以烟台市1989、1996和2002年3期TM遥感影像为基础，对经过MNF变换后的影像采用面向对象分类方法提取了烟台市土地利用类型信息，研究了烟台市土地利用的总量变化特征和土地利用类型动态变化特征。研究结果表明：烟台市城乡建设用地由1989年的12．4％增加为2002年的20．35％，增加了近8％，主要由农田和有林地转化而来，表明城市扩张占用耕地现象严重。通过对土地利用结构的单一和综合土地利用动态度分析，表述了烟台市土地利用动态呈现1996～2002年度的变化小于1989～1996年度变化特点，说明了当前采取一些措施的有效性。

Based on three period TM remote sensing images of Yantai city respectively in 1996.1989 and 2002, this paper exacts innformation of land use types in Yantai City from the images after MNF transform by using object-oriented classification method,and analyses the change features of land use amount and dynamic changes of land use types in Yantai City. The results show that the urban and rural construction land of Yantai City increases from 12.4 % in 1989 to 20.35 ~/0 in 2002, an increase of nearly 8 %. These construction land mainly converts from farmland and forest land,which indicating that urban expansion has seriously occupied cultivated land. Based on analysis of the simplicity of land use structure and dynamic degree of land use,it is shown that the annual variation of dynamic land use between 1996-2002 is less than that between 1989-1996,which illustrates the validitv of current measures.
