Study Of Applying Techniques Of Afforestation Expert System Support Gaining Knowledge Automatic

Environment and development are the most important theme in the world, forest is physical elements of human social exist and development. There are too many subjective factors in traditional afforestation. There is much ready knowledge, but it is difficult to collect and trim knowledge. In addition, a set of knowledge of one zone is usually different with another zone. In order to achieve the forestation target, it is important to change forestation mode and adopt information technique to force the development of forestation and forestry export. The background of this paper is national'863'item. This item apply network, database technique and export system technique and create forestation export system based on webThis paper introduce theory of export system and other technique at first, then analyze information technique and research the method of afforestation, the constitutes of knowledge and finally choice a system framework and environment to exploit and apply. In this item we analyze and compare many design mode of knowledge base, finally choice generational knowledge and combine database to organize knowledge base. This system is software modularity and offer some custom taglib to simplify exploit and expand system. In addition, we apply the theory of machine and create a software which could achieve append and update of knowledge through analyzing a set example data.
