摘要
海洋生态安全是人类与海洋和谐共存、实现海洋经济可持续发展的基本保障。本文基于2010-2021年的数据,通过构建指标体系和InVEST模型测算环渤海地区海洋生态安全指数,评估其时空演变,并运用GTWR模型分析影响因素及其空间异质性。结果显示:(1)环渤海地区海洋生态安全状况呈阶段性上升,从比较安全级提升至非常安全级;(2)海洋生态安全水平呈现“东西部高、中南部低”的空间格局,差异明显;(3) GTWR模型表明,涉海湿地面积是关键正向驱动因素;海洋科技人才比例和城镇化进程对山东省影响显著,而天津市则更多受涉海湿地面积和城市空气质量达标率影响。
Marine ecological security is the fundamental guarantee for the harmonious coexistence between humans and the ocean,as well as for achieving the sustainable development of the marine economy.Based on data from 2010 to 2021,the marine ecological security index of the Bohai Rim region was calculated by constructing an indicator system and the InVEST model,assessing its spatiotemporal evolution,and analyzing influencing factors and their spatial heterogeneity using the GTWR model.The results show that:①The marine ecological security status of the Bohai Rim region has shown a phased improvement,rising from a relatively safe level to a very safe level;②The ecological security level exhibits a spatial pattern of“higher in the east and west,lower in the central and south,”with significant regional differences;③The GTWR model indicates that the area of coastal wetlands is a key positive driving factor;the proportion of marine science and technology professionals and urbanization progress have a significant impact on Shandong Province,while Tianjin is more influenced by the area of coastal wetlands and the urban air quality compliance rate.
