Design And Implementation Of Information Management System For Drought Situation In Shandong Province

On soil drought (moisture) for monitoring and prediction of drought, is a basic work. With the development of science and technology, soil drought (moisture) monitoring technology is also in constant improvement, especially the continuous updating of computer technology and GIS technology is mature and perfect, for drought monitoring (moisture) provides a new method and technology. Based on the analysis of the current situation of the development of the domestic and foreign drought monitoring, using the network communication technology, computer technology, sensor technology, GIS technology and database technology to design the Shandong province drought information management system, and has carried on the test of the system, to achieve the desired results, the main research work and results are as follows:1, combined with the actual situation in Shandong Province, further defined the system development overall mentality and the technical route, design and development of the Shandong province drought information management system, to provide technical support for the development of drought monitoring system after the other regions.2, introduces the related knowledge of WebGIS, B/S, database, MapXtreme, development of drought monitoring Web management system using these technologies, the realization of network office management decision-making departments, the application of the GIS technology in the system, realize the integration of GIS technology and system.3, each part of the Shandong province drought information management system structure, function, principle of the whole system is simply described; using SQL Server 2008 as the database, according to the three paradigm for the design of drought information management system database.4, the use of GIS technology to analyze the data acquisition system, obtains the soil moisture distribution in the whole study area; the establishment of soil moisture prediction model, which provides support for soil moisture prediction in a short time. Drought information management software system combined B/S and C/S structure model in the technology design, relying on the background of the SQLServer database and GIS geographic information application platform has been built, using the integrated monitoring site monitoring and forecasting data has built the hydrological function of the software, the full realization of real-time, fast, accurately collect all kinds of information related to the province’s soil moisture the soil moisture content, such as information, hydrological information, meteorological information etc.. Through a comprehensive analysis of all kinds of information, real-time monitoring of soil moisture content development process and development trend. So that the provincial flood control and drought relief headquarters can be fully understand the effect of moisture content and moisture situation of agricultural production and the life of the masses caused by drought, drought, take effective measures, in order to make losses and the impact to the minimum. In the wide area network coverage, users need only a browser software, can visit the website of drought information management software system. Drought information management software system is divided into four parts:data transfer software, database management software maintenance, flood control and drought relief decision support system and information service platform. The integrated application of data acquisition, database management, data and web information publication three functions respectively realize.
