摘　　要：综述了高光谱遥感技术在国内外湿地研究中的应用;总结了高光谱遥感技术在湿地水质参数反演、土壤含水量反演和湿地植被精细分类等方面应用的方法研究和取得的成果;指出鉴于高光谱遥感数据自身的冗余性和信息理解程度的局限性,在湿地研究领域中仍然存在着不足之处;在此基础上,提出了高光谱遥感技术应用于湿地研究的数据多元化趋势及其在湿地类型变化动态监测、湿地生态系统的自我恢复、掌握湿地资源重新积累过程等方面的应用潜力和开发前景。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.
