摘要(Abstract)：

针对湖北省土地利用碳排放的时空演变特征与驱动机制问题，基于2000—2020年土地利用、经济社会及能源等数据，综合运用碳排放测算、空间自相关分析与LMDI分解模型，开展省、市双尺度分析。结果表明：(1)研究期内碳排放总量显著增长，由2 861.70万吨增至7 364.86万吨，建设用地与耕地为主要碳源，林草地等发挥碳汇作用；(2)空间格局由单一“洼地”向“核心集群+停滞洼地”演变，显现武汉都市圈的辐射极化效应；(3)LMDI分解结果表明，经济发展水平(贡献率347.66%)与建设用地规模(94.65%)是主要正向驱动因子，能源消费强度(-236.03%)等则呈抑制效应。本研究为差异化碳减排策略，协同推进经济发展与生态保护提供了技术参考。
