Development of intelligent spatial decision support system and application in intensive forest farm.

Fundamental data are very important in highly intensive management of forest farms in urban forest. These data can provide spatial information with precision position for management, production, planning and decision_making. Based on these, this paper puts forward the concept, characteristics and connotation of intelligent spatial decision support system (ISDSS), and the system framework and technical realization of ISDSS are studied and developed. On the basis of the geographic spatial database, a new intelligent spatial decision model was established by using the theories and methods of knowledge_discovered from database (KDD) technique, knowledge representation based on rules, uncertain reasoning based on reliability theory in expert system and optimizing multi_objectives decision_making. Also, with an instance of forest site analysis and decision_making in Beijing area, the models and algorithms were tested and applied. The results show that the spatial decision_making support system based on GIS spatial database and artificial intelligence has extensive application in precision forestry.
