In this paper, to study the water balance of Heihe river basin, evapotranspiration of the upper, middle and lower reaches of Heihe river were estimated and analyzed by use of Penman-Monteith model and Bowen ratio formula. Furthermore, the atmospheric moisture transportation and precipitation were analyzed. The net amount of atmospheric moisture transportation was about 2.88×1010 m3 over Heihe river basin. The upper reaches of Heihe river was precipitation center, where the total precipitation was about 1.416 8×1010 m3, and became the source of the river. In the middle and lower reaches, the inland basin became extremely low precipitation center, and the total precipitation was 5.513×109 m3. In the Heihe river basin, the total evapotranspiration was about 1.956×1010 m3, the total evapotranspiration was about 9.544×109 m3 in the upper reaches, and the total was about 1.001 6×1010 m3 in the middle and lower reaches. Referred to the spatial and temporal change characteristics of water resources in Heihe river, the features of the formation of water resources in mountain area and the scatter and disappear of water resources in the inland basin were revealed mainly through analysis on key links in the water cycle of the interior region.
