The Establishment And Applied Research Of Farmland Resource Database Of Hubei Province

With the steady development of farmland productivity assessment in Hubei province, the number of counties assessed is escalating. The assessment data mainly includes spatial data and attribute data, containing natural and socio-economy attribute and farmland productivity grade. In the process of agricultural information, how to store, organize and manage the abundant spatial data of farmland resource becomes a key problem faces agricultural research workers. Besides, both how to play the role of various results in the spatial database and explore practical spread data way and how to use spatial location to connect spatial reports deserve more attention and consideration.After the deep survey and demand analysis, the paper puts forward the overall structural framing of farmland resource spatial database of Hubei province, and conducts detailed logic design, conceptual design and physical design; On the basis of data dictionary and the farmland resource spatial data, organize, standardize and normalize all farmland resource data; Import all the data into Oracle via ArcSDE; Then, do in-depth research and discuss on performance tuning and backup optimization of farmland resource spatial database of Hubei province.In order to play the full role of farmland resource spatial database of Hubei province, realize sharing and efficient promotion of farmland resource data, and do data exchange support for establishing "Agriculture Information Service System of Hubei Province", the research adopts ArcGIS Server and ArcGIS API for Silverlight to build "Farmland Resource Management System of Hubei Province", which realizes on-line and real-time query data information of farmland productivity assessment, as well as prompts the perfect combination of spatial data and report results(non-spatial data). Meanwhile, the system perfects the functions of "Agriculture Information Service System of Hubei Province" to a large extent, promotes the service value of whole service system, and makes great contribution to speed up Chinese agricultural informatization process, offer agriculture information service and accelerate the development of a new socialist countryside...
