摘要 以銀川市为研究区，利用高分遥感和航空影像，通过人工目视解译和精度验证获取银川市2015—2020年土地利用变化矢量数据，定量评价了银川市5年间土地利用时空变化动态特征。结果表明，银川市5年间土地利用变化总面积为16 344.2 hm2，其中建设用地以30%的增加占比发生显著变化，呈现快速增长态势。银川市城镇、农业和生态3类空间的土地利用变化剧烈程度分别为18.0%、5.3%和7.0%，城镇空间是银川市地类变化的热点区，农业和生态空间落实了较为严格的管控制度，变化较小。兴庆区、金凤区和西夏区的综合土地利用动态度分别为69.1%、41.2%和9.9%，土地利用变化剧烈程度分别为11.0%、17.7%和5.0%，金凤区综合土地利用动态度和变化剧烈程度均偏高，需要加强土地节约集约利用水平和优化调控力度，保障城市平稳有序建设和发展。通过土地利用时空变化综合评估与归因分析，为银川市加强国土空间规划管控，科学合理和集约高效利用土地资源，建设生态宜居城市提供参考。

Abstract Taking Yinchuan City as the research area， using high-resolution remote sensing images and aerial images， the land use change vector data of Yinchuan City from 2015 to 2020 was obtained through manual visual interpretation and accuracy verification， and the dynamic characteristics of land use change in Yinchuan City during the five years were quantitatively evaluated. The results showed that the total area of land use change was 16 344.2 hm2 in the past five years in Yinchuan， of which， construction land accounted for a 30% increase， showing a rapid growth trend. The degree of land use change in urban space， agricultural space， and ecological space were 18.0%， 5.3%， and 7.0%， respectively in Yinchuan. Urban space was a hot spot for land use changes. However， the agricultural and ecological spaces have implemented stricter controls， and the changes had been relatively small in Yinchuan City. The comprehensive land use dynamics of Xingqing District， Jinfeng District， and Xixia District were 69.1%， 41.2%， and 9.9%， respectively， and the intensity of land use changes were 11.0%， 17.7%， and 5.0%， respectively. The changes showed that the comprehensive land use dynamics and the intensity of changes in Jinfeng District were both high. It was necessary to strengthen the level of land conservation and intensive use and optimized the control efforts to ensure the stable and orderly construction and development. Through comprehensive assessment and attribution analysis of land use spatio-temporal changed， which provided a reference for Yinchuan City to strengthen territory spatial planning and control， scientifically， intensively and efficiently use land resources， and build an ecologically livable city.
