Rapid development and applications of unmanned aerial vehicles (UAVs) provide promising solutions to and new opportunities for environmental monitoring. Owing to their flexibility in flight scheduling, high spatial resolution, and costs-effectiveness, UAVs have become a popular tool for monitoring dynamic environmental processes, such as emergence and outbreak of harmful algae blooms (HABs). The HABs outbreak, often linked with anthropogenic eutrophication, has become a serious environmental health problem that threats our communities. Existing studies show that UAV-based HABs monitoring is a cost-effective means of assisting environmental managers in developing precautionary warning system and coping strategies. This article summarized the state-of-the-art of using UAVs and lightweight onboard multispectral sensors for HABs monitoring from the perspective of quantitative remote sensing. It culminates in a discussion of challenges and opportunities for future research and applications on drone-based HABs monitoring.
无人机（UAV）的快速发展和应用为环境监测提供了有前景的解决方案和新机遇。由于其在飞行计划安排方面的灵活性、高空间分辨率和成本效益，无人机已成为监测动态环境过程（如有害藻华（HAB）的出现和爆发）的流行工具。HAB 的爆发通常与人为富营养化有关，已成为威胁我们社区的严重环境健康问题。现有研究表明，基于无人机的 HAB 监测是一种具有成本效益的手段，可以帮助环境管理者开发预警系统和应对策略。本文从定量遥感的角度总结了使用无人机和轻型机载多光谱传感器监测 HAB 的最新技术。最后讨论了基于无人机的 HAB 监测未来研究和应用的挑战和机遇。
