基于GMS的灌区优化配水调度及辅助决策支持模块建设

Construction of Auxiliary Decision Support Module&Optimized Water Distribution Scheduling for Irrigation Area Based on GMS

灌区优化配水调度及辅助决策支持系统作为智慧灌区平台(以下简称GMS)的功能模块,由模型库、需水量计算子模块、优化配水调度子模块、辅助决策子模块四部分组成。模型库实现了后台计算模型的开发,为各功能模块调用提供依据;需水量计算子模块实现了由作物需水量到地块需水量到渠道应灌溉水量的计算;优化配水调度子模块实现了单闸及多闸联合配水调度方案的生成;辅助决策子模块通过灌溉调度模拟优化配水调度方案,提供灌溉建议。灌区优化配水调度及辅助决策支持系统的开发为灌区管理者决策提供依据,效果显著。

The optimized water distribution scheduling and auxiliary decision support system for irrigation area as a function module of intelligent irrigation area platform(for shorter GMS as follows),is composed of four parts:model base,water demand calculation sub-module,optimized water distribution scheduling sub-module and auxiliary decision sub-module.Background calculation model is developed by means of the model base,which provides the basis for the transfer of each function module.The water demand calculation sub-module can be used to calculate water demand not only for crops,but also for fields and channels.The single and multi-gate joint water distribution scheduling schemes are generated by optimized water distribution scheduling sub-module.The auxiliary decision sub-module can be used to simulate the scheme of optimized water distribution scheduling and provide irrigation suggestions.The development of optimized water distribution scheduling and auxiliary decision support system provides basis for decision managers of irrigation area,and its effect is remarkable.
