| Abstract: | According to the statistical data from 1985 to 2008 of weather station and field experiments in Minqin county's different irrigation areas,the optimization irrigation procedure model based on the chance-constrained programming(CCP) of the main crops were established.As the result,the optimization irrigation procedure of typical crops at the level of different hydrological years was formulated by the approach of dynamic programming,and the result of saving water and increasing output of optimization irrigation were significant;what's more,a risk analysis of water amount was given. |
| Keywords: | optimization irrigation procedure chance-constrained programming dynamic programming risk analysis |
