200多年来，地块尺度测量一直是森林调查和报告的基础。通过最近与航空和卫星遥感相结合，人工测量地块规模的植被结构现已成为对我国森林资源进行地貌、大陆和国际测绘的基础。地面激光扫描（TLS）在十多年前首次被证明用于地块尺度测量，并暗示这些仪器可以取代手动测量方法。尽管TLS可以捕获无与伦比的结构信息，但情况并非如此。为了使TLS充分发挥其潜力，这些工具不能被视为现有基于图的测量的逻辑进展。TLS必须被视为一种颠覆性技术，需要重新思考植被调查及其在广泛学科中的应用。我们回顾了TLS作为一种绘图尺度测量工具的发展，包括仪器硬件和关键数据处理方法的演变。我们强调了两个广泛的数据建模方法的差距概率和几何建模和基础理论，这些。最后，我们讨论了未来的前景，增加利用TLS的地块规模的森林评估和森林监测。
Plot-scale measurements have been the foundation for forest surveys and reporting for over 200 years. Through recent integration with airborne and satellite remote sensing, manual measurements of vegetation structure at the plot scale are now the basis for landscape, continental and international mapping of our forest resources. The use of terrestrial laser scanning (TLS) for plot-scale measurement was first demonstrated over a decade ago, with the intimation that these instruments could replace manual measurement methods. This has not yet been the case, despite the unparalleled structural information that TLS can capture. For TLS to reach its full potential, these instruments cannot be viewed as a logical progression of existing plot-based measurement. TLS must be viewed as a disruptive technology that requires a rethink of vegetation surveys and their application across a wide range of disciplines. We review the development of TLS as a plot-scale measurement tool, including the evolution of both instrument hardware and key data processing methodologies. We highlight two broad data modelling approaches of gap probability and geometrical modelling and the basic theory that underpins these. Finally, we discuss the future prospects for increasing the utilisation of TLS for plot-scale forest assessment and forest monitoring.
