摘　　要：平衡土地资源利用与环境保护之间的矛盾在城市化快速发展进程中尤为重要。本文选取武汉市2000-2020年的土地利用数据,基于“三生”功能的概念对土地利用类型进行了重新分类,通过土地利用转移矩阵、生态环境质量指数、土地利用转型的生态贡献率等方法,分析了区域土地利用的转型的时空演变特征及其对生态环境的影响。研究发现:研究区域内不同土地类型的时空演变较为稳定。空间上,生产用地主要分布在中心城区外的大部分地区;生活用地主要集中在中心城区内;生态用地主要集中在区域北部,水域生态用地错落分布在整个研究区内。时间变化上,生产用地减少,生态用地先增后减,生活用地持续增长。区域整体生态环境质量指数值逐年下降,其空间分布与土地利用分布关联性明显,郊区明显高于中心城区,呈现中间低,四周高的空间格局,质量较低的区域由中心城区向外扩张。研究区域内不同土地利用类型间的转换对生态环境的影响差异性明显。It's crucial to balance the contradiction between the land resource utilization and environmental protection during the rapid process of urbanization.Selecting the land use data from 2000 to 2020 in Wuhan City the types of land use are reclassified based on the functions of production-living-ecology.And using land use transfer matrices ecological quality indices and ecological contribution rates the spatial-temporal evolution of land use and its ecological impacts are analyzed.The findings reveal that the spatial-temporal evolution for different land types is relatively stable.Spatially production land is primarily located in areas outside the central urban zone living land is concentrated within the central area and ecological land is mainly located in the northern region with water bodies dispersing throughout the research area.Temporally production land decreased ecological land initially increased and then declined while living land was consistently growing the overall ecological quality index declined annually showing a clear spatial correlation with land use distribution and suburban areas was significantly higher quality than that of the central urban area characterized by a low center and higher peripheries the ecological impacts of transitions between different land use types varied significantly.
