Application of Ecosystem Management Decision Support System in selecting suitable site for Taiwania

4. Discussion
Though this study shows the value of EMDS in suitability analysis, there is still some problem with respect to the analysis units. The analysis units in the resulting map are complex, and the locations and boundaries are difficult to define in real world, which may cause the work difficult. The common units must be created in order to build the database for ecosystem decision support system.
First order watershed unit and soil unit were used because the choice of species is a type of small scale ecosystem management. For incorporating the ecological issues at different scales in EMDS, all the units must be converted to match the corresponding watershed unit, which is used as the basic unit.
5. Conclusion
The following conclusions can be drawn from this study:
- It is feasible to apply EMDS in species determination in Taiwan. As for large scale forest planning, more complex factors must be considered, and more perspectives such as economics, society, must be involved.
- Topographic factors are too rough to determinate the species, because the species determination is a local forest programming. Data scale must be selected carefully to match the study issues.
