摘　　要：研究目的:以武汉市为例,探索基于“生态质量—生态网络”框架的生态修复区识别方法体系,为国土空间生态保护与修复提供支撑。研究方法:以“本底—功能—结构”框架评估生态质量,利用“生态质量—生态用地”模式构建生态网络,基于“生态源地缓冲区”识别生态修复区。研究结果:(1)武汉市生态质量总体中等偏上,呈现中心城区低、偏远城区高的空间格局,2000—2020年呈现“上升—下降—下降—上升”的趋势,土地覆被变化是其最主要的原因。(2)生态网络格局包括22个陆地源地,面积363.66 km2;20个陆地战略节点,面积9.92 km2;47个水域源地,面积650.25 km2;16个水域战略节点,面积7.95 km2;21条廊道组成陆地廊道网络,长江、汉江和8条主要河流组成水域廊道网络。基于生态网络构建了“两轴一环一带,四楔八水五区”的生态保护与修复空间格局。(3)识别生态修复关键区陆域24个斑块、面积13.96 km2,水域47个斑块、面积111.47 km2;并划分城市森林公园、城市湖泊公园、湿地保护区、水库水源地和山区森林源地5类关键区,分别提出生态修复策略。研究结论:武汉市应以生态保护与修复空间格局为指导,以生态修复关键区为重点,针对不同类型、具有不同生态定位和需求的区域采取不同的生态修复策略。The purpose of this study is to explore the methodological system for identifying ecological restoration areas based on the“ecological quality-ecological network”framework,to support the ecological protection and restoration of territorial space,by taking Wuhan City as a study area.The research methods are to assess ecological quality by using the“background-function-structure”framework,construct an ecological network based on ecological quality and ecological land use,and identify ecological restoration areas based on the ecological source buffer zone.The research results are show that:1)the overall ecological quality in Wuhan City is moderately high,with a spatial distribution shown as lower quality in the central urban areas and higher quality in the peripheral districts.Between 2000 and 2020,it experienced a fluctuating trend of“rising-declining-declining-rising”,primarily driven by the changes in land cover.2)The ecological network pattern includes 22 land source areas covering an area of 363.66 km2;20 land strategic nodes spanning 9.92 km2;47 water source areas with a total area of 650.25 km2;and 16 water strategic nodes comprising 7.95 km2.It also includes 21 land corridors,and water corridors such as the Yangtze River,Han River,and 8 major rivers.Based on the ecological network,the ecological protection and restoration spatial pattern of“two axes,one ring,one belt,four wedges,eight rivers and five districts”has been constructed.3)The key area for ecological restoration has 24 land patches with an area of 13.96 km2 and 47 water patches with an area of 111.47 km2;and the key area is divided into five categories,i.e.,urban forest parks,urban lake parks,wetland protection areas,reservoir water sources and mountain forest sources,with the corresponding ecological restoration strategies are proposed respectively.In conclusion,Wuhan City should be guided by the spatial pattern of ecological protection and restoration,with a focus on key areas of ecological restoration.Different ecological restora
