A Review of Application of Hyperspectral Remote Sensing to Wetland Study

Hyperspectral remote sensing data,with its advantage of high spectral resolution,has been used to invert the earth surface information. In order to understand the application of hyperspectral remote sensing to the wetland study,the paper gave a review of hyperspectral technology in national and international remote sensing of wetlands and summarized the research methods and progress results of hyperspectral remote sensing technology used in the inversion of wetland water quality parameters,the inversion of soil moisture and vegetation sophisticated classification of wetland. Then the paper pointed out that there are still the shotcomings in the application of hyperspectral remote sensing to the wetland study out of the redundancy of these data and the limitations in terms of information understanding. On this basis,the paper proposed that the application of the hyperspectral remote sensing data to wetland study will tend to diversify,and there is a great potential and application prospect in terms of the dynamical monitoring of the change in wetland type, the self-healing of wetland ecosystem and the mastering of re-accumulation process of wetland resources.
