| 国土空间生态修复是践行生态文明建设理念的重要措施,而如何精准识别生态修复区域是开展国土空间生态修复事业的难点. 以长株潭都市圈为研究区,将生态退化风险评价与生态安全格局构建相结合,精准识别出生态保育区和生态修复区,并提出国土空间生态保护与修复策略. 结果表明：①研究区生态退化风险整体上呈现出“中高周低”的空间格局；②诊断出源地修复区105.98 km2,廊道修复区643.25 km,踏脚石修复区16.59 km2；③构建了长株潭都市圈“一心一环一屏障”的生态网络空间格局,包括绿心、生态中环和外围生态屏障；④基于识别结果,结合研究区实际情况,提出了具体的国土空间生态保护与修复措施,形成了协同“治理-管理-监督-预警”的跨区域修复机制. 研究成果有助于长株潭都市圈制定和开展国土空间生态修复计划和措施,也可为其它类似地区的生态保护与修复研究提供科学方法. |

| Ecological restoration of territorial space is an important measure to implement the concept of ecological civilization construction, and accurately identifying ecological restoration areas is a difficult point in carrying out the ecological restoration of territorial space. Taking the Chang-Zhu-Tan metropolitan area as the research area； we used methods and models, such as the water balance equation, InVEST model, and circuit theory； combining ecological degradation risk assessment with ecological security pattern construction； accurately identifying the ecological conservation area and ecological restoration area of the ecological source area, ecological corridor, and stepping stone； and proposed strategies for ecological protection and restoration of national land space. The results indicated that： ① The ecological degradation risk in the study area substantially showed a “medium high and low weekly” spatial pattern. ② A total of 74 ecological source areas were identified with a total area of 5 425.21 km2, 170 ecological corridors with a total length of 1 608.26 km, and 78 stepping stones with a total area of 24.35 km2. A source restoration area of 105.98 km2, corridor restoration area of 643.25 km, and stepping stone restoration area of 16.59 km2 were diagnosed. ③ We constructed an ecological network spatial pattern of “one heart, one ring, and one barrier” in the Chang-Zhu-Tan metropolitan area, including the green heart, ecological middle ring, and peripheral ecological barrier. ④ Based on the identification result of ecological restoration of territorial space and combined with the actual situation of the research area, differently oriented ecological protection and restoration measures have been proposed, and a collaborative cross regional restoration mechanism of “governance-management-supervision-early warning” was formed. The research results are helpful for the formulation and implementation of ecological restoration of territorial space plans and measures in the Chang-Zhu-Tan metropolitan area and can also provide scientific methods for ecological protection and restoration research in other similar areas. |
