【摘要】 针对目标树经营实践中林分作业设计这一难题,在地理信息系统(GIS)技术支持和C#开发环境下,对林分进行了重建和可视化,探讨了林分作业设计中基于GIS的关键技术,根据林木个体差异和林木竞争模型,研究和开发了目标树经营可视化辅助决策系统,实现了目标树和干扰树的自动判定和林分作业前后场景模拟及林分作业评价。结果证明,该系统具有功能强大、操作简单、可维护性好的特点。该系统的研发使得目标树经营作业推广成为可能。更多还原

【Abstract】 To assist with stand operation design in target tree management,the Target Tree Management Assistant Decision-Making System was developed using GIS technology and C sharp(C#) language based on a model for individual forest tree size differences and competition.The system involved construction and visualization of a stand,effective spatial structure analysis,automatic judgment of forest tree types,scene simulation of pre-and post-stand operations,and stand operation assessment.Key technologies based on GIS involvement in the system were also discussed.Results showed that the system was rigorous with easy manipulation and high maintainability.This system could allow widespread popularization and application of target tree management.更多还原
