscape heterogeneity,landscape shape,and landscape connectivity represent the organization of terrestrial ecosystems.Habitat quality represents the resilience of terrestrial ecosystems.The TOPSIS method is utilized to evaluate the quality of the marine ecological environment by constructing an index system.Construct an index system from the three aspects of marine water environmental quality,marine sediment environmental quality,and marine biological environmental quality to reflect the level of marine ecological environment quality.Furthermore,a coupling coordination degree model is employed to analyze the level of coupling and coordination of land⁃sea ecological environment quality.Relevant suggestions are proposed for cities with imbalanced development of land and sea ecological environment quality,as well as those transitioning from coordination to imbalance.The findings indicate tha
