The objective of the present invention is to provide a method capable of rapidly, simply and accurately predicting the productivity of an afforestation candidate area, including the productivity of planted trees in an afforested area.The present invention provides a method for predicting the productivity of an afforestation candidate area, including (A) to (D):(A): sort soil component values and soil spectra in reference forest area by means of multivariate analysis to obtain a correlation between soil component values and soil spectrum;(B): sort productivity, topographic information and soil component values in reference forest area by means of multivariate analysis to obtain a correlation between productivity, topographic information and soil component values;(C): from the soil spectrum of the afforestation candidate area, obtain a predicted value of the soil component values on the basis of the correlation obtained in (A); and(D): obtain a predicted value of the productivity of the afforestation candidate area on the basis of the topographic information of the afforestation candidate area and either the soil component values of the afforestation candidate area or the predicted values of the soil component values obtained in (C), on the basis of the correlation obtained in (B).L'objectif de la présente invention est de fournir un procédé permettant de prédire rapidement, simplement et avec précision, la productivité d'une zone candidate de boisement, y compris la productivité d'arbres plantés dans une zone boisée. La présente invention concerne un procédé de prédiction de la productivité d'une zone candidate de boisement, consistant (A) (D) : (A) : à trier des valeurs de composantes de sol et des spectres de sol dans une zone de forêt de référence au moyen d'une analyse à variables multiples afin d'obtenir une corrélation entre des valeurs de composantes de sol et un spectre de sol ; (B) : à trier la productivité, des informations topographiques et des v
