Conditions of precipitation surface and underground water resources in the Guanzhong area were analyzed.Problems of water resource use such as the low efficiency of traditional irrigation were discussed.A proposition and the measures for construction of a water-saving irrigation zone in the area were presented.It is suggested that construction standards of the water-saving irrigation area must be formulated as soon as possible.A great attention must be paid to saving water in its delivery and improving the ways of irrigation.Also

attentions shouldbe paid to practicing biological saving water

extending the limited irrigation for a sufficient use of water resources

enhancing agronomic measures to save water

extending the soil surface measure to prevent soil water from evaporating

using new water resources and reducing expenses

and expanding the uses of non-convention water resources.These measures are the key to construction of the water-saving irrigation zone

and are the basic measures for sustainable use of water resources in the area.
