A STUDY ON MODELLING WINTER WHEAT YIELD OF LARGE AREA USING REMOTELY SENSED INFORMATION
大面积小麦遥感估产模型的构建与调试方法的研究

This paper centers on development and calibration of winter wheat yield remote sensing model. After analysing the requirement of necessity for wheat growth such as sun light, temperature, water and fertilizer, we developed a winter wheat yield remote sensing model for large area based bn vegetation index,temperature change rate, greenness change rate, etc. To meet the requirement of operational system for estimating winter wheat production of large area using remotely sensed information, we developed several novel techniques in variable acquirement and model calibration.
