Abstract

Abstract

Suaeda salsa and tamarisk are the typical vegetation in Yellow River Estuary,and also a key habitat for many kinds of rare birds. Suaeda salsa and tamarix,whose landscape scale usually small,widely distributed and often mixed with each other or other vegetation or bare soil in remote sensing images,are difficult to obtain the vegetation fractional cover efficiently,thereby affecting biomass monitoring and ecological assessment. In this study,we acquired the end-members in two ways,the first is measure the vegetation spectrum through field work,and the second way is extract them from the hyperspectral remote sensing image with the SAMCC method. Then we use the two kinds of end-members in the pixel spectral un-mixing process with 5 different algorithms,which are: LUS,OSP,MF,CEM and ACE. At last we evaluate the two kinds of end-members coverage inversion capability of the salsa and Tamarix through correlation analysis with the real coverage which measured in the field work.
