中文摘要:
      康苏河是新疆乌恰县康苏地区唯一可供饮用、灌溉的淡水河。本研究采集康苏河不同汇流方向的地表水、雪融水及泉水等41件样品,分析其总溶解固体(TDS)、pH值及主要化学成分,通过统计分析、Piper阴阳离子三角图和Gibbs 图等方法对比研究表明,康苏河、库孜拱河水化学类型为HCO-3+SO2- 4Na++Ca2++Mg2+型,硝若布拉克河为SO2-4-Cl-+Na++Ca2+型;雪融水水化学类型为SO2-4+HCO-3-Ca++ Na+ 型;泉水水化学类型为SO2-4+Cl-Na++Ca2+型。河水中主要离子浓度介于雪融水与泉水之间,且接近雪融水浓度,表明地表水更多依靠雪山融水补给。康苏河、库孜拱河、硝若布拉克河的水化学离子组成主要受岩石风化作用和蒸发结晶作用的共同影响,岩石风化作用对硝若布拉克河的水化学离子组成影响更显著,泉水水化学离子组成主要受沉降、水岩作用影响。
英文摘要:
      Kangsu River is the only freshwater river that can be used for drinking and irrigation in Kangsu Town, Wuqia County, Xinjiang Province. The surface water, snow melting water and spring water in different confluent directions of the Kangsu River were collected, and their total dissolved solids (TDS), pH, and major chemical components were analyzed. Through a comparative study of comprehensive statistical analysis, Piper anion-triangle map, and Gibbs diagram shows that rivers in different watersheds have different hydrochemical types. The hydrochemical types of Kangsu River and Kuzigong River are HCO3+SO4-Na+Ca+Mg, the hydrochemical type of Xiaoruobulake River is SO4-Cl+Na+Ca, hydrochemical type of snow melting water is SO4+HCO3—Ca+Na, the hydrochemical type of spring water is SO4+Cl-Na+Ca. The main ion concentration in the river water is between the snow melting water and spring water, and it closes to the snow melting water concentration. It shows that the surface water mainly depends on recharge of snow-capped mountains. The hydrochemical compositions show that, the hydrochemical compositions of the Kangsu River, Kuzigong River, Xiaoruobulake River, are mainly affected by weathering of rocks and evaporation crystallisation, and the effect of rock weathering is more pronounced in the Xiaoruobulake River, the hydrochemical composition of spring water is mainly affected by sedimentation and water-rock interaction.
