PREPARATION METHOD OF FOREST WATER MAP USING COMPUTER PROGRAM AND THE SYSTEM

摘要

The present invention comprises the steps of: (a) measuring a volumetric moisture content according to at least two or more metric moisture tensions for a soil sample collected from a specific grid; (b) Parameters for applying the random forest model by driving the simulator program using the measured metric moisture tension and volumetric moisture content obtaining estimates of , a, n, m; (c) said parameters , estimating optimal hyperparameters of the random forest model using the estimated values of a, n, and m and input variables, and performing model learning; (d) the parameters of Equation 1 below through the learned random forest model , deriving predicted values of a, n, m; and (e) the parameter , a, n, calculating a predicted value of the volumetric moisture content for each metric moisture tension by using Equation (1) determined by the predicted values of a, n, m provides
