| 摘 要： | 为了系统地研究黑河流域的水量平衡，该文应用Penman-Monteith模型和波文比公式估算黑河流域的蒸散发量，并结合流域的流量观测与已有的研究成果，首次将流域的大气输送水量与地面水循环结合起来研究分析:黑河流域上空大气水汽输送净收入量约288亿m3；上游山区为多降水中心，成为河流的发源地，降水总量约有141.68亿m3；中下游内陆盆地成为低降水极值中心，降水总量约有55.13亿m3；黑河流域总蒸散量约为195.6亿m3，其中在上游山区蒸散约95.44亿m3的水分，中下游蒸散损失的水量达到100.16亿m3。结合黑河流域水资源量的时空变化情况，从分析内陆河水循环主要环节出发，揭示了黑河流域水循环在山区形成水资源、在中下游内陆盆地散失水资源的特征。

| Abstract: | 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. |
