Forest loud classification is currently an important issue in Taiwan forest management. To achieve a reasonable classification, establishing enough forest information and applying Geographic Information System (GIS) technique plays an important rote. This study was to investigate the feasibility of applying GIS technique in forest land classification of Lukuei experimental forest. The objective was to establish a forest land classification system which is suitable to Taiwan forest. The research content includes the establishment of basic forest information, data analysis, and the completeness of forest land classification by using GIS technique and multivariate statistical analysis. Finally, some suggestations are proposed.
