摘　　要：对滇中城市群生境质量及影响因素,通过耦合斑块生成土地利用模拟模型和生态系统服务与权衡综合评价模型,模拟不同情景下2030-2050年土地利用变化,探究生境质量的时空演变与空间相关性.结果表明,未来3种情景下,土地利用变化呈现不同趋势,差异明显;自然发展情景和耕地保护情景下生境质量均值持续降低,生态保护情景生境质量均值上涨,改善效果显著;滇中城市群生境质量在县域空间上存在相关性,生境质量“热点”主要聚集在研究区西部,分布分散且面积不断缩减,“冷点”以经济较为发达的中部地区为核心区域,呈现扩张趋势.Research was conducted on the habitat quality and influencing factors of the Central Yunnan Urban Agglomeration with coupling the patch land use simulation model and the integrated valuation of ecosystem services and tradeoffs model,land use changes in different scenarios from 2030 to 2050 simulated,and the spatiotemporal evolution and spatial correlation of habitat quality explored.The results indicated that,under three future scenarios,land use change would show different trends and significant differences;the average habitat quality under natural development and farmland protection scenarios continues to decrease,while the average habitat quality under ecological protection scenarios increases,resulting in significant improvement effects;there was a correlation between the habitat quality of the Central Yunnan Urban Agglomeration in the county space.The"hot spots"of habitat quality mainly gathered in the western part of the research area,with scattered distribution and continuous reduction of areas.The"cold spots"were centered in the economically developed central region,showing an expansion trend.
