Abstract:

Based on the summarization of annual surface runoff loss processes from 1956 to 2000, and current status of the surface runoff loss mechanisms of the large irrigated areas such as Ningxia in the upper, Guanzhong in the middle and irrigated area in the lower Yellow River, this paper analyzes the characteristics of the structural change in the basin runoff loss of the Yellow River, discusses the concept of the structural adjustment of runoff utilization quantity of the Yellow River, and explains the feasibility of putting it into practice. The analysis of the relationships among water supply, water utilization, water loss and water drainage will have much meaning in balancing supply-demand of water resources and the superior allocation scheme of water resource and so on. In addition, the basic data used in this paper to calculate the surface runoff loss etc. are the same as the data used for survey and assessment of water resources in the Yellow River Basin from 1956 to 2000.

Key words: Yellow River Basin, surface runoff loss, water loss configuration
