Agricultural proportion of Ordos City as high as 70%,large water intake with low economic contribution is the main reason for the low comprehensive water efficiency. Implement the rigid constraint system of water resources and promote the refined managementof water resources in Ordos City, the core lies in the agricultural further-up water saving and control of water use. According to the water resources conditions and the current situation of agricultural water use of Ordos City, the coordination relationship and characteristics of water resources and agricultural development was analyzed, and the agricultural water use indexes, efficiency control indexes and development scale in different regions reflecting the high-quality economic and social development and the spatial balance of water resources were proposed. By controlling the scale, structure and water consumption,under the condition of ensuring the key objectives, implement agricultural water saving and efficiency, optimize water allocation and improve water efficiency, so as to ensure the ecological civilization construction and high-quality development of Ordos city.
