中文摘要论述了长江之源各拉丹冬峰东坡的尕日曲流域冈加曲巴冰川和水晶矿冰川冰、雪、水样品中的pH值、总碱度、总硬度、矿化度,以及K+,Na+,Ca(2+),Mg(2+)和Cl-,SiO2等可溶性离子的含量,同时讨论了其水化学组成类型.
英文摘要 A joint glacial expedition and observation between China and German in Geladandong region (aft. 6 621m) at the headwater of the Changjiang River were carried out in summer of 1989.Some geochemical features about glacial ice,snow and water in this area were presented.The data,which sampled from the Kangkyagqubs Glacier and Shuijingkuang Glacier during the expedition in 1989, showed as follows: all kinds of the glacier ice, snow and water belong to neutral,soft and fresh,as well as high quality water. The mineraliration values have relations with sample depositing time. Their deposit time are more new, the mineralization values are smaller. The mineralizations of snow are lower than 1.00mg/L which also are lower than that of West Kuulun Mountains and Southeast Xizang,as well as Hengduan Mountains former belonging to continental glacial region later being monsoon maritime type.As for the concentration or hydrochemical type among canons Ca2+ is dominant and among anions HCO3- is dominant for all samples. The single Ca2+-hydrochemical type is dominanted in all of the new snow or firn deposited in recent years. It is very interesting that pH in all of the snow and firn deposited in recent years are lower than 7.00 with some lower than 6. 50 and lowest reached down to 6. 24 appearing as weakly acidity pollution tendecy. To say that the pollution from modern industrialization has affected into the center of Qinghai-Xizang Plateau.
