| 摘要: |
| 【目的】厘清山、水、林、田、湖、草之间的协同和权衡关系，优化红枫湖流域的生态管控分区，制定科学的分区管理措施。【方法】以红枫湖流域为研究区，分析各子系统在全域和局部空间的协同/权衡关系，探讨基于山、水、林、田、湖、草协同理念的生态管控分区方案。【结果】流域内生产区与生态区的空间分异性明显，林地、草地的主要生态保护功能不同，湖面临高污染风险，除湖子系统调蓄水能力较好的区域外，其他区域农业种植依赖于降水。红枫湖流域可划分为9类生态管控区。【结论】基于协调、权衡关系的分区方法能够保证各类分区生态环境差异的最大化，各分区管理措施差异明显。 |

| Abstract: |
| 【Objective】This paper is to propose a method to optimize ecological space zoning and develop scientific management strategies for watersheds. The focus is on clarifying the synergies and trade-offs among mountains, waters, forests, farmlands, lakes, and grasslands.【Method】The study takes the Hongfeng Lake watershed as a case study. It is a typical watershed consisting of mountains, water, forests, fields, lakes and grasses. Quantitative and qualitative methods were used to calculates synergies and trade-offs between these sub-ecosystems at both basin scale and local scale. The ecological zoning in the watershed was analyzed by considering the synergistic relationships between mountains, waters, forests, farmlands, lakes and grasslands.【Result】The study revealed significant spatial variation in ecological zones within the studied areas. It identified contrasting spatial relationships in the distribution of synergies and trade-offs, particularly between water and other subsystems, as defined by the water intersection line. Key findings include differentiated ecological protection roles of forests and grasslands, high pollution risks facing lakes, and the reliance on rainfall for agriculture outside regions where lakes effectively manage water storage. The watershed was classified into nine ecological control zones, including urban water source protection zones and ecological agricultural zones along the lake and its tributaries. Additionally, mountain areas were designated as ecological industrial development and conservation zones, water source conservation zones, and geo-hazard risk zones. 【Conclusion】By analyzing the coordination and trade-offs among various ecological components, this study ensures the maximization of ecological diversity within each zoning type. The findings highlight the need for tailored management strategies across different zones to address their unique ecological needs and challenges. |
