| Abstract: | In order to obtain the best dynamic simulation method for the Leaf Area Index(LAI) of the spring wheat in Ningxia irrigation area,the authors,based on the spring wheat LAI data observed over the land from the typical agrometeorological experiment station in Ningxia irrigating area,used the agrometeorological method and the remote sensing inverting method to simulate the dynamic changes of the LAI and then to compare the simulation accuracies of the two kinds of methods.The best simulated model for the sprin... |
