  "abstract": "目的探明滇中城市群不同空间尺度下生态系统服务的时空格局，深度揭示服务间权衡协同关系的尺度依赖效应与非线性演变规律。方法基于InVEST模型、MaxEnt模型及GIS空间分析，对2003—2023年滇中城市群6类关键生态系统服务进行量化评估；综合运用皮尔逊相关分析、双变量空间自相关及生产可能性边界-边际转换率（PPF-MRT）模型，系统解析各服务的时空演变特征、多尺度权衡强度及相变阈值。结果1）2003—2023年，研究区产水量、土壤保持量、粮食供给量与休闲游憩服务增幅均超20%，碳储量与生境质量呈先降后升波动特征；空间上形成外围屏障区主导调节与生产、核心城镇区主导休闲游憩的功能互补格局。2）生态系统服务权衡与协同具有显著尺度依赖性，格网尺度受土地排他性制约呈绝对权衡，县域尺度因空间缓冲效应转化为结构性区间约束，权衡关系未因尺度上推而根本消解。3）PPF-MRT模型精准测度服务转换的非线性边界，格网尺度下碳储量-休闲游憩与土壤保持-产水量分别在跨越阈值X₀=0.235与X₀=0.147后由协同转负向权衡；县域尺度下粮食供给-生境质量在主体区间0.077<X<0.832内呈稳定负向权衡。结论滇中城市群生态系统服务权衡关系具有显著的尺度依赖性，意味着需以非线性相变阈值为基础，构建多尺度嵌套的空间管治策略，统筹微观底线约束与宏观功能协同，以推进喀斯特石漠化地区的生态修复与可持续治理。",
