采用后差分GPS方法对珠穆朗玛峰北坡绒布河谷中时期的冰碛地貌进行实地测量与研究,结合该河谷数值年代,得到时间序列上关于各期次冰碛地貌终碛垄的平面面积、表面面积、体积等参数:基龙寺终碛平面面积、表面面积以及体积分别为1.53×106m2、1.90×106m2和1.98×108m3;绒布寺终碛为1.03×106m2、1.24×106m2和0.82×108m3;绒布德新冰期终碛为1.72×106m2、2.0×106m2和1.98×108m3;小冰期终碛及现代表碛为2.43×106m2、2.60×106m2和1.69×108m3.对比分析认为:河谷地形差异是控制绒布河谷冰碛地貌表面形态的主要因素,冰碛地貌形成过程中冰川退缩方式以及形成以后所遭受的流水切割、搬运等外力作用是影响冰碛垄规模大小差异的基本原因.受局地小气候差异影响,同期次侧碛表现出形态特征的不对称性:新冰期东坡侧碛坡度值大于西坡侧碛,前者为30.7°～46°,后者为30.7°～37.9°,另外在东坡侧碛发育有冰碛土柱,西坡侧碛未见分布. Using post-differential GPS method to field survey and research on the moraine during the mid-erg ravine of the northern slope of Mount Qomolangma, combined with the numerical age of the valley, the time series of moraine ridge moraine ridge area, surface area , Volume and other parameters: Jiarong final moraine flat area, surface area and volume were 1.53 × 106m2, 1.90 × 106m2 and 1.98 × 108m3; Rongbukisi final moraine is 1.03 × 106m2, 1.24 × 106m2 and 0.82 × 108m3; In the late glacial period, the end moraines are 1.72 × 106m2, 2.0 × 106m2 and 1.98 × 108m3 respectively; the final moraine and the modern moraines in the Little Ice Age are 2.43 × 106m2, 2.60 × 106m2 and 1.69 × 108m3, respectively. The comparative analysis shows that: The main reason for the surface morphology of moraine in the valley, the retreat of glaciers during the formation of the moraine landscape and the external forces such as the cutting and handling of flowing water suffered after the formation are the basic factors that affect the size of the moraine ridge. In the same period, the secondary moraine showed morphological asymmetry: the value of lateral moraine on the east slope of the new glaciation period is greater than that of the side moraine on the western slope, with the former ranging from 30.7 ° to 46 ° and the latter from 30.7 ° to 37.9 °. In addition, Lateral moraine moraine soil column are developed, the western slope of lateral moraine and no distribution.
