Research On Simulation System Of Water Dispatch In The Yellow River Irrigated Area Of Ningxia

The water resources are considered as not only strategic foundation resources that supporting the coordinated and healthily sustained development of social and economy, but a factor that controlling the benign cycle between the ecosystem and the environment. The shortage of water resources is one of most serious challenges to human's living, producing and development. The Ningxia average per person water resources is serious insufficient, belongs extremely lacks the water area.The water resources shortage has brought the serious hindrance to Ningxia's economical development, simultaneously also gave the society stably disadvantageous factor. From forward looked that, the water resources short problem of the Ningxia and even the Yellow River could be solved by the cross basin water transfer. But, looked from the near future that, the problem only solved by the water resources optimization dispatch and enhances the water resources using efficiency. Therefore this paper according to the water dispatch present situation of the Yellow river irrigated area of Ningxia, researched the water dispatch problem using the simulation system theory, proposed for the first time carries on the water dispatch using the CBR method.At the same time, for the water dispatch model effectively to apply to the production practice, further enhances the local water resource management information level, the CBR technology, the Web technology, the Frame technology, the Ajax technology, RBAC as well as the MVC software design pattern and the module develops and so on the advanced software design development theory and the technology has applied to water dispatch simulation system research and development in the Yellow river irrigated area of Ningxia, Further impelled the water dispatch application software development, has the certain application innovation. The water dispatch data information synthesis management and the water dispatch operation real-time utilization has been realized, a scientific policy-making platform for the water dispatch management has been built. Through the example application, this system in technical realization feasibility and the rationality has been proved. This system has a better extension and the probability, may in this preliminary study achievement, further expand practical application operation, made it to perfect into a water dispatch the synthesis application service and the policy-making platform. Paper main contents and achievement outlines as follows:(1) The Water dispatch method and its good and bad points at present of the Yellow river irrigated area of Ningxia has been analyzed. The water dispatch method such as the traditional runoff adjustment method and based on the simulation system theory has been classified and summarized, and good and bad points of various water dispatch methods has been analyzed, finally determined using CBR for the water dispatch.(2) The course water routing model has been established. River course water routing model based on the simulation system theory has been established, course water routing research mentality and the research technique are expounded, definite method of the parameter of channel water routing model is produced, and the policy-making basis for the next step of water dispatch is provided.(3) Using CBR for water dispatch, the CBR basic principle, the characteristic and the flow of work are analyzed, and applied it to the water dispatch. The CBR essential technology, such as water dispatch case express, the retrieve, the revise, the retain and so on are solved, and taken Ningxia TangLai channel as an example, carried on the example analysis, the process of using CBR real-time water dispatch is explained.(4) Designing and implement of Water dispatch simulation system. Based on the modern information technology, water dispatch simulation system of the Yellow river irrigated area of Ningxia is constructed, and a highly effective and operational comprehensive information platform for the Ningxia water dispatch decision-making, the consultation and the implementation is provided.
