无人机为获取高时空分辨率的遥感数据提供了经济灵活的工具,为植物生态学家开展从个体到区域尺度的生态学研究提供了新的机遇和手段.但作为一种新兴的技术手段,当前无人机遥感在植物生态学中的应用仍充满了挑战,植物生态学的科研需求与无人机遥感的生态应用需要更为深入的融合.本文综述了无人机遥感技术在植物生态学中的应用,展望了无人机在植物生态学研究中的应用前景.在所综述的400篇文献中,59％的文章发表于非植物生态学领域的遥感类期刊,遥感学者与生态学者的关注点存在较大差异.当前的研究集中在无人机遥感的技术层面,如数据处理和遥感反演方法等,对生态学问题本身的关注较少.综述的文献中,61％的研究案例集中在群落尺度,可见光(RGB)相机和多光谱相机是最常用的传感器类型(75％).无人机遥感数据中蕴藏着诸多待挖掘的、有重要意义的生态参数,这些参数有助于我们识别林窗的几何特征,构建林冠的化学组合,更好地了解林冠表面的不规则性和群落的异质性.无人机遥感技术在植物生态学研究中的深入应用,需要集植物生态学家和遥感专家之合力共同推进.“,”Aims Unmanned aerial vehicles (UAVs),i.e.drones,have recently emerged as cost-effective and flexible tools for acquiring remote sensing data with fine spatial and temporal resolution.It provides a new method and opportunity for plant ecologists to study issues from individual to regional scales.However,as a new method,UAVs remote sensing applications in plant ecology are still challenged.The needs of plant ecology research and the application development of UAVs remote sensing should be better integrated.Methods This report provides a comprehensive review of UAV-based remote sensing applications in plant ecology to synthesize prospects of applying drones to advance plant ecology research.Important Findings Of the 400 references,59％ were published in remote sensing journals rather than in plant ecology journals,reflecting a substantial gap between the interests of remote sensing experts and plant ecologists.Most of the studies focused on UAV remote sensing\'s technical aspects,such as data processing and remote sensing inversion,with little attention on answering ecological questions.There were 61％ of studies involved community-scale research.RGB and multispectral cameras were the most used sensors (75％).More ecologically meaningful parameters can be extracted from UAV data to better understand the canopy surface irregularity and community heterogeneity,identify geometrical characteristics of canopy gaps and construct canopy chemical assemblies from living vegetation volumes.More cooperation between plant ecologists and remote sensing experts is needed to promote UAV remote sensing in advancing plant ecology research.
