| 人类对自然资源的过度开发利用使生态系统承受着巨大压力，开展生态保护修复成为改善生态系统质量、维护生态安全的重要手段，科学识别生态保护重点区域成为重要议题。以南水北调东线江苏湖网地区为研究区，运用InVEST模型对该区域水源涵养、水质净化、气候调节、生境维持4项生态功能指标进行量化评估，并对评估结果进行空间叠加分析，划分重要生态功能区，将生态功能高值区作为生态保护重点区域。结果表明，生态保护重点区域集中于沿江调水源头区域、主要湖荡及丘陵森林岗区，并从保障水生态安全的角度提出针对性生态保护修复策略。 |

| Abstract: |
| The excessive exploitation and utilization of natural resources by humans have placed enormous pressure on ecosystems. Implementing ecological conservation and restoration has thus become a crucial means of improving ecosystem quality and safeguarding ecological security, making the scientific identification of key ecological conservation areas a significant issue. This study focuses on the lake-network region of Jiangsu along the eastern route of the South-to-North Water Diversion Project. The InVEST model was applied to conduct a quantitative assessment of four key ecosystem service indicators within the region: water conservation, water purification, climate regulation, and habitat maintenance. A spatial overlay analysis was performed on the assessment results to delineate important ecological functional zones, with areas exhibiting high ecological service values identified as key ecological conservation areas. The results indicate that these key areas are primarily concentrated in the water diversion source areas along the Yangtze River, the major lake and marsh regions, and the hilly forest uplands. From the perspective of ensuring aquatic ecological security, targeted ecological conservation and restoration strategies are proposed. |
