The Analysis And Design Of Large-scale Irrigated Area Information System

With the development of computer and Internet technology by leaps and bounds, it's important to build irrigation Area information system,which has perfect function, runs reliably,uses economically.Taking the Large-scale Irrigated Area Information System as the research object, this thesis systematically analyses its domestic and foreign applications and the research present situation,and points out some defect of them,and puts forward the overall frame idea to it.Base on the computer network,set the Irrigated Area Information System gathering information acquisition and control,management analysis evaluation and decision.Carries on the investigation and the analysis with the technology of empirical Research to the domestic large-scale irrigation area organizational structure and the service flow as well as the information flow,this thesis proposes a holistic and universal model of Information System.Through detailed system design,the theoretical design and the implementation design to system each function have been carried on.We have successfully applied this model in an irrigation area of shaanxi province.The result indicated that,this model standardizes irrigation area information gathering,the transmission,and the irrigation decision-making activity.This model, for the realization of irrigation area information sharing,the improving of the irrigation area management efficiency,the realization of irrigation area water resources optimized dispatch,has provided the theory and the technical strut.
