Abstract:

In order to improve the management efficiency of forest resources management units,scientifically guide the preparation of forest management plans,and realize the whole process of forest management informatization,this paper conducted research and discussion on the construction and related technologies of the dynamic monitoring and evaluation system of forest resources. Through integrating various forest resources survey databases over the years and various scattered thematic archive data,this paper intuitively analyzed the spatial distribution characteristics and dynamic changes of forest resources in the management unit area. At the same time,by combining closely the forest multi-functional management evaluation and forest resource monitoring,introducing model analysis method and establishing index system of different source items,it evaluated and analyzed the multi-functional management such as silviculture,forest harvesting,non-wood resource utilization and forest recreation,forest health and protection,etc,so as to automatically extract priority development areas,and output visual evaluation results to provide data support for forest multi-functional management and regulation measures. The practical results demonstrated that the system had strong reliability and practicability,which could satisfy the multi-dimensional needs of forest resource management,and would provide decision-making basis and scientific practical guidance for sustainable forest management.

Key words: forest management unit, forest resources, dynamic monitoring and evaluation, forest management
