| The forest management could improve and adjust trees distribution of a stand This paper simulated a real stand by computer, managed the stand diameter distribution by Weibull, Monte Carlo and random distribution based on forest growth, then calculated the decision factors by mathematics analysis and statistics. The simulation model of forest management (FMDSS) was established lastly.The software of FMDSS includes the modules of stand diameter structure, tree position simulation, decision factors and forest management decision-making.Based on advanced technique—Microsoft Visual Basic 6.0, this multi-function simulation system has friendly user interface, availability of software upgrade and maintenance, intellectual property. At the same time, it also was integrated database (Access) and grid management, graphics and image, multimedia techniques, and etc.FMDSS runs very well, and also is convenient to operate and maintenance. It reserves an interface for further development. Can simulate tree's diameter dynamically. The result showed that it runs stablefrom 1 to 100 times, it is not different that comparing with the diamemter distribution of experiment datum in HUANG Fong-qiao forestry; trees'positions is different and full trees is different, too.FMDSS system is an important tool for scientific research, teaching and management decision support, The study syncretism scientific research methods such as the forest management decision and simulation model, statistics, the chart and grid handling and computer programming. The system has stronger function, so greatly improve the feasibility of module and system in scientific research and production, and it can provide a new techniques platform for the study of forest decision management in the future. |
