| Abstract: |
| For the situation of Liangzhou in Wuwei City, agricultural planting structure optimization measures are added to traditional water-saving potential under the premise of food security, industrial demand for raw materials, livestock fodder a
nd so on. The concept of agricultural water-saving potential which is based on structure optimization and its calculation method are proposed. Its calculation process includes reducing irrigation quota, raising irrigation water efficiency
and optimizing planting structure. Liangzhou District was selected as a case study in 2005, the agricultural water saving potential based on structure optimization is 263 million cubic meters, which is 13.3% more than traditional methods, as a result, the agricultural output increased by 604 million yuan and the net income increased by 432 million yuan. |
