中文摘要	内蒙古高原地处我国北方半干旱与干旱气候区，经度跨度大，由东向西气候呈现半干旱区向干旱区过渡特征。区内湖泊多属内陆型湖泊，湖泊水化学特征受地理位置和气候环境影响显著。文章在空间上从东向西依次选择呼伦湖、达里湖和乌梁素海为研究对象，通过对不同气候区域和不同类型的湖泊水体中主要离子组成进行分析对比研究，揭示区域内湖泊水化学特征及其控制因素。结果表明，内蒙古高原区内湖泊水化学类型单一，阳离子以Na~+主导，阴离子以Cl~-主导，但各湖泊水体中主要离子质量浓度差异较大。呼伦湖、达里湖和乌梁素海3个湖泊Na~+分别占其阳离子摩尔总数的76.6%、97.2%和66.0%；Cl~-分别占其阴离子摩尔总数的49.6%、55.5%和45.2%。湖泊水体中Na~+和SO_4~(2-)、Cl~-的变异系数相对较小，在水体中质量浓度相对稳定。借助Piper三角图，分析出呼伦湖和乌梁素海阴离子分布在SO_4~(2-)-Cl~-线上，阳离子分布在Na~++K~+线上；达里湖的阴离子分布在HCO_3~--Cl~-线上，阳离子分布在Na~++K~+线上，说明区内湖泊受蒸发结晶和岩石风化共同作用影响。湖泊水体中主要离子质量浓度的空间变化特征受径流，补排关系的影响，结合Gibbs模型图进一步说明了3个湖泊受蒸发浓缩作用和人类活动影响。湖泊水化学特征的研究，对于保护区域内湖泊环境具有重要意义。
英文摘要	Inner Mongolia plateau is located in the semi-arid and arid climate zone of northern China. The climate exhibits both semi-arid and arid characteristics as it spans across longitudes from East to West. Lakes in the region are mostly inland lakes. Their water chemistry characteristics are greatly influenced by geographical and climate. Three lakes, Hulun Lake, Dali Lake and Ulansuhai Lake, were analyzed for their main ions and the discrepancies, the chemical characteristics of the water, and their control factors. The results showed that the water chemical type, cation by Na~+ leading and anion by Cl~- leading, was single by the geographical and climate. However, the main ions content was very different in these lakes. The percent of Na~+ in the total number of mole of cationic was 76.6%, 97.2% and 66.0%, while the percent of Cl~- in the total number of mole of anion was 49.6%, 55.5% and 45.2%, respectively for three lakes. The coefficient of variation of Na~+ and SO_4~(2-), Cl~- was relatively low, it showed the ion content was stable in the water. Based on the Piper triangle chart analyzed ions consist, the anion distributed in the line of SO_4~(2-)-Cl~- and the cation in the line of Na~++K~+ in Hulun lake and Ulansuhai Lake. But the anion was in the line of HCO_3~--Cl~- and the cation in the line of Na~++K~+ in Dali Lake. It shows that the water chemistry characteristics are affected by evaporation and crystallization and rock weathering. The spatial changes of the content of the main ions are also affected by the relationship between runoff and drainage, and are combined with the Gibbs model to further explain the different degree of human activity for these three typical lakes. Researching the lakes’ chemistry characteristics has a great significance for protecting lakes’ environment.
