Research on technology of forest subcompartments management plan assistant decision

Abstract

A forest management plan, the core of forest management, has as its main object the country or forest farm. Implementation of what to factor into annual requirements with a focus on subcompartments is important for research on decision-making support systems of the forest management plan; however, data based on subcompartments is rarely reported. Thus, this study determined a method and technical route for plantation management by compiling subcompartment data to produce management plans. An intelligent selection method of subcompartments needed to establish a management plan was researched, and then a suitability evaluation method of subcompartments and a management plan reasoning method of subcompartments were selected. Next, a Forest Subcompartment Management Plan Assistant Decision-Making System was designed and implemented. The forest management plan was analyzed by forest management experts, and a knowledge base and inference engine of a decision support system were built. This system used production rules according to the state of the stand, site conditions, management objectives, and other conditions to determine management choices. From this an intelligent design and manually aided design were developed using Visual Studio 2008 and ArcGIS Engine 9.3 as developing tools, and Access as the database engine to complete construction of the system. The system could help users intelligently selected management subcompartments based on management assignment, then compiled subcompartments management plan by two ways, which were provided by the system. It could be used in forest farms, solved forest management with effective choices and management plan compilation assistance problems and effectively improved the digital level of forest management.
