A dynamic decision system of soil erosion prevention based on rough sets
Huang Jin · The Chinese Journal of Geological Hazard and Control · 2002
A dynamic decision system based on fuzzy clustering and rough set theory is designed for soil erosion prevention in the eastern area of Gansu Province.Both the dynamic classification method of soil erosion in which the co effects of many factors are considered,and the knowledge deriving method by which the classification rules are extracted from sample data are presented.Moreover,a new way to use rules of rough set,which is called the sorting prior method,is proposed.With this method,the problem of decision rule matching new data samples is well solved by arranging the condition attributes in order of their importance and sorting prior to choose the decision rules.Finally,calculating examples show that this method is effective and practical.
