Fitting model includes two independent variables, namely the raw data of vegetation index, a level of decomposition and reconstruction of their data after that data of a scale. Finally, the accuracy assessment of the two simulation models to test the model using the value. 拟合的模型中包括两个自变量,一是植被指数原始数据,个其一级分解重构后的数据,即一尺度数据。最后对两个拟合模型的精度评估,检验模型的使用价值。
