摘要
海岸带长期承受陆海生态风险的交互扰动,基于陆海统筹的系统性治理是提升其生态韧性的重要途径。海岸带生态管治条块分割的问题突出,生态系统具有相对独立性的海湾,作为陆海统筹的实施单元,为海岸带生态韧性测度与规划提供了新视角。在梳理海湾生态要素构成的基础上,分析陆海生态灾害诱因及其作用方式,进而厘清海湾生态系统的韧性响应机制。在陆海统筹目标下构建了海湾生态韧性测评指标体系,并以厦门湾为空间单元展开实例研究,采用相关模型剖析厦门湾陆域-海域生态韧性的耦合协调特征及演进驱动因子;聚焦厦门湾生态韧性薄弱之处,从构筑生态安全格局、分级整治韧性空间、联动管控韧性要素、建构跨界协同机制4个维度提出陆海统筹治理策略,以促进厦门湾生态系统可持续发展。该研究的理论建构及实践总结可为其他海湾单元生态文明建设提供参考。
Coastal zones have long been subject to dynamic interactions between land and sea,which have led to complex ecological risks,such as habitat fragmentation,degradation of ecological functions,destabilization of ecological structures and drastic reductions in biodiversity.The establishment of a systematic governance framework based on land-sea integration is essential and important for strengthening the resilience of these fragile ecosystems.However,the current situation is characterized by a series of obvious problems:conflicting goals of economic development and ecological protection in the coastal zone,prominent administrative fragmentation of ecological governance,and a lack of synergistic thinking in various types of eco-spatial planning,which hampers the implementation of effective management strategies.Considering those challenges,gulfs with relatively independent ecosystems have emerged as key spatial vectors,offering a promising avenue for implementing an integrated land-sea management approach.Their unique characteristics provide new perspectives for assessing and planning the ecological resilience of coastal zones.By sorting out the ecosystem components of the gulfs,researchers can gain insight into the root causes and generation mechanisms of land-sea ecological hazards.This analysis lays the foundation for clarifying the inherent resilience response mechanism of the Gulf ecosystem.In addition,under the overall goal of land-sea integration,a complete set of gulf ecological resilience indicator assessment system is constructed.Taking Xiamen Gulf as a case study,the researchers explored the complexity of its ecological problems and analyzed the coupling and coordination characteristics of the land-sea resilience of Xiamen Gulf and its evolutionary drivers using relevant models.Turning attention to the weak links in the ecological resilience of Xiamen Gulf,efforts have been made to embark on proactive measures to strengthen its weaknesses.This involves formulating a sound ecological security pattern for the gulf and stabilizing the structure of the resilience network,and delineating and repairing affected resilience spaces and enhancing ecosystem values,and establishing linkage governance and regulatory mechanisms for resilient elements,as well as promoting multi-stakeholder and multi-level cross-border coordination,to enhance the overall resilience of Xiamen Gulf to adapt to external environmental changes.The theoretical foundations and practical experience gained from this study are not limited to Xiamen Gulf,but can also provide valuable ecological and environmental recommendations for other gulf units facing similar challenges.By distilling and building on the best practices gained from this study,planning decision makers and stakeholders can work to promote more resilient and sustainable coastal ecosystems around the world.
