1997-05在珠峰地区绒布冰川采集的4类水样(表层雪、湖水、河水和泉水)的实测资料表明,本区各类水体都呈碱性,pH值的大小顺序为:湖水>河水>表层雪.河水和湖水的阴离子以SO2-4为最大,而表层雪样品以Cl-最大;阳离子含量基本上以Ca2+为主.SO2-4、Ca2+、F-、Mg2+和pH值都与矿化度有较好的相关关系,随矿化度升高而增大.样品的电导率和Ca2+随着海拔的上升呈下降趋势:其中河水的电导率、F-、Ca2+、矿化度、SO2-4和Mg2+与海拔高度都有较好的相关关系,随着海拔高度上升而降低.
The data of 4 types of water samples (surface snow, lake water, river water and spring water) collected in the Rongfeng glacier in Mount Everest showed that all the water bodies in this area were alkaline, and the order of pH value was: lake water> river water > Surface snow. The anions of river water and lake water have the largest SO2-4, while the surface snow samples have the largest Cl-; the cation content is basically Ca2 +. SO2-4, Ca2 +, F-, Mg2 + and pH have a good correlation with the degree of salinity, with the increase of salinity. The conductivity and Ca2 + of the samples showed a decreasing trend with the elevation of the sea surface. Among them, the conductivity, F-, Ca2 +, salinity, SO2-4 and Mg2 + in river water had a good correlation with altitude, Rise and decrease.
