| Abstract: | Firstly, the farmland waterlogging features are introduced. Secondly, according to the monitoring theory, the main methods both in China and abroad are divided into three categories, which are surface indication method, underground water level inversion method and synthesized analysis method combined with non-remote sensing methods. Furthermore, the theory, technology, applicability, advantages and disadvantages of different methods are discussed respectively. All methods are found to be useful to monitor farmland waterlogging in different circumstance ,with defects and limitations. Finally, a summary is made. And two potential remote sensing monitoring methods for monitoring farmland waterlogging are proposed,which are soil moisture indication method and hyperspectral remote sensing method. |
