Abstract: The agricultural and pasturing interlaced zone in Gansu, Ningxia, Inner Mongolia and Shaanxi is arid, where the Yellow River is the only water source passing through this area. The river runoff has been excessively developed, which has brought out a series of severe environmental problems. Although there is South Water Diverting into North Project, the water diverted into the Yellow River mainly meet the need of adjusting the social economical structure and protecting the eco-environment in the river basin except 2×10⁸ m³ water for the agricultural use within Lanzhou-Hekou section. Obviously, economizing water is obligatory in the agricultural and pasturing interlaced zone. As for the several irrigation regions in the interlaced zone that pumping the Yellow River water, some problems resulting in water loss must be resolved as soon as possible:stress developing and despise economizing, stress skeleton and despise supporting project, and stress engineering and despise management.

Key words: agricultural and pasturing interlaced zone, water resource, economizing
