Abstract:

C5.0 Decision Tree is capable of discovering structural information in data,and building tree intuitively and intelligibly,thus it can be used to obtain transformation rules of cellular automata(CA).In this paper,we gave out a CA Model based on C5.0 Decision Tree,analyzed theories and principles,and buildup method of this kind of models.And then,taking city land use change of Hangzhou City as a case,we got land use change rules from historical land use data and its factors by using C5.0 Decision Tree.Combining this rules and CA model,we simulated and predicted land use changes in Hangzhou City.Results show:(1)by C5.0 Decision Tree,we could get more accurate rules under lower sampling rate;(2)comparing with other rulesgetting methods,rules are clear and explicit in C5.0 Decision Tree,so it’s suitable to get CA rules;(3)we could get higher accuracy and more reliable result by using land use change CA Model based on C5.0 to simulate land use change.
