摘 要:以东北用材林为研究对象,在构建林木三维图形可视化基础上,研制用材林精细化经营系统软件。该系统主要应用OpenGL开放式图形库技术和数据库技术,采用Visual Basic语言建立;该系统基于林木的实测数据和主要树种的生长规律,结合林木的生长模型和形态结构,构建林木的三维可视化模型;该系统在树木和枝条的ER模型基础上,建立了树木和枝条的一对多access数据库,将林木的胸径、树高、枝条等信息存储起来,并采用ADO技术对数据库进行读写,便于程序操作;该系统在林木可视化基础上,可以施用不同强度的抚育间伐、不同比例的修枝等措施,分析对林木生长的影响,可以得到最优的经营方案;该系统应用了OpenGL中的选择和反馈机制,支持交互式操作。通过研究,该系统可以用于林业的生产作业中,可以解决实际的经营问题。Taking the Northeast timber forest as studying object,delicacy management software is developed on the basis of the visualization of3D forest timbers.OpenGL,database technology and Visual Basic were used to establish the system.Based on the measured data of trees and the growth rules of main tree species,combined with the growth model and morphological structure of trees,the three-dimensional visualization model of timbers was constructed.According to the ER model of trees and branches,a one-to-many access database was established,which could store the DBH,tree height,branches and other information.ADO technology was used to read and write the database,which was easy to operate the program.On the basis of visualization,we can use different intensity tending thinning,different proportion of pruning and other measures to analyze the impact on the growth of trees,and to get the best plan.Selection and feedback mechanism in OpenGL were used to support interactive operation.This system could be used in forestry production operations and could solve the actual operational problems.
