摘　　要：选取处于黄土高原北部水蚀风蚀交错地带的六道沟流域为研究区,基于水平衡方程确定了陕北小流域水资源组成结构的各个分量。通过对水文数据和径流计算结果的分析,推求了流域水量收支的各个成分。考虑到人为因素的影响,居民的生活用水量和农业灌溉用水量因素被加入到水平衡公式中。结果表明,年蒸发量和径流量分别占年总来水量的74.5%和21.5%,年蓄水量变化接近于0,居民的生活用水量和灌溉用水量分别占年总来水量的2.8%和1.2%。研究结果可为水资源相对缺乏的黄土高原北部地区的水资源可持续开发和利用提供基础数据。The objective of this study was to estimate each component of water resources based on water budget formula for a small basin in Northern Shaanxi Province. Liudaogou basin, which is located at wind- water erosion crisscross region in the Northern Loess Plateau, was chosen as the study area. Each component of the annual water budget was estimated through analysis of observed hydrological data and numerical result of surface runoff. Daily water consumption and irrigation water were added into the water budget in order to consider the contribution of human activity. The results indicate that evapotranspiration, runoff, change of water storage accounted for 74.5%, 21.5%, and 0% of the total water budget, respectively, and daily water consumption and irrigation water accounted for 2. 8% and 1. 2%, respectively. The results of this study could provide a basis for sustainable water development and utilization in Northern Loess Plateau, where water resources are extremely limited.
