- 摘要:
- 结合野外实地调查，对新疆奎屯河流域山前河流阶地和山前冲积扇的形态、结构以及时代进行了研究，并对奎屯河流域山前河流阶地和山前冲积扇的发育过程进行了演化。奎屯河山前的阶地可以划分出四级连续的河流阶地。在阶地形成和发育的过程中，由于受到构造运动的影响四级阶地都发生了明显、复杂的变形。奎屯河山前四期冲积扇由南向北呈串珠状发育。北天山的构造活动对奎屯河山前地貌发育起到了至关重要的作用。
- Abstract:
- Based on field survey, the forms, structures and ages of fluvial terraces and alluvial fans of the Kuitun River, as well the evolution processes were studied, and the impacts of neotectonic movements on fluvial geomorphology are discussed in the northern front of the Tianshan Mountains.The Kuitun river has four well developed terraces.Affected by tectonics, the terraces were deformed obviously and complexly.There are four alluvial fans arranged as a string of beads from the south to the north.Tectonic movements took important roll for the evolution of alluvial landforms of the Kuitun River in the northern front of the Tianshan Mountains.
