摘要
通过多途径获取到1958-2010年间相对连续的乌伦古湖水位和矿化度年际系列,对湖泊水位和矿化度的较长年际变化,及空间变化情况进行了分析。结果表明:自1958年以来,乌伦古湖大、小湖水盐变化经历了同步加速萎缩、不同步萎缩和水盐关系紊乱3个显著不同阶段;大湖矿化度进一步均匀化,小湖由淡水系统向微咸水系统转变,湖泊生态劣变趋势加剧。在流域水资源系统先天不足的前提下,长期以来高强度过度利用和水资源的不科学调度管理,是导致乌伦古湖水盐系统变化、紊乱的根本原因所在。
Based on the relatively continuous annual water level and salinity data series（ 1958- 2010） of Ulungur Lake obtained by multiple methods,the longer interannual and spatial changes of water level and salinity have been analyzed. The results show that the water and salt of the Brenda and Jily lakes of Ulungur have experienced three typical stages since 1958,namely,synchronous atrophy period,asynchronous atrophy period and water- salt relations disorder period. The salinity of the Brenda lake has been further homogenized; the fresh water system of the Jily lake is being changed to the brackish water system; and the trend of ecological deterioration of the lake has been aggravated. The root causes of the changes and disorder of the water and salt systems of Ulungur Lake are excessive utilization at high intensity for a long period of time and unscientific scheduling and management of water resources under the condition of congenital water resource deficiency in Ulungur Lake Basin.
