摘要
根据由气象站和田间试验搜集到的民勤县各灌区1985—2008年间统计数据资料,建立了民勤县典型作物基于机会约束规划的优化灌溉制度模型,利用动态规划方法求解,制定出了几种典型作物在不同水文年的灌溉制度,其节水增产效果显著,并对其用水风险进行了分析。
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 opti tion procedure of typical crops at the level of different hydrological years was formulated by dynamic programming, and the result of saving water and increasing output of optimization significant what＇s more, a risk analysis of water amount was given. mization irriga- the approach of irrigation were
