摘要
我国阿尔泰山、天山、昆仑山与准噶尔盆地和塔里木盆地构成了新疆地貌的基本轮廓.新疆地质构造与气候条件复杂,地貌类型多样,主要可划分为熔岩地貌、冰川地貌、冰缘地貌、流水地貌、黄土地貌、干燥地貌、风成地貌和湖成地貌等类型,具有山系走向与深大断裂方向一致,山地与盆地高差悬殊,山地层状地貌明显,山间盆地多,沙漠面积大,各山地气候地貌垂直分带各异,地貌类型组合呈环状结构等特点.
The Altai Mts., Tianshan Mts., Kunlun Mts., and the basins of Junggar and Tarim found basic outline of Xinjiang Geomorphology.Both the landform and geomorphic typeare complicated because of the complicated geologic structure and climate. According totheir formation, the geomorphology of Xinjiang is divided into following eight kinds:1 lava,2 glacial, 3 periglacial, 4 fluvial, 5 loess, 6 arid, 7 wind-drift, 8 lacustrine. Further classifica-tion gives out 212 kinds, the geomorphic characteristics of Xinjiang are: 1 That the strike of mountain system be the same as direction of deep fracture. 2 That there are great elevation differences between the mountains and the basins. 3 That stepped topography of the mountains is obvious. 4 That desert area is very large. 5 That there is some difference in vertical belt of the geomorphologic action by exogcnic force between the mountain. 6 That there are many intermontane basins. 7 That the geomorphologic structure of types arc girdled
