摘　　要：近年来,随着林业资源管理和生态监测需求的持续增长,树木材积作为评估森林健康、实现森林可持续经营及估算森林碳储量的关键指标,其精确估算变得愈发重要。然而,传统测量树木材积的方法不仅实施难度大、效率低下,还会对森林造成一定损害。地基激光雷达技术作为一种先进的3D测量工具,在林业调查中展现出非破坏性、高效性、自动化等多重优势,已成为估算树木材积的有效手段。文中通过查阅国内外相关研究,探讨利用地基激光雷达技术估算树木材积各方法的优势及其存在的局限性,并对未来地基激光雷达技术在树木材积估算领域的研究应用进行了展望,旨在为进一步提升树木材积估算精确度及拓展其应用范围提供参考。In recent years,as the demand for forest resource management and ecological monitoring continues to grow,the accurate estimation of tree volume has become more and more important as a key indicator for forest health,sustainable forest management and forest carbon stock estimation.However,traditional methods of volume measurement are not only difficult to implement and inefficient,but also cause some damage to forests.Ground-based LiDAR technology,as an advanced 3D measurement tool,has become an effective means of estimating tree volume in forest surveys because of its multiple advantages of non-destructiveness,high efficiency and automation.In this paper,the advantages and limitations of applying ground-based LiDAR technology in tree volume estimation are discussed after the review of relevant studies at home and abroad,and the future research direction in the field is envisioned,aiming at providing references for further improving the accuracy of tree volume estimation and expanding the application scope.
