Modern water needs information technology. Water information application issues highlighted, however, it has characteristics. To share resources, integration of applications, it is necessary to integrated water information:generous service platform, components of information processing, and the application of innovative models. Depth understanding of the needs, information associated with the knowledge mapping, organized the application process, description of the events and themes, The data, information and knowledge visualization were store experience with maps and extend the application with case-based reasoning; The business methods and models were component-based and standardized; Provide information services by subject, provide computing services by the need, provide the decision-making by personalized services; from high-performance computing and visualization performance create a parallel system and carried out the calculation experiments. With the satellite remote sensing images and real photographs of composite applications, from multi-image information and the development changes of the overall in the value to mining the value of information; Mainly to achieve "human-computer connections" in the integrated service platform to provide information, knowledge, decision-making services. By the platform, components, themes, knowledge mapping, visualization tools to form a new model:Application by the platform support; By the components, the subject and knowledge mapping organized the application rapidly; The showed by multi-information visualization. In the Personalized custom applications and related industries standard-setting, Play the role of industry-oriented, gradually extend the application of new model. This paper's main results are as follows:(1) Using knowledge mapping to achieve the expression of knowledge visualization, and knowledge mapping book products.â‘ Take the knowledge acquisition and expression based the process as a means, to establishment the knowledge mapping of water information and knowledge, Using knowledge mapping to link the information, organize the information in the application process, describe the events and the application of the theme.â‘¡Research the human-machine mechanism of supported by the knowledge mapping. From the information perception, integration point of view, use of empirical methods and lessons learned, research the application of water information using expert knowledge and process knowledge mapping, achieve knowledge sharing and transfer mechanisms, laws, and to improve the efficiency of knowledge transfer channels.â‘¢Research the mechanism of groups wisdom on knowledge mapping indorsation. Use the empirical, based on the knowledge mapping; research the individual knowledge into collective wisdom's mechanism, laws, and support groups, creative, guide groups of experts to conduct in-depth analysis and demonstration. Through the groups of experts knowledge transfer, form a "group memory", to promote the emergence of collective wisdom.(2) Adapt to the water information business applications, in accordance with the components development standards, development of presentation layer and business layer components. Expand the traditional model's reliance on the information, development of new models, and gradually component. Continuously enriched, completed the application component library. Use the component library (have a certain foundation), to resolve structural applications, knowledge resources sharing, standardize the application of the process components and services, For rapid integration and the formation of different applications to create a comprehensive integrated platform combining human-computer foundation, combined with a platform to promote the new model, and gradually build a support group of experts discuss the "knowledge market".(3) Use the middleware, grid, meta-synthetic engineering office technologies to build multi-service platform system. Using the platform to provide data, information, and knowledge integration; Platform provides three services:In accordance with the theme provide the information services, the need to provide computing services and the personalized service organizations provide the decision-making; Established an open growth knowledge system With the platform,it can make the system convenient service closest practical, long-term vitality; In the platform, store experience with knowledge mapping and extend the application with case-based reasoning; Through the Knowledge integration and evaluation, excavation good decision-making knowledge, from qualitative to quantitative, summed up and refined the law to delivery services better.(4) For the concrete application themes, use the model of platform supported, develop individualized applications. Using flood forecasting,reservoir dispatching and emergency management which are based on platform as examples, use a series of knowledge graphs to express the themes, organically combined the knowledge graphs,platform and application, test the efficiency and practicality of information,knowledge and decision service.(5) With the continuous enrichment of business application components library (componentization of the process and solution for solving the problem),theme service standards library(form application themes driven by events),application knowledge graphs library(the process or method for solving the problem,information fusion,formation of knowledge being graphical). Data center became themes service center facing service, thus propose practical data center construction scheme. Now, multi-distributed data resource was distributed stored and relatively abstract, provide data individually in the application, it is no semantic and hard to understand. Only change the data to be information by adding semantic can improve the application efficiency and value. So there is great practical significance to design the available and operable data center.(6) Discuss the formation of information integration from themes to knowledge graphs, compose a new application model by platform,component,theme,knowledge graphs and Visualization tools. The platform can support the application; using the component,themes and knowledge graphs can organize application fast; using the multivariate information visualization can display application more intuitively; take the multivariate information combination,display the decision process by knowledge,using platform to support services,convenient organize application as the recent application model, and popularize it continuous.(7) The analysis and application of MODIS remote sensing informations based on platform. Under the support of remote sensing technique, prove the utilization rate of multivariate information, Take the information combination and the application of MODIS remote sensing informations as the emphasis, excavate information value by the variation of multivariate information and Overall image, could combine the point type information,linear information and Surface information by integrating the MODIS information, realize the trinity flood forecasting.(8) Combining the grid technique with visualization technique, to create artificial parallel systems for water Information application. Under the high-performance calculation and visualization, support calculating services from the active and passive aspects, and carry on computational experiments. Analyze and demonstrate the flood dispatching.(9) Development of the water resources business application service center faced to service. Realize the integration of data and business by components, realize application integration by combining the knowledge graphs and services, realize meta-synthesis by platform, realize the water resources business application integrated service system by water resources application center.
