Research on Hydrogeochemistry in Northern Plain of the Urumqi River Basin, Xinjiang
摘要
Abstract
The Urumqi River basin is one of the typical inland basins in arid northwestern China, and also the focus area of regional hydrogeological research. The soil salinization problem exists in the northern plain of the river basin. The evolution of the chemical composition of groundwater has important significance for deepening the study of soil salinization, rational utilization and protection of water resources. Hydrogeochemistry and environmental isotope in northern plain of the Urumqi River basin were analyzed according to the method of some tracers, such as the anions, cations, and environmental isotope, in combination with the geological background. The authors hold that there extensively exist dissolved evaporates of surface water in northern plain, which are related to the increasingly arid climate since Late Holocene (B.P. 4000 years). Three types of groundwater in the area were distinguished: present water (21~65 m in depth) from infiltration recharge of the Urumqi River, water of Late Holocene (179~259 m in depth) from the precipitation infiltration, and water of Late Pleistocene starting with the last glacial period (depth: ~353 m) also from the precipitation infiltration.关键词
