If we say that the proposition in 2006 essay "Man and the Road" study point to focus on as individuals and as the object of "Road" dialectical relationship between the 2007 composition of the proposition "Sky" focuses on the mental space to explore 2008 essay topics were focused on the excavation of the inner world, then in 2009 the title of the essay is focused on people with a symbiotic blend of the trend of the times.

如果说，2006年的命题作文&人与路&考察点侧重于作为个体的人和作为客体的&路&之间的关系辩证，2007年的命题作文&怀想天空&侧重于探究人的精神空间，2008年的作文题目侧重于人的内心世界的挖掘的话，那么2009年的作文题目则是侧重于人与时代潮流的交融共生。

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.
