Study And Development On Silviculture Assistant Decision And Data Update System

The Forest Resources Information Manage System (FRIMS), was a professional application system, which combines forestry knowledge, geographical information technology, network technology, database technology, and with the usage of computer as tool. The Forest Cultivates Consulting System (FCCS) and Data Update System (DUS) were the subsystem of FRIMS. FCCS provided the decision-makers scientific reference and assisted them to choose better plans, DUS realized updating in time and estimate the trends of primary class in advance.This thesis has introduced the research approach of the FRIMS upon the whole, emphatically discussed the background, technologies and method of FCCS and DUS, and then put forward a plan of design and solution. It discussed the geographical information technology in the auxiliary application while analyzing of system, and utilized the network technology to optimize the plan.FCCS analyzed several crucial problems such as selecting spot, analyzing information, giving the optional plans and output. Probe into and put forward to the whole solution of FCCS. It was discussed that the key technologies GIS component and system structure. DUS presented the building of management activities database and growing model database.At the same time this thesis introduces VC ++. development with ADO and MAPOBJECTS components in details, and it is a good reference for developer.
