Abstract：In order to improve the healthy and sustainable development of coastal wetland ecosystem,the authors took Suaeda Salsa as investigated subject and acquired hyperspectral reflectance spectra of Suaeda Salsa and biomass data.The correlation was analyzed between biomass and reflectance spectra formation forms.The estimation models of Suaeda Salsa biomass were constructed based on those variables,which had relative higher relationship with biomass of Suaeda Salsa.The results indicated that the coefficient was the greatest between biomass and the variable named as (R800-R635)/(R800 + R635),and that the precision of estimation model based on the variable was the highest.The study will provide quantitative remote sensing technology applied in vulnerable coastal wetland ecosystem with technique support.
