摘　　要：为了加强好水川流域农业水资源管理,优化与农业密切相关的作物种植结构,促进水资源优化配置,根据该流域的自然、社会、经济等条件,建立了作物综合效益评价指标体系,并采用多层次决策分析法确定了各指标的权重。基于模糊多目标优化理论建立了该流域作物种植结构的优化模型,对该流域主要作物结构优化进行了计算。结果表明:流域内小麦、玉米、豌豆、胡麻、土豆5种主要作物的最优种植面积为337.33、318.80、71.87、189.87、308.80 hm2。In order to strengthen the water resources management for agricultural, optimize crop planting structure closely related with the agricultural water consumption and, promote the optimal allocation of water resources, according to the natural, social and economic conditions in Haoshuichuan watershed, this study established the index system of integrated crop benefit evaluation, adopting the method of multi-layered decision analysis to determine the indexes weight. Based on the theory of fuzzy multi-objective optimization, the crop planting structure optimization model had been established and calculated. The results show that the optimal crops cultivate area in the basin are wheat 337.33 hm2 , corn 318.80 hm2, peas 71. 87 hm2 , benne 189.87 hm2 and potato 308.80 hm2.
