摘要:
      生态修复关键区域划定是落实生态文明建设的重点,通过落实生态修复关键区域、强化生态管控措施来提升生物多样性,能有效缓解区域生态与经济发展不平衡的矛盾。以四川攀枝花为例,基于InVEST模型分析生态本底特征,利用MSPA、Conefor、MCR等模型构建生态网络,结合市域国土空间生态修复规划,综合划定生态修复关键区域,从乡镇域角度落实生态分区。结果表明:2002—2022年,攀枝花16.6%的土地发生流转,主要为森林、农田、草原、灌木间,分别为94.08%、93.93%、92.54%、93.77%,生境质量基本稳定,不变的占比最大;构建的生态网络呈“一屏、多廊、多点”的分布特点,识别生态源地8个(面积为3 536.8 km2),筛选出生态廊道28条,其中重要廊道10条、一般廊道18条;基于市域内乡镇尺度综合划定生态修复关键区域,叠加优先保护区22个、重点管控区32个、一般管控区6个等生态修复重点任务。构建了镇域尺度生态修复关键区域及重点任务分区管控体系,探讨了与国土空间规划的衔接,强化了生态修复与空间治理,可为促进市域可持续发展提供指导。

Abstract:
      The identification of key areas for ecological restoration is pivotal for advancing ecological civilization. Implementing restoration in these key zones and enhancing ecological regulation can effectively mitigate the imbalance between regional ecological conservation and economic development while promoting biodiversity. Taking Panzhihua City in Sichuan Province as a case study, this research analyzed its fundamental ecological characteristics using the InVEST model and constructed an ecological network by integrating the MSPA, Conefor, and MCR models. In alignment with the city′s territorial spatial planning for ecological restoration, key areas for ecological restoration were comprehensively delineated and implemented at the township level. The results indicate that from 2002 to 2022, 16.6% of the land in Panzhihua underwent type conversion, primarily among forest, farmland, grassland, and shrubland. The proportions of these land types that remained unchanged were the highest, at 94.08%, 93.93%, 92.54%, and 93.77% respectively, suggesting overall stable habitat quality. The constructed ecological network exhibits a spatial pattern characterized by ″One Shield, Multiple Corridors, and Multiple Nodes.″ Eight ecological source areas were identified, covering a total area of 3,536.8 km2. Twenty eight ecological corridors were extracted, including 10 important and 18 general corridors. Based on a comprehensive township-level delineation, key ecological restoration areas were overlaid with specific restoration priorities: 22 priority protection zones, 32 key regulation zones, and 6 general regulation zones. This study innovatively establishes a zoning control system for key ecological restoration areas and tasks at the township scale, explores its integration with territorial spatial planning, strengthens ecological restoration and spatial governance, and can provide guidance for promoting sustainable urban development.
