The Farmland Information Management Assistant Decision System Based On WebGIS Technology

With the continuous development of large-scale farming,modern agriculture is moving from thetraditional manual rugged style management toward refinement,information technology,modern agriculturalscientific direction of gradual transition to agriculture information to promote agricultural modernization,forthe promotion of sustained and coordinated economic and social development of great significance.In recentyears,Farm in Heilongjiang province due to the increasing amount of agricultural information,larger defects inthe intuitive and data completeness in the past with books records or simply use the database record fieldinformation.Data in the database is manifested only in the form of text,form of rigid, but complex farmlandgeographical situation is hidden behind the text,Their specific circumstances and can not be intuitivejudgment.How intuitive and effective information management of farmland become the main issues need to beaddressed in the current farm.For the needs of the current farm in Heilongjiang Province,through the comparative analysis of theexisting GIS software, select the ESRI’s ArcServer9.3as map server publishing platform,the combined NETsoftware development environment,designed “based on Web GIS technology field information managementdecision support system”. The architecture of the system is based on B/S,with ArcServer9.3dynamicallygenerated field information of thematic maps,Intuitive and concrete show farm farmland geographicinformation,Farmland GIS data online link,inquiry,analysis,dynamic update of the database,online dynamicmanagement and decision support functions.The establishment of the system to improve farm management level within the jurisdiction of theagricultural resources and geographic information,intuitive query ways to enhance the work efficiency,in theshortest time for the user to provide a scientific basis for decision making,the fastest way to understand thespecific circumstances of the farmland,facilitate the development of the next agricultural productionplan,saving a variety of agricultural material resources,reduce agricultural waste of resources pollution of theenvironment,promote the development of ecological agriculture,effectively change to the former artificialdecision-making not comprehensive and inaccuracy.
