Research And Implement Of Decision Support System On Silviculture And Management Of Poplar Fast-Growing Plantation

Forestry informatization is the only way for the development of forestry.To develop fast-growing plantation,we should achieve informatization in management,intelligent in making decision,and raising information applying level in silviculture and management of fast-growing plantation.Based on the existing research results,this paper analyses the theory and methods of site quality evaluation,selects appropriate method for poplar and applies it to the decision support system by using AHP method.The paper studies expert knowledge of plantation silviculture,designs the reasoning engine and knowledge base and implements the silviculture design subsystem.Integrating with the theory and methods of economic analysis,the paper analyses economic indicators of silviculture design by using dynamic economic analysis methods and carries out uncertainty analysis, draw analysis chart and so on.The system evaluates site quality.Base on the result and site information,it recommends silviculture designs.According to the changes of parameters and users' requirement,the system analyses the designs by using dynamic economic analysis methods and uncertainty analysis methods.By doing this,the system assists users to select proper designs.In the end,through the application of the system,it proves that the system can be used easily.It provides exact and valid auxiliary information.The results of economic analysis are scientific and sound.
