There are some questions such as forest fire model selection, forest fire model updating, verifying simulation accuracy and so on in traditional forest fire spreading system. Study purpose is to build an innovative forest fire spreading simulation system based on DDDAS in this paper. The system can increase precision of forest fire spreading simulation by model base, model selection, model updating and so on. It can provide a strategic decision for forest fire save and new technologies demonstration for other related field of research. The research encompasses several major topics:(1) This paper brings up the term of dynamic data driven forest fire spreading simulation system and supplies new research approach and thought for forest fire spreading simulation study. The system framework was brought.

Many tree species at the same time and solve the spatial heterogeneity which empirical method could not achieve. Therefore, the assessment method could be applied in the selection of species for afforestation or species selection in the forest restoration areas.From collecting the attributes of planting species, spatial distribution data and environmental factors, we could integrate and analyze the data for further simulating the forest dynamics of forest in Taiwan. The impact of global change on forest also could be evaluated.

应用生育地因子评估树种之生态地位，能解决统计实证方法在空间异质性使用的限制，并可同时评估多种树种，因此可应用在造林树种之选择，亦可应用於崩塌地复育造林树种之选择，以及林相改良造林树种之选择，在收集更多树种属性与空间分布资料后，配合此评估方法，未来更可模拟出台湾森林之动态，以及评估环境变迁对台湾森林所造成的影响。
