  3. It is discovered that the correlation between msavi ( modified soil adjusted vegetation index ) and vegetation coverage is higher than that between ndvi ( normalized differential vegetation index ) and grassland coverage when the land cover is low. so msavi can be used as the main index of grassland desertification degree. in order to evaluate the precision of the result, different methods such as supervised classification, unsupervised classification and visual interpretation on image are tried respectively

    本文將其作為草地沙化的分級指標,直接通過計算分級,建立msavi等級與草地沙化程度的對應關系,確定草地沙化的程度,然後將msavl分類結果分別與目視解譯、監督、非監督分類的結果進行了精度比較,其精度高於監督與非監督分類,與典型區現場繪制和目視解譯結果的誤差為5 . 9 ,能滿足草地沙化監測實際應用要求。
