The sustainable use of medicinal plants is the foundation of the inheritance of traditional Chinese medicine(TCM) and the acquisition of information on medicinal plants is the basis for the development of TCM. The traditional methods of investigating medicinal plant resources are disadvantageous in strong subjectivity and poor timeliness, making it difficult to real-time monitor medicinal plant resources. In recent years, remote sensing technology has become an important means of obtaining information on medicinal plants. The application of this technology has made up for the shortcomings of traditional methods. The open-access remote sensing data with medium spatial resolution satellites provide an opportunity for extracting information on medicinal plant resources. This study firstly introduced the principles of remote sensing technology, summarized the satellites and the parameters commonly used in the field of medicinal plant resources, and compared the survey methods of remote sensing technology with traditional methods. Secondly, it reviewed the applications of remote sensing technology in the extraction of information on the cultivation of medicinal plants and the common methods for extracting the planting structure information of medicinal plants based on remote sensing technology. Thirdly, the applications of remote sensing technology in the investigation and monitoring of medicinal plants were further analyzed with the research objects divided into wild and cultivated medicinal plants according to the characteristics of the habitats. Finally, it pointed out the key unsolved technical problems in the remote sensing monitoring of medicinal plant resources, and proposed solutions for the intelligent information processing of medicinal plants based on remote sensing big data, which is expected to provide references for the development of remote sensing technology in derivative application in medicinal plant resources.
药用植物的可持续利用是中医药传承的基础，而获取药用植物信息是中医药发展的依据。传统的药用植物资源调查方法主观性强、时效性差，难以对药用植物资源进行实时监测。近年来，遥感技术已成为获取药用植物信息的重要手段，该技术的应用弥补了传统方法的不足。中分辨率卫星的公开遥感数据为提取药用植物资源信息提供了契机。本研究首先介绍了遥感技术原理，总结了药用植物资源领域常用的卫星及参数，并将遥感技术的调查方法与传统方法进行了比较。其次，综述了遥感技术在药用植物种植信息提取方面的应用以及基于遥感技术提取药用植物种植结构信息的常用方法。第三，根据生境特点将研究对象分为野生和栽培药用植物，进一步分析了遥感技术在药用植物调查与监测中的应用。最后，指出了药用植物资源遥感监测中尚未解决的关键技术问题，并提出了基于遥感大数据的药用植物智能信息处理方案，以期为遥感技术在药用植物资源衍生应用中的发展提供参考。
