基于社会行为者视角的山东沿黄地区人水耦合系统结构研究

揭示人水系统要素的组织结构是社会水文学和人地耦合系统研究的学科前沿，山东沿黄地区人水耦合系统结构的刻画将为黄河下游流域生态保护和高质量发展提供系统性、整体性、协同性的科学支撑。面向流域人-水关系的系统刻画方法学难点，本项目应用社会-生态网络分析，将社会行为者和资源要素表述为节点，将节点之间的依存关系表达为链接，以结构化视角理解环境治理中的社会行为者冲突成因和冲突缓解路径。项目基于社会行为者访谈与地理空间数据分析，依托感知、价值、意愿等指标建构社会-生态网络，揭示河口湿地生态治理、农业节水高效利用、黄河文旅品质提升等目标下的人水生态、生产、生活子系统结构特征和统筹三项目标的人水耦合系统结构特征，进而建构包含节点潜力和网络连通度在内的系统恢复力评价体系，识别提升山东沿黄地区人水耦合系统恢复力的关键节点和关键路径，以期为黄河下游流域的可持续自然资源管理提供多主体、结构化的协作治理依据。

Revealing the organizational structure of the elements in a Human-Water system is the frontier of Socio-hydrology and Coupled Human-Natural System research. The characterization of Coupled Human-Water System structure in the areas along the Yellow River in Shandong province will provide systematic, integrated and coordinated scientific support for ecological protection and high-quality development in the downstream of Yellow River basin. Aiming at the methodological difficulties in the systematic description of the human-water relationship in a basin, this project applies the social-ecological network analysis to understand the causes of social actors' conflicts and mitigation paths of the conflicts in environmental governance from a structural perspective, which expresses the social actors and ecological resources as nodes, and express the relationship between nodes as links. The social-ecological network will be constructed based on geographical spatial data analysis and interviews on social actors including the survey indices such as perception, value, and intend. The Human-Water Subsystem structures with ecology, production and living characteristics will be characterized in the aims of ecological management in estuarine wetland, promotion of water-efficient agriculture, and quality improvement of Yellow River culture and tourism, respectively. The Coupled Human-Water System structure, which is a whole of the abovementioned three subsystem structures, will also be characterized. Then a resilience evaluation system including node potential and network connectivity will be constructed to identify the key nodes and critical paths for improving the resilience of the Coupled Human-Water System in the areas along the Yellow River in Shandong province. The outcomes are providing a multi-agent and structured cooperative governance basis of sustainable management on natural resources in the downstream of Yellow River basin.
