doi:10.13466/j.cnki.lyzygl.2015.01.020

Abstract

Abstract: The Ebinur Lake Basin is representative of the desert areas,which is not only the cross area of the central Asian flora and mongolia flora,but also is the key area indicating desert environment change of the Junggar Basin.Selecting Ebinur Lake Basin as the study area,we measured reflectance spectra of tamarix ramosissima and nitraria,caragana,haloxylon and other typical desert vegetation by the AvaField-3 portable hyperspectral spectral instrument.Through analyzing the reflectance spectra by original spectra analysis,first-order derivative analysis on red edge and envelope remove analysis,we found red edge of desert plants position is close to the long wave direction and reflectance of desert vegetation is lower.In addition,because of the significant differences,the bands of 490～510nm,540～560nm,670～690nm,680～750nm,1100～1140nm can be regarded a as the bands for identification of various desert plants.

Key words: desert vegetation, reflection spectra, first-order derivative analysis, envelope remove analysis
