摘　　要：分析三生空间格局演变过程及特征,对优化土地资源配置,促进区域协调发展具有重要意义。以荆州市为研究对象,基于2000-2020年土地利用数据,运用三生空间动态度、转移矩阵、重心迁移模型和景观格局指数等分析工具,对三生空间格局演化特征进行了探讨。结果表明:农业生产空间和水域生态空间构成了荆州市三生空间的主要类型;研究时段内,农业生产空间、其他生态空间面积有所减少,与此同时其他类型的空间均得到了一定的增长;三生空间的演变的主要特征表现为农业生态空间与水域生态空间之间的相互转化,以及农业生产空间向其他类型空间的转移;农村生活空间、林地生态空间、草地生态空间的重心迁移程度较小,其他类型三生空间的重心迁移较为显著;三生空间景观格局总体呈现出破碎化和复杂化的趋势,空间连通性逐渐减弱。城乡建设对农业空间的占用以及湿地保护修复工程的实施是影响荆州市三生空间格局演变的主要因素,建议加强耕地和湿地的保护工作,确保区域粮食安全和生态安全,促进经济社会与生态环境的协调发展。The analysis of the evolution process and characteristics of the production-living-ecological space pattern is of paramount importance for the optimization of land resource allocation and the promotion of coordinated regional development.This study takes Jingzhou City as its focus,leveraging land use data from the years 2000 to 2020.By employing a suite of analytical tools,including the dynamic degree of production-living-ecological space,transfer matrix,center of gravity migration model,and landscape pattern indices,the study provides a comprehensive examination of the evolutionary characteristics of the production-living-ecological space pattern.The results indicate that agricultural production space and aquatic ecological space are the predominant types within the production-livingecological space framework in Jingzhou City.Over the past two decades,there has been a significant reduction in the area of agricultural production space and other ecological spaces,while other types of production-living-ecological space have experienced a certain degree of expansion.The evolution of the production-living-ecological space is primarily characterized by the mutual transformation between agricultural ecological space and aquatic ecological space,as well as the transition of agricultural production space into other types of spaces.The migration of the gravity centers for rural living space,forest ecological space,and grassland ecological space has been relatively minimal,indicating a stable distribution for these particular spaces.In contrast,more pronounced shifts in gravity centers have been observed for other production-living-ecological space types.The landscape pattern of production-living-ecological space exhibits an increasing trend toward fragmentation and complexity,with a concomitant decline in spatial connectivity.The primary drivers identified for the evolution of the production-living-ecological space pattern in Jingzhou City include the encroachment of urban and rural construction on agricultural land and t
