【摘要】：无人机低空遥感系统弥补了航天和航空遥感在影像分辨率、重访周期、云层影响以及高成本等方面的不足,为中观尺度的生态学研究提供了新方法.本文介绍了轻小型无人机低空遥感系统的组成,从物种、种群、群落和生态系统尺度综述了其在生态学中的应用现状,并指出目前存在的不足和未来的发展方向,以期为无人机生态学的后续研究提供参考.无人机生态学当前面临的挑战和未来发展的方向主要有物种形态和光谱特征库的建立、物种自动识别、光谱数据与植物生理生态过程之间关系的进一步挖掘、生态系统三维立体监测、多来源多尺度遥感数据融合等.随着无人机平台技术、传感器技术以及数据传输处理技术的成熟,以无人机低空遥感技术为基础的无人机生态学将迎来发展的机遇和曙光.
[Abstract]:Unmanned aerial vehicle (UAV) low altitude remote sensing system makes up for the shortcomings of space and aviation remote sensing in image resolution, revisiting period, cloud effect and high cost, which provides a new method for ecological research on mesoscale scale. In this paper, the composition of low altitude remote sensing system for light and small UAV is introduced. Its application in ecology is summarized from the scale of species, population, community and ecosystem, and the shortcomings and future development are pointed out. In order to provide a reference for the future study of UAV ecology. The current challenges and future development directions of UAV ecology include the establishment of species morphology and spectral signature database, the automatic identification of species, and the further exploration of the relationship between spectral data and plant physiological and ecological processes. Ecosystem three-dimensional monitoring, multi-source multi-scale remote sensing data fusion and so on. With the maturity of UAV platform technology, sensor technology and data transmission processing technology, UAV ecology based on UAV low-altitude remote sensing technology will face the opportunity and dawn of development.
