The dynamic alterations in land utilization patterns within swiftly urbanizing regions significantly influence the ecological environmental quality. Investigating these land use transformations and their implications for ecological integrity can furnish essential theoretical underpinnings and a foundation for decision-making aimed at fostering sustainable and high-quality growth in rapidly urbanizing areas. Anhui Province was chosen as the research locale， with CLCD data （1990-2020） employed to delineate land use modifications. Concurrently， a remote sensing ecological index （RSEI） was developed utilizing MODIS remote sensing satellite data to examine the interplay between land use transitions and ecological environmental quality responses during the period of accelerated urban expansion from 2000 to 2020. The findings indicate that： ① Amidst rapid urbanization， the expanse of construction land in the Anhui Province exhibited an ascending trajectory over the three-decade interval from 1990 to 2020， with the land use transformation schema predominantly marked by early-stage and late-stage alterations. The composite index of land use intensity across various cities manifested a declining trend. ② The overall ecological environmental quality in the Anhui Province progressively enhanced， with the extent of the ecological enhancement zone surpassing that of the ecological deterioration zone. ③ The enhancement or deterioration of ecological environmental quality was intimately correlated with variations in regional land use categories， demonstrating pronounced spatial heterogeneity. ④ The outcomes of single-factor analysis revealed that land use modifications in the Anhui Province were predominantly swayed by socio-economic dynamics. Interactive factor analysis suggested that the synergy between natural and socio-economic factors yielded effects of superposition or mutual reinforcement. This study underscores that a judicious realignment of land use structures is instrumental in preserving or even enhancing regional ecological environmental quality. The prudent exploitation and utilization of land resources should weigh both natural and socio-economic factors， with particular emphasis on the pivotal role of socio-economic factors in the metamorphosis and evolution of land use.
快速城市化地区土地利用模式的动态变化对生态环境质量有重大影响。研究这些土地利用变化及其对生态完整性的影响，可为快速城市化地区实现可持续高质量发展的决策提供重要的理论依据和基础。选取安徽省作为研究区域，利用CLCD数据（1990 - 2020年）描绘土地利用变化。同时，利用MODIS遥感卫星数据构建遥感生态指数（RSEI），以研究2000 - 2020年加速城市扩张期间土地利用变化与生态环境质量响应之间的相互作用。研究结果表明：①在快速城市化进程中，安徽省建设用地面积在1990 - 2020年的三十年期间呈上升趋势，土地利用变化模式主要以早期和后期变化为特征。各城市土地利用强度综合指数呈下降趋势。②安徽省整体生态环境质量逐步提高，生态改善区面积超过生态恶化区。③生态环境质量的改善或恶化与区域土地利用类型的变化密切相关，呈现出明显的空间异质性。④单因素分析结果表明，安徽省土地利用变化主要受社会经济动态影响。交互因素分析表明，自然因素与社会经济因素的协同作用产生叠加或相互强化效应。本研究强调，合理调整土地利用结构有助于保护甚至提高区域生态环境质量。土地资源的合理开发利用应兼顾自然和社会经济因素，尤其要重视社会经济因素在土地利用演变中的关键作用。
