Aquatic vegetation is an important component of wetland and coastal ecosystems, playing a key role in the ecological functions of these environments. Surveys of macrophyte communities are commonly hindered by logistic problems, and remote sensing represents a powerful alternative, allowing comprehensive assessment and monitoring. Also, many vegetation characteristics can be estimated from reflectance measurements, such as species composition, vegetation structure, biomass, and plant physiological parameters. However, proper use of these methods requires an understanding of the physical processes behind the interaction between electromagnetic radiation and vegetation, and remote sensing of aquatic plants have some particular difficulties that have to be properly addressed in order to obtain successful results. The present paper reviews the theoretical background and possible applications of remote sensing techniques to the study of aquatic vegetation.
水生植被是湿地和沿海生态系统的重要组成部分，在这些环境的生态功能中发挥着关键作用。大型植物群落调查通常受到后勤问题的阻碍，而遥感是一种强大的替代方法，能够进行全面评估和监测。此外，许多植被特征可以通过反射率测量来估算，如物种组成、植被结构、生物量和植物生理参数。然而，正确使用这些方法需要了解电磁辐射与植被相互作用背后的物理过程，并且水生植物遥感存在一些特殊困难，必须妥善解决才能获得成功结果。本文综述了遥感技术在水生植被研究中的理论背景和可能的应用。
