地基激光雷达技术在森林调查中的应用研究进展

Research Progress in TLS Technology in Forest Investigation

森林资源的实时监测是森林经营管理的重要基础。地基激光雷达以其快速性、准确性、非破坏性和自动化等优点逐渐取代了传统的森林资源调查方法,可用于单木参数和林分信息的提取,特别是传统方法难以获取的冠层信息,并解决森林地上生物量估计中的不确定性。文中主要介绍地基激光雷达技术在森林资源调查中应用的研究现状,分析讨论该技术的优缺点,并对其未来的应用前景进行展望。

Real-time monitoring of forest resources is an important foundation for forest management.Terrestrial Laser Scanning gradually replaces the traditional forest resource investigation method owing to its fastness,accuracy,non-destructiveness and automation. It can be used for the extraction of single tree parameters and forest stand information,especially the canopy information that is difficult to obtain with traditional methods,and solves the uncertainty in the estimation of aboveground biomass in forest. This paper mainly introduced the research status of Terrestrial Laser Scanning technology in forest resource investigation,analyzed and discussed the advantages and disadvantages of the technology,and prospected its future application.
