Forest Management Optimization And Subsidiary Decision-making System Based On GIS Technology

With the development of spatial information technology, geographic information system (GIS) has been applied extensively in almost every field. Supporting with GIS technology, all types of monoscopic programming & planning and decision-making in forestry have been making great progress and being more and more prefect. In order to regulate and optimize the forest distribution, and make the forest management plan scientifically, practicably and maneuverability, it is necessary for forest management units to build up forest management scheme integrated with information technology. This paper build up a forest management optimization and subsidiary decision-making system (FOSDS) ,which takes Citystar and Visual Foxpro as the workstation, Powerbuilder as programming language, and use OLE/ODBC technology to process system integration and model analysis method. This FOSDS consists of three subsystems including database management, optimization & subsidiary decision-making and map-making subsystems. According to the pattern of application of GIS,this FOSDS takes the Wuguang forest farm as an example to develop the forest management and working plan. The application of this FOSDS focus on as follow: (I) Taking database of the FOSDS as data source of models, exporting the analysis result of models through the FOSDOS to achieve the forest management optimization and subsidiary decision. (2)By using analytic hierarchy process, linear programming, multiobjective decision, principal component analysis and the analysis models integrated with GIS to process the spatial model analysis of the FOSDS. (3) Having finished the data of statistics, site type classification, management type organization, forest felling-plan, silvicultural planning, optimization of project, forest conversation pragramming and special topic map.
