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.
