摘　　要：从地理位置及人为扰动方面考虑，高原湖泊是研究全球气候变化以及其地质成因的最佳对象之一。基于1970~1990年的水文气象资料，对纳木错湖水位进行了同量纲线性分析，得出纳木错湖降雨量、蒸发量及冰川径流等各种因素的影响因子，进而建立了纳木错湖水位变化模型。通过该模型可以较好地模拟高原湖泊水位变化情况，且通过分析可知，纳木错湖存在较大的地下水渗漏，对次级湖泊水位带来一定的影响。In terms of geographical location and artificial disturbance, the plateau lake is one of the best areas for studying the causes of climate change and geological genesis. Through collection of a large number of meteorological data from 1970 to 1990, the impact factors of precipitation, evaporation and glacial runoff were obtained by studying the water level of Nam Co Lake with linear dimension, and then the water level variation model of Nam Co Lake was established. The water level variation of plateau lake can be better simulated by the model, and it is found that significant groundwater seepage exists in the lake, which may in-fluence the water level of secondary lake.
