环京津山水林田湖草多目标跨区联动保护修复模式

河北环京津山水林田湖草生态保护修复试点是国家第一批山水林田湖草生态保护修复试点之一。环京津试点区域位居京畿要地，是京津冀城市群的生态安全屏障。该区域生态系统服务退化，山水林田湖草要素资源约束趋紧，生态修复难度大任务重，联防联控与协同共建机制有待健全。为此，试点实施方案明确了“自然分区-突出问题-绿色奥运”三维导向的修复思路，制定了“指标引导-空间定位-任务聚焦-工程落地”四步推进的实施路径。试点实施2年多来，河北省协同京津全面开展山水林田湖草生态系统保护修复工作，区域生态环境协同治理取得了阶段性成果，形成了以本底层、管理层、政策层、目标层为基本构架，以多要素综合、多部门协作、多渠道保障、多目标优化为核心内容的山水林田湖草“多目标跨区联动”保护修复模式。

Multi-target and inter-area linkage protection and repair mode of mountain-river-forest-farmland-lake-grass around Beijing and Tianjin

The pilot project of ecological protection and restoration of mountain-river-forest-farmland-lake-grass (MRFLG) around Beijing and Tianjin is one of the first pilots of ecological protection and restoration of MRFLG. The pilot area around Beijing and Tianjin is located in the capital vicinity and is an ecological security barrier of the Beijing-Tianjin-Hebei urban agglomeration (BTHUA). The ecosystem service function is degraded, the constraints of MRFLG resources are tight, the ecological restoration is difficult, and the joint prevention and coordination and synergy mechanism needs to be improved in the region. Therefore, the pilot implementation plan clarified the three-dimensional orientation restoring ideas of natural zoning, prominent issues, and green Olympics, and formulated the four-step advancement implementation path of indicator guidance, spatial positioning, mission focus, and project landing. After more than two years of the pilot implementation, Hebei province coordinated with Beijing and Tianjin to carry out the protection and restoration of the MRFLG comprehensively, and the coordinated implementation of the ecological environment has achieved periodical results in BTHUA. It has formed a multi-objective and inter-regional linkage protection restore mode of MRFLG with the bottom layer, management layer, policy layer, and target layer as the basic framework, with multi-factor synthesis, multi-sector collaboration, multi-channel guarantee, and multi-objective optimization as the core content.
