摘要: Reed marshes, the world’s most widespread type of wetland vegetation, are undergoing major changes as a result climate and human activities. The presence or absence water in reed marshes has significant impact on whole ecosystem remains key indicator to identify effective area help estimate degree degeneration. Past studies have demonstrated use interferometric synthetic aperture radar (InSAR) map water-level for flooded reeds. However, identification different hydrological states is often poorly understood. analysis given this paper shows that L-band coherence very sensitive surface conditions beneath so it can be used classifier. A method based statistical distributions wet dry reeds using InSAR pairs was, therefore, investigated study. experimental results were validated by in-situ data showed...
