Modeling of Biology Catastrophe Prediction in Intelligent Agriculture

The pest catastrophe prediction in ecology catastrophe is one of important part in expert system of intelligence agriculture for prevent and control pest catastrophe occurrence efficiently. The paper introduces the basic principles and methods of current catastrophe prediction in ecology. By modeling for the dynamic process of population, up-grown and amount of spawn, the paper finds out the trigger point and critical value, inducing the pest catastrophe and implements the catastrophe prediction of cnaphalocrosis medinalis guenee before catastrophe to prevent big population coming into being.
