内容 研究概要:For seeking the origin of water and the hydrologic cycle, we investigated the major ion concentration of inland waters in and around desert area in Xinjiang, NW China. Concentrations of a short-lived radioactive isotope, tritium, two stable isotope species, oxygen-18 and deuterium (D), and isotopic compositions of strontium are also measured. The chemical and isotopic composition of the waters from these areas have regional characteristics which mean that the geological feature of their water-head and drainage areas control the chemistry of inland waters. Hydrogen and oxygen isotope compositions show that river waters are not directly recharged by rain water, but by glacier and/or frozen ground melt, therefore the seasonal variation of isotopic compositions is not so conspicuous as that of precipitation. The results of tritium concentration of waters also suggest that glacier and/or frozen ground melt are important source of water flow of the basins in Xinjiang.
