森林经营决策模拟系统的设计与实现

以湖南省株洲市攸县黄丰桥林场为研究对象,以Visual Basic和Access数据库为开发平台,通过模拟生成一个与现实林分相似的虚拟林分,应用Weibull分布、Monte Carlo方法和随机分布方法对林分直径结构进行模拟;利用数学分析和统计方法计算林分经营决策因子;根据林分经营决策因子的决策准则,建立森林经营决策模型,然后对其进行检验.由此设计并实现了森林经营决策模拟系统.该系统可以动态地模拟林分直径结构,模拟结果非常稳定;能动态地模拟林木的地面位置;实现了模拟数据结果的实时浏览查看、图表图像显示等多项功能.

Design and Realization of the Simulation System for Forest Management Decision

Forest management can improve and adjust the tree distribution of a stand.This paper simulates a real stand by computer,manages the stand's diameter distribution and random distribution by Weibull,Monte Carlo based on forest growth.Then,it calculates the decision factors by mathematical analysis and statistics.Taking Huangfengqiao Forest Farm as the research object and,visual basic and access database as the developing platform,a simulation model of forest management has been established and tested.The system can dynamically simulate trees' diameter,with steady results,and their ground position,realizing such functions as browsing,searching and displaying of charts and images.
