Abstract


The application of modern information technology to transform traditional agriculture is the development trend of the contemporary world of agriculture. Widely used in agricultural information technology, the development of agricultural production in the 21st century will bring a new revolution. By constructing the potential for crop production system, spatial analysis and evaluation of the potential for crop production of various types of natural resource elements (light, temperature, water, soil) and elements of social resources, mining and provide technical support for building the core area of ??food production for the crop potential, to improve Henan food security and even national food production safety has important practical significance. And poor scalability for a range of complex and decentralized management of farmland environmental information and crop production potential model system, this paper, the calculation and analysis of farmland environmental information management and crop production potential, crop production potential evaluation process is based in Henan Province, two one of the largest economy in the crop wheat production, for example, follow the incremental model of software engineering, software component technology loosely coupled crop production potential model subsystem GIS platform, the use of VS NET 2005 SuperMap GIS 2008 and Microsoft SQL Server 2005 Technology the potential for crop production system built on the Windows platform, systematic and automated evaluation of crop production potential from the county to the Provincial crop production management for the county, and the potential of mining and the Crop Advantage zoning to provide technical support and decision support. This paper studies the content and innovations include: (1) combined farmland environmental information management, the use of C / S and B / S mode, the design of the system architecture, the potential for crop production systems provincial and county levels of organic management, reported in the county terminal submit the farmland information and social production information, and improve the timeliness and completeness of the data required for calculation and evaluation of crop production potential to solve the problem of the potential for crop production information format is not unified and decentralized management. (2) adopt new ways of increasing software engineering model, the use of OMT object-oriented modeling techniques effective mining system user roles, build a system object model, dynamic model and the functional model, improve system security, and improve the system needs and improved system structure. (3) on the basis of the soil production potential model, the introduction of socio-economic factors, the complete set for Henan potential for crop production model, the reasonableness and accuracy of the calculation results. (4) The use of software component technology integration at all levels of crop production potential member to realize the potential for crop production model subsystem, to provide for the development of the potential for crop production systems component reuse, effectively reducing the potential of the coupling between the model and system, and enhance the system scalability and maintainability.
