摘要(Abstract)：

针对目前众多学者主要针对夏季热环境进行研究,分析方法相对单一,且融合地理探测器等多种方法针对不同季节相关分析研究相对较少的问题,该文基于2017—2018年Landsat8遥感数据,反演济南市中心城区四季的地表温度,综合运用景观格局指数法和剖面法分析不同季节热环境空间分布变化;利用相关性分析方法和地理探测器模型针对地表遥感指标和热环境进行相关性和影响力研究。结果表明:济南市中心城区除冬季,地表温度分布东高西低,与自然地表、工业生产、人口活动等区位要素关联密切;气温骤降与骤增导致温度斑块割裂、聚合;水体、水汽与建筑的交互作用对春、夏、秋季的城市热环境影响最大,水体与不透水面(交互因子:0.392 952)对冬季热环境交互影响最大;城市热环境的空间分异特征受多因子影响,其中植被与水体(交互因子:0.379 927)、植被与水汽(交互因子:0.380 707)协同降温效应最优,建筑与植被(交互因子:0.278 922)协同保温效应最优。
