摘　　要：兰州—民和盆地恐龙足印化石及其赋存层位的特征表明，恐龙生息与早白垩世沉积环境和构造作用关系密切。盆地扩张时期出现的湖沼环境和构造稳定时期是恐龙生活的最佳时期和场所。 The characteristics of dinosaur footprint fossils and their occurrence horizon in the Lanzhou-Minhe basin indicate that the dwelling of dinosaurs was closely related to the Early Cretaceous sedimentary environment and tectonism.The basin extension stage and tectonic stability stage were the optimal stages for dinosaur dwelling and the lacustrine-swampy environment was the optimal locus for dinosaur dwelling．

关 键 词：恐龙足印化石 沉积环境 构造作用 赋有层位 兰州-民和盆地
