摘　　要：新疆巴音郭楞蒙古自治州境内的博斯腾湖近年来水位达到了有史记载以来的最高值。通过还原计算得出以下结论文 :(1)天然状态下博斯腾湖水位通常在 10 4 7.5～ 10 4 8.5m之间变化 ,除非特大年径流量 (5 0～ 10 0年一遇 )水位难以超过 10 4 9.0 0m。 (2 )博斯腾湖死库容水位为 10 4 7.2 0m。 (3) 2 0 0 2年博斯腾湖水位超过 10 4 9m完全是人为造成的。 (4 )现在孔雀河径流量年际变化、年内变化都大于天然状态下。The Bosten Lake is located in Bayingolin Mongol Autonomous Prefecture, Xinjiang, its water level is currently up to the highest value since the historical records, and is extensively paid a great attention to. It is very necessary to restore the inflow of the Bosten Lake so as to research the climate change, water resources, glacial resources, reduction and enlargement of the oases in the Tarim Basin, and the change of the ecological environment in the Bosten Lake region since recent hundred years. After estimating, following conclusions can be obtained: (1) Under the natural conditions, the water level of the Bosten Lake varies in a range of 1047.5m^1048.5m, and it seldom exceeds 1049.0 m except the exceptional high annual inflow occurring once every 50~100 years. (2) The water level of dead storage capacity of the Bosten Lake is 1047.2 m. (3) The water level of the Bosten Lake was higher than 1049 m in 2002, which was completely caused by artificial factors. (4) The current change of the annual and seasonal runoff volumes of the Kongque River is greater than that under the natural conditions.
