海岸带土地-水-生物多样性的空间联结机理及海陆统筹研究

海洋科学的空间-社会性日益凸显，海岸带是海洋科学、地理科学乃至管理科学交叉融通研究的理想试验区。本项目拟采用弹性评价、网络分析、高分辨率数据挖掘等多学科集成方法，在申请人已提出的海岸带土地-水-生物多样性联结框架基础上，拓展其空间及社会属性，识别陆海空间关键要素，划分海岸带脆弱、安全运行和弹性空间，分析网络构成要素(驱动-关键物种和空间-生态系统服务-社会系统-行动)在上述三大空间中的联结机理，提出海岸带陆海统筹空间优化行动和策略。通过项目研究，最终回答：是否存在及如何测度海岸带“土地-水-生物多样性”空间联结？如何划分海岸带脆弱空间、安全运行空间和弹性空间？弹性空间的研究如何为海岸带海陆统筹提供科学的理论与决策支撑？本项目探索在传统海洋科学研究中引入社会因素，孕育新的学科增长点，提高海洋空间综合认知水平，为国家海陆统筹战略以及在海岸带区域实现联合国可持续发展目标提供科学支撑。

Coastal zone has become a perfect example for cross-cutting research of marine science, geographical science and management science in that space-social attributes of marine science has been increasingly prominent. This project aims to develop a multi-disciplinary framework involving resilient assessment, network analysis, and high-resolution data collection to firstly identify key factors of land-sea space; then divide coastal zone into venerable, safe operated and resilient space; additionally analysis the spatial nexus mechanism of network components (drivers - key species and space - ecosystem services - social systems - action) in the above three spaces; finally propose spatial optimizations for the land-sea integration. This framework based on coastal Land-Water-Biodiversity Nexus we have proposed but further enriched space-social attributes. We will obtain a deep understanding of coastal Land-Water-Biodiversity Nexus, promote the classification of various functional space of coastal area, and explore how mechanism study of resilient space will scientifically guide land-sea integration both theoretically and practically. The highlights of this study lie in introducing social-factor into traditional marine science, creating novel development of the discipline, strengthening integrated understanding of marine space, and providing scientific support for China’s land-sea integration strategy and achievement of United Nations Sustainable Development Goals in coastal region.
