摘要: Ecosystem management has become the mainstream of contemporary forestry. Ecosystem management involves a variety of different issues and is an adaptive management approach that is able to adapt to temporal changes in needs. Therefore, a computer is needed to process complex data, and to integrate knowledge of various disciplines in order to develop decision support system for use in decision making for forestry. EMDS (Ecosystem Management Decision Support) is a decision support system for ecosystem management developed by the USDA Forest Service. The system integrates knowledge-based ecological and geographic database with geographic information system to build a dynamic decision support system that allows the user to easily modify the size of study area and criteria for assessment. Taiwania (Taiwania cryptomerioides), distributed in mid-elevation areas, is one of the most important native coniferous species in Taiwan. This species is worthwhile planting because it grows well and rarely gets infected with disease. In this research, the Luikuei Experimental Forest was selected as the study site. Using the topographic and soil data, suitable sites for Taiwania were selected according to the fuzzy logic provided by the EMDS knowledge base. It is expected to improve the traditional map overlaying method, which has the drawback of being not objective when determining the levels for suitability analysis. The results will be used as reference for the forest managers to select tree species for plantation.
