[Objective] To construct an optimal water resources allocation model .[Method]This study chose the water resources of the Yellow River for Gansu Province as the research object .The optimal technique of water resources management decision support system was used to construct the model of opti -mal allocation of water resources through years of water supply and demand balance analysis .[Result and conclusion]Model calculation results showed that in the 2020 and forward 2030 time period , water re-sources allocation would be 5.275 billion cubic meter and 6.452 billion cubic meter respectively , inclu-ding a reduction in agricultural water for 280 million cubic meter and 70 million cubic meter compared to their last decade's respectively , and other industry water consumption would increase to some extent .This scheme can meet region's socioeconomic and ecoenvironmental development demands for water resources according to the prediction .%[目的]构建水资源优化配置模型．[方法]以黄河流域向甘肃省可供水资源为研究对象，通过多年供需水量平衡分析，采用水资源管理决策支持系统中的最优化技术，构建水资源优化配置模型．[结果和结论]模型计算结果显示：近期2020年和远期2030年水资源配置分别为52.75和64.52亿m3，其中农业用水较前10年分别减少2.8和0.7亿m3，其他行业用水不同幅度增加．预测该配置方案能满足该地区社会经济与生态环境发展对水资源的要求．
