摘　　要：区域生态网络是保护生态安全的基础,生态修复关键区确定及有效诊断是治理与恢复生态系统的关键。以辽西走廊为例,综合生态系统服务功能性、生态环境质量重要性和景观连通性分析,识别生态网络与生态修复关键区域,构建生态安全格局并提出治理优化策略。结果显示:(1)辽西走廊生态环境空间分布差异显著,西部较好,东部与北部较差;(2)识别出66个生态源地、111条最佳生态廊道、11处生态夹点、13处生态障碍点与8处生态断裂区,构成“三环、五区、两干、七支、一屏、多点”的生态安全格局;(3)生态修复关键区由源地、廊道、夹点、障碍点共同组成,根据空间分布特征,划分为生态保护区、生态防护区、生态恢复区、生态控制区与生态发展区,结合相关生态问题提出相应优化策略。研究结果可为辽西区域生态安全保护提供参考,助力生态高质量发展。The regional ecological network serves as the foundation for ecological security protection,and the identification and effective diagnosis of key ecological restoration areas are crucial for managing and restoring ecosystems.Taking the Western Liaoning Corridor as an example,this study integrates ecosystem service functions,the importance of ecological environment quality,and landscape connectivity analysis to identify ecological networks and key ecological restoration areas,establish a sound eco-logical security pattern,and propose regional ecological governance and optimization strategies.The results indicate that:(1)The spatial distribution of the ecological environment in the Western Liaoning Corridor varies significantly,being better in the west and worse in the east and north;(2)66 ecological sources,111 optimal ecological corridors,11 ecological pinpoints,13 ecological obstacles,and 8 ecological fracture zones were identified,forming an ecological security pattern of“three rings,five regions,two branches,seven branches,one screen,and multiple points”;(3)The key areas for ecological restoration include source areas,corridors,pinches,and obstacle points.Based on spatial distribution characteristics,they are categorized into ecological protection areas,ecological restoration areas,ecological control areas,and ecological development areas,with corre-sponding optimization strategies proposed to address relevant ecological issues.The research results can serve as a reference for ecological security protection in Western Liaoning and assist in high-quality ecological development.
