英文摘要Currently, the economic wheat production faces severe challenges due to an increasing number of droughts. In an effort to enhance yields, most arid and semi-arid areas increase the water volume used for irrigation and cultivation of wheat, resulting in an intensified pressure on water resource systems. Therefore, it has become increasingly important to determine the required water volume per unit area in relation to expected wheat performance. However, such an estimation of relevant performance factors has been difficult due to unpredictable water supply capacities and the lack of reliable estimates for the demand of water. The potential crop water productivity (PCWP) defined in this study was comparing with its actual value has which obtained from field measurements based on a new approach of risk quantification. Using this comparison of water use, the management coefficient was estimated, and the production reliability of wheat was calculated. Based on these factors, farms that had competently adapted their management in line with climate change and water availability were selected. The results reveal that only 26 of a total of 666 wheat farms which evaluated for this case study have had reliable crop water productivity and could thus be used as models for other farms. The results showed 100% increasing in CWP with a 27% reducing in hydro-module on these farms, in which case more than 34% will be reduced the groundwater withdrawal. Therefore, the sustainability of groundwater resources would be better, whereas the benefit cost ratio of the whole region and the superior farms has no significant difference. The amount of water that these farms use and the resulting yield can be a suitable reference to determine the expected yield and required water volume per unit area. (C) 2017 Elsevier B.V.
