Study On Forest Resource Subcompartment Data Update System

In order to manage forest resources dynamically, master the history, status and variation, assess the effects of forest management, prepare the forest management plan and arrange the business activities, updating the forest resources subcompartment data is an important task. Xiuwen county, Guizhou Province as the study area, analyze of domestic study on forest resources subcompartmente data update in the forest resources information management, compare the information management technologies, select the. NET+ArcGIS Engine 9.2+Geodatabase systems development technologe. Study on the forest resources subcompartment change factor and change reason, design the storage methods of forest resources subcompartment change data,and the methods and processes of subcompartment spatial and attribute data updating.Based on the above, design the function and the logical structure of data updating subsystem in the forest resources information management system, and design and develop the system functional modules, including the maintenance of updating database, attribute data updating and growth model updating, design the module functions and logic flow diagram. design a system database and complete the prototype system. This system provide forest resources spatial and attribute data management, straightforward information browsing and retrieval services for forestry sector. Meanwhile, manage the forest resources attribute data and spatial data simultaneously, ensure real-time operating data, support decision-making for the forestry sector.
