| 摘 要： | 通过对新疆且末几克里阔勒地区河流阶地的地貌、沉积特征及年龄测定,分析了该地区河流阶地形成的时代,反演了该地区4.45±0.35× 104a以来的隆升历史.结果表明,44.5 Ka以来的历史进程中地壳的隆升速率极大,大大高于目前青藏高原整体隆升2 mm/a的水平;形成的多级阶地表明该区的隆升存在明显的阶段性、间歇性和差异性,其隆升速率具有从快逐渐变慢的总体趋势.

| Abstract: | By study the geomorphology, sedimentary characteristic and determine the age of fiver terrace in Jikelikuole area, the formation age of fiver terraces are analyzed, the uplift process in this area sine 4.45＋0.35 × 104 a are reconstructed. The results indicate that a much higher uplift rate （ 〉2 mm/a） existed in the Tibetan Plateau. The multi-stages terraces suggest that the uplift rates of the study area shows a gradually slow trend since about 4.45×104 a. |
