Asset management of forest resources is to deepen forestry reform, an important means to achieve sustainable forest management, forest resources asset assessment is the prerequisite and basis of the asset management of forest resources. Timber forest timber assets assessment plays an important role in the assessment of forest resources assets timber forest assets assessment decision support system is the direction of the development of the field of asset evaluation of forest resources. Longshan Forest Farm in Hunan Province as a case for the practical problems that exist in the current timber forest assets assessment, such as the model operability, the information utilization levels, the low efficiency of decision-making, management information systems, modeling techniques, expert systems and decision support systems comprehensive use of the actual timber forest assets assessment, form a set of information management, model calculations, the expert decision-making in one of the intelligent decision support system. Computer operating platform, set small class data processing module, asset evaluation decision support module, Knowledge Base mount module and network connectivity modules. Which, in small classes, data processing module loaded on small class data collection, and the overall evaluation and prediction of the results of the assessment output, constitute assessment module. Asset evaluation decision support module assessment options. Derived forest regeneration data and read set reasoning rules. Knowledge Base mount module connection to the work of the decision support system and knowledge base. Network connection module timber price list, and economic indicators data online update. Through the system for the accurate calculation and improve the efficiency of timber forest assets assessment provides the possibility of using modeling technology, so that the timber stands of forest assets assessed at or near the level of experts. The system developed in compliance with the thinking of the systems engineering and software engineering methods, timber forest timber assets assessment decision support system the user needs, feasibility, functional requirements, and system functions detailed analysis to determine the strategy of system development and system operation environment; based on system analysis, system functions, system architecture, system database, the system, the World Wide Web connection process design and realization; through the realization of human-computer interaction systems, database systems, knowledge base system, method library system, model library management system, so the system has strong data management, data updates, trend forecasting, model application, the planning, the basic functions of the system output. The application shows that the system can not only achieve the high accuracy of the basic data of the forest in small classes, high-efficiency management; timber forest assets assessment decision support, and numerical simulation; will be a lot of knowledge systematization of timber forest assets assessment, competent forestry the validity of the department of forest resource management decisions, scientific.
