| Agricultural information management system is carried out through the acquisition ofagricultural production, agricultural data organization, storage, sorting and analysis, so as toguide the practice of agricultural production, information management system and aidedmanagement decision. It is the basic project of agricultural informatization and modernization.At present, foreign countries have a number of commercialization of agricultural informationcollection management software products, can real-time acquisition the crops in the fields ofagricultural information, efficient storage of the data acquisition, and processing thecorresponding calculation, provide scientific basis for crop management. But in China,agricultural information acquisition in manual acquisition, acquisition of low efficiency, higherror rate, agricultural information management by using EXCEL, data storage, processingand releasing the lack of uniform standards, management software development ofagricultural information collection has a certain degree of development, but has not reachedthe production stage.In this paper, by consulting the Beijing agricultural technology extension station expertopinion, the wheat crop information is divided into13periods, construction of agriculturalinformation model of each growth period of wheat, defines the types of internal data of eachperiod, the wheat crop data standardization. On the basis of this model, using Microsoft SQLServer2005, designs and creates the wheat crop database. According to the user requirementanalysis, designs the main functions of the system. Using computer technology, databasetechnology, network technology, geographic information system technology, develops adistributed wheat crop management information system based on model and GIS. The systemprovides the following functions: file management function, realizes the data compatibleimport of wheat of agricultural information, history and the existing data were derived; thefunction of data management, the use of database technology and network technology, thewheat crop information collection, storage, query, sharing and maintenance; map managementfunction, using the component GIS technology, realizes the monitoring point of each districtand county of Beijing city spatial display and query as well as the basic map operation;statistical analysis functions, in the specific business need analysis basis, build cross statisticsat different growth stages, and in different years, different regions, different index analysis model, using the chart control, realizes the automation statistical analysis of wheat cropinformation and generate the chart, while supporting the results in the form of output statisticsfile and chart; user management function, the system role authentication login, user rating,realizes the data access control, ensure the security of data. Finally, system in the city ofBeijing agricultural technology extension station data based on testing, results show that thedesign idea and structure framework of system, the wheat crop management informationneeds, can better compatible with uneven history data format, data entry is simple andconvenient, management efficiency, visual analysis results, the digital implementation ofmanagement and analysis of Beijing city the wheat crop information. |
