摘要: A non-linear transition function (Lorentzian cumulative function) best represented the relationship between leaf area index (LAI) and spectral vegetation indices (SVI) calculated from a Landsat ETM+ image tropical moist forest. The three parameters of (transition height, center half-width) describe sensitivity to range LAI values. From SVIs tested, Modified Single Ratio (MSR) had in this environment being sensitive changes 0.0-4.7.
