The Construction And Implementation Of Huanghuai Plain Straw Resources Information System

As the society development, the contradiction of energy's supply and need becomes more and more intensify,traditional energy will be Exhausted,at this time, vigorously developing renewable energy particularly biomass energy will have vital significance. Huanghuai plain abundant straw resources the regional straw resources macro grasp, have have Extremely rich biomass energy, grsping Straw Resources in this region, Understanding the Total of Biomass resources,Spatial distribution characteristics of the region,Regional comparative advantage of crops etc. is the issue that we are currently facing. Through the Build of the Huanghuai Plain straw resource information System, we have more macro more intuitive understanding and awareness of the region straw resources quantity and distribution.By joint Chinese-German technical project (2007DFB70200) and Shandong provincial natural science foundation (Y2008E10),this paper in the foundation of MAPGIS applications and SQL database applications , in the support of Advantage Index model, compiles Huanghuai plain 25 cities 2006, 2007 and 2008 various crops's Statistical Yearbook data ,establishes the region's straw resource information SQL database, combining Huanghuai plain counties's, towns's and provinces's spatial information data, according to the GIS design flow, analyzes and designes the Huanghuai plain straw resources information system.,and based VC development language and MAPGIS secondary development components , the author establishes Huanghuai plain straw resources information system. Study technology route is:â‘ the analysis of Huanghuai Plain straw resource information system;â‘¡the design of system;â‘¢the building of database;â‘£the realization of System.This paper describes from five respects:The first part describes research Purpose and significance, elaborates the international geographic information system developed by Research and straw resources statistics and Utilization before the main content,and then describes the main research Content for the database construction,straw resource Spatial distribution and use patterns analysis, system design and system development, the last section discusses in this article using the technology routes, methods, development environments and tools, and the technology of database development and geographical Information Systems secondary development.The second paragraph explains Huanghuai plain's location and natural conditions,socioeconomic conditions and agricultural production status.In the third paragraph the author analyses deeply and designs the system following GIS design flowchart system , analyes data sources,system requirements in detail,and analyes the feasibility of the System function, then detailedly introduces the system's overall design and detailed design which detailed design contents 2 chapters which are system function design and system database design.The fourth paragraph describes the Huang-Huai plain straw resources information system's basic functions, such as user management, data source management and browsing of data, data query functions such as county data query functions of the City data query functions and provincial data query function, data analysis functions such as map operation, comparative analysis and crop dominance index analysis function, the data update feature, backup and restore functions, and forecast functional analysis functional modules.The five paragraph summarizes the work's experience and inadequacies,concludes and prospectes on systematic follow research.
