摘　　要：依据2年的水稻水分生产函数专项试验和淠史杭灌区试验总站历年试验统计资料,结合面上调查和室内理论分析计算,建立了适合淠史杭灌区水稻的“作物—水模型”,确定了模型的结构形式和参数取值,在此基础上建立了水稻优化灌溉制度数学模型,并采用动态规划方法求出不同水文年型以产量为目标的优化灌溉制度,为淠史杭灌区水资源的优化配置提供依据。Based on the experimental result of models of rice response to water in two years and statistics data of Pi-Shi-Hang irrigation district, the optimal irrigation model of rice response to water in this area was established and its structure and parameters were determined. In order to provide a foundation of optimal allocation for water resources,the yield oriented optimal irrigation procedure was proposed by adopting DPSA in different years.
