水生植被是湿地和海岸生态系统的重要组成部分，在湿地和海岸生态系统的生态功能中起着关键作用。对大型植物群落的调查通常受到后勤问题的阻碍，而遥感是一种强有力的替代方法，可以进行全面的评估和监测。此外，许多植被特征可以通过反射率测量来估计，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，水生植物的遥感有一些特殊的困难，必须适当解决，才能获得成功的结果。本文综述了遥感技术在水生植被研究中的理论背景和应用前景。
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.
