中文摘要	本文研究了一种基于含水层海水入侵模拟模型(子模型)和作物优化配水模型(子模型)的沿海缺水灌区水资源优化调配耦合模型,用数值方法求解了含水层海水入侵模拟子模型,并首次将基于分解协调的人工鱼群算法应用于作物优化配水的计算,通过地下水抽水量实现了子模型的耦合,利用Visual Basic6.0软件编制了耦合模型的计算程序.将模型应用于威海市节水灌溉示范区,得出其平水年(50%)、一般干旱年(75%)两种水文年型的水资源联合调配方案.结果表明基于分解协调的人工鱼群算法收敛性好,提高了计算速率,较好的解决了作物优化配水大系统中常见的变量维数高、约束方程多等问题;示范区平水年增加有效供水量997.05m~3/hm~2,一般干旱年增加有效供水量863.1m~3/hm~2,能高效利用水资源并能有效控制含水层海水入侵,经济效益和生态效益明显.
英文摘要	A model, coupling the three dimensional mathematical model for seawater intrusion (submodel) arid the optimal model of water utilization for crops(sub-model), is developed for water resource optimal utilization in coastal water-deficient region. The artificial fish school algorithm based on decomposition and coordination method are used to solve the two models. The coupled model is realized by the quantity of pump water. Using Visual Basic 6.0 to program for the coupled model. The coupled model is applied in water saving irrigation region, Weihai city, Shandong province. The irrigation region optimal operation schemes of normal (50%) and dry (75%) years are computed. In the result, the artificial fish school algorithm based on decomposition and coordination method shows its advantages on computing speed, convergence and solving dimension difficulty. The results show that the region can increase 997.05m~3/hm~2 irrigation water in normal year and 863.1m~3/hm~2 in dry year. The results also indicate that the model can improve the efficiency of water utilization, with increases economic and environmental benefits.
