The Information System Of The Price,Supply And Demand Agricultural Products Base On WebGIS

As a major agricultural country in the world,China’s three issuesconcerning agriculture,countryside and farmers are closely related to the quality ofChinese people,the economic development,the stability of Chinese society as well asthe strength and prosperousness of China.The information of the price,supply anddemand of agricultural products,which is one of the objects of the three issuesconcerning agriculture,countryside and farmers,has obvious relationship withspace,time and the economy of natural society.The available information system atpresent can share the information of the price,supply and demand of agriculturalproducts,of which the spatial characteristic can not be showed directly,however.Thesystem also can not add up the information and it’s variation tendency of regionalagricultural products.With the rapid development and further application of the technology of computer,database and internet,"Networking" has been the new characteristic and tendency ofthe development of GIS.In order to achieve the sharing and interoperability of spatialdata, WebGIS, which has been widely applied to various fields, publishes and appliesthe geographical spatial data through network.This essay, which first introduces the characteristic, model, the realization wayand building platform of WebGIS, then combines the technology of WebGIS, doessome research on building the structure of WebGIS systematically.This essay,which combines spatial database technology, RIA, GeoServer openingsource platform designation and the developing of geographical information system ofthe price,supply and demand of agricultural products,has acquired data frommulti-source,showed the information tends of agriculture products,processed and analyzed the spatial data.It also has provided support to management and makingstrategic decisions for relevant departments,all-wave geographical information serviceof the price,supply and demand of agricultural products for whole society,as a resultraises the level,efficiency and quality of the service of the three issues concerningagriculture,countryside and farmers as a whole.
