The authors attempted to describe structure of surface water use in the Yellow River Basin of China, whose situation was difficult to be understood with a lack of actual data, in directly comparing structure of water resource demand and supply estimated by Onishi et al. (2006) and structure of ground water use estimated by Ichinose et al. (2009) in the each region. 35 municipalities which were almost included in the Yellow River Basin were picked up and they were classified into 12 small catchments in focusing on the geographical location and the similarity of shape of structure of water resource demand and supply (expressed as bar graphs). In the upstream areas surface water is mainly used and share of agricultural use is small, therefore, seasonal variability of ground water use is small. On the other hand, in the middle stream and the downstream areas share of ground water is large and share of agricultural use is large, therefore, seasonal variability of ground water use is large. Especially these characters are obvious in the Loess Plateau. In addition, surface water is mainly used again in the most downstream areas.
