  "abstract": "目的为应对珠江上游喀斯特地区生态退化、景观破碎化与连通性下降等问题，构建耦合生态系统服务功能与景观格局的生态网络优化框架，为流域生态保护与国土空间治理提供依据。方法以珠江上游为研究区，依托InVEST模型量化水源涵养、土壤保持与固碳释氧三大核心服务功能，结合形态学空间格局分析（MSPA）提取核心景观要素，通过空间叠置筛选生态源地；进而融合多源自然-社会数据构建综合生态阻力面，借助电路理论与Linkage Mapper识别生态廊道、夹点与障碍点，进而提出生态网络优化策略。结果研究共识别优质生态源地29个，总面积4 728.27 km²，主要集聚于东南部山地，与“西北高、东南低”的综合阻力格局形成强烈反差。基于电路理论提取74条生态廊道，总长3 274.82 km，整体呈“东密西疏”的非均衡分布特征；同时识别出23处生态夹点和31处生态障碍点，主要分布于地形收束与人为扰动叠加的关键瓶颈区域。结论喀斯特恶劣基底与人类活动的“双重空间挤压”，致使珠江上游生态网络呈现强烈的空间极化与结构脆弱性。由此确立的“一核、两轴、三区、多点”空间优化蓝图，提出分区管控与靶向修复相结合的差异化策略，为西南喀斯特流域生态安全格局构建与生态韧性提升提供科学支撑。",
