摘要:
生态保护红线划定是保障国土空间生态安全的重要举措,对保持生态系统的完整性,实现可持续发展具有重要意义.本文基于生态系统服务功能和生态敏感性对杞麓湖流域进行生态安全格局体系的构建,并开展精细化的生态保护红线划定研究,并进一步结合无人机航拍影像及实地调研成果,构建管控路径.得到结论:(1)水源涵养、水土保持、生物多样性、洪水调蓄重要性评价中的极重要区域叠加得到生态系统服务功能极重要区.者湾河、长沙河、大沙河及沟谷密度较大的山区敏感性最高,坝区整体生态敏感性较高.(2)一级生态保护红线范围包括生态极重要区域、生态极敏感区域及湖泊岸线、水库.二级生态保护红线范围包括环湖生态缓冲区、山区林地生态缓冲区及以河流为主的生态廊道.三级生态保护红线范围为生态协调区,土地覆盖以农田为主.(3)一级生态保护红线范围内的生态极敏感区应采取相关生态修复技术进行生态功能的保护.二级生态保护红线范围以生态保护为重点,保持该区域的生态环境质量.三级生态保护红线范围通过生态修复进行整体优化,提高生态环境承载能力.

Abstract:
Demarcation of ecological protection red line is an important measure to ensure the ecological security. It is conducive to maintain the integrity of the ecosystem and achieving the sustainable development. Based on the ecosystem function and ecological sensitivity, an ecological security pattern was constructed for Qilu Lake watershed. This paper demarcates and administers the ecological protection red line. We revealed that:(1) The extremely important regions of sub-elements are superimposed to obtain the extremely important regions of ecosystem function. Zhewan River, Changsha River, Dasha River and mountainous areas have the highest ecological sensitivity, the dam area has higher ecological sensitivity. (2) The red line of first-level ecological protection covers areas of extremely important and sensitive ecology, lake shorelines and reservoirs. The red line of secondary ecological protection covers the ecological buffer zone around the lake, the ecological buffer zone in mountainous areas and the ecological corridor dominated by rivers. The three-level ecological protection red line covers the ecological coordination area, mainly farmland. (3) Ecological restoration should be adopted to protect the ecological functions of the extremely sensitive areas within the red line of first-level ecological protection. The red line for secondary ecological protection focuses on ecological protection to maintain the ecological quality of the region. Overall optimization of the three-level ecological protection red line should be carried out to improve the carrying capacity of the ecological environment.
Key words:  Demarcation of ecological protection red line  administration of ecological protection red line  ecological security pattern  national spatial planning  Qilu Lake watershed
