Abstract: Through the two-factor variance analysis theory and the SAS statistics software,researches on space-time law of land-use structure information entropy of Fuxin city are conducted.It is found that the time change of information entropy varies slightly from 1996 to 2003,while the space changes significantly.The information entropy of Haizhou District changes most and is distinctly different from those of other areas.The information entropy of Qinghemen District and Fumeng District barely changes.
