The best fitted VI-LAI relationships and their statistics.

Note: STDV is the standard deviation of each VI corresponding to the whole range of measured LAI. (VImax–VImin) is the difference between the maximum and minimum value of each VI corresponding to the whole range of measured LAI. The last column gives the normalized RMSE (i.e., RMSE/(VImax–VImin)) for each VI. Values in bold font indicate high performance.注：STDV为对应于实测叶面积指数（Leaf Area Index，简称LAI）全量程的各植被指数（Vegetation Index，简称VI）的标准差。(VImax–VImin) 为对应于实测LAI全量程的各VI的最大值与最小值之差。最后一列给出了各VI的归一化均方根误差，即均方根误差（Root Mean Square Error，简称RMSE）与(VImax–VImin)的比值，其中以粗体标注的数值代表性能优异。
