The best fitted relationships between LAI and vegetation indices.

<p>The MAVI and three soil adjusted vegetation indices (SAVI, OSAVI, and MSAVI) are compared in the four study areas: (A) Tiantongshan, (B) Maoershan, (C) Hulunbeier, and (D) Xilinhaote. The statistics of the best fitted VI-LAI relationships are listed in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0102560#pone-0102560-t003" target="_blank">Table 3</a>. MAVI produces a higher <i>R</i>², smaller normalized RMSE of retrieved LAI compared with the three soil adjusted vegetation index in both forest and grassland areas.
