数据挖掘在大方县土地规划应用中的探索

The Research of Data Mining in Land Planning Application of Dafang

土地利用结构变化系统是一个复杂的非线性不确定动态系统,难以利用精确的数学模型来表达。数据挖掘是一种新的从海量数据中进行知识发现的方法,大方县在土地利用规划中利用这个方法较好地预测了非线性条件下土地利用面积,预测结果基本符合大方县社会经济发展战略规划,并为新一轮土地利用总体规划修编工作提供科学依据。

Land-use structure changes system is a complicated non-linear uncertain dynamic system which couldnot be expressed through exact mathematical model. Date Mining is a new method which can find knowledge based on lots of data. Dafang County uses this method to forecast the land-use area in non-linear situation in land-use planning. The result mainly coincides with Dafang＇s strategic planning of social economic development and support scientific proof to new revision of the overall land-use planning.
