Abstract:
The present invention relates to a method for optimally improving a surface water simulation for physics options by using a micro genetic algorithm of a genetic algorithm in a Noah multi-physics options model. The present invention not only improves the accuracy of the model but also maximizes the accuracy of the model in a wide target area for water variables with large deviation according to the difference of a coating state and surface soil like evapotranspiration and runoff.

Abstract:
According to the present invention, an annual vegetation predicting method includes: a step of separately analyzing a correlation between a plurality of meteorological factors and the main ingredients of a plant activity phase mode (PM) and a plant activity intensity mode (AM) which are disassembled from the past vegetation index through an empirical orthogonal function analyzing method; a step of separately selecting at least one predictive meteorological factor determined to have a statistically meaningful correlation among the meteorological factors based on the correlative analysis of each prediction of plant activity intensity and plant activity phase; and a step of separately predicting the plant activity intensity and the plant activity phase based on the past data relating to the plant activity intensity and the plant activity phase, and the present and past data for the selected prediction meteorological factor.
