摘　　要：为重建水文资料缺乏的呼伦湖流域的水文序列,本研究基于长期的气象观测记录,采用彭曼公式估计了湖泊的水面蒸发,并建立一个两参数月水量平衡模型模拟湖周的入流,通过水量平衡计算,模拟了湖泊月水量、水位变化,重建了42年(1961-2002)的呼伦湖区水文序列。模拟的水位变化趋势与实际比较接近,误差较小,模拟精度较好。所重建的42年呼伦湖水文序列,可为该区域的水资源评价管理提供科学依据。Water resource plays an important role in social and economical activity in China, especially in arid or semi-arid northern regions. In the ungauged Hulun Lake Basin, water evaporation was estimated by Penman-Monteith equation by using daily meteorological records at Manzhouli Station, and calibrated with monthly pan evaporation at Alatan＇emole Station. A twoparameters monthly water balance model was developed in the study to reconstruct the hydrological series. 42-years （1961-2002） hydrological series were reconstructed for the Hulun Lake by using the model. Simulated water level is good agreement with the observed annual mean data. The estimation of water resources is reliable, which can provide solid base for wise management of water resources in Hulun Lake.
