摘要

Fertility evaluation is the foundation of land management. Researching ways to evaluate productivity plays an important role in improving land and forestry management. In this paper, we propose a quantitative assessment method that evaluates soil fertility using Principal Component Analysis (PCA) and the Support Vector Machine (SVM). The PCA-SVM fertility assessment method uses PCA to extract useful information (features) from soil sample data (input data). The PCA is a training algorithm that reduces the dimensionality of the data and selects useful features. The selected features by PCA are then used as input to the SVM. We present an application of the method to an appraisal of the fertility of the farmland in the Wenzhou District of Lucheng.
