摘　　要：选用济南市1995、1998和2003年3期遥感影像,利用遥感软件图像处理模块及计算机解译模块,分别提取3期影像中的绿地、建筑用地、林地及水体信息;利用遥感软件建模模块统计分析得出济南市土地利用面积变化及转移矩阵,并得出地学信息图谱,利用地学信息图谱和转移矩阵监测与分析济南市土地利用的时空变化。结果表明,1995~1998年济南市土地利用结构变化最主要的特征是绿地向建筑用地的转化,绿地转变为建筑用地的面积为62.27 km2,占初始绿地面积的25.84%;1998年济南市城市扩张加剧导致绿地和林地减少,而随着人们环保意识的增强,2003年绿地、林地的面积逐渐增多,但仍比1995年少。The three-period（1995,1998 and 2003） remote sensing images in Jinan City,China are selected.And the information of green land,construction land,forest and water body is extracted by using the image processing module of remote-sensing software and computerized interpretation module.Both the change table and transfer matrix table of land use area are analyzed by modeling module of remote-sensing software.Then,the Geo-information Tupu is obtained;and the temporal and spatial variation of land use in Jinan City is monitored and analyzed by Geo-information Tupu and transfer matrix.Result shows that land use structure change of Jinan City in the years 1995-1998 shows a transformation from green land to construction land.Area of green land changing into construction land reaches 62.27 square kilometers,accounting for 25.84% of the initial green land.In the year 1998,area of forest and green land is reduced due to the urban expansion of Jinan City.However,with the enhancement of people＇s awareness of environmental protection,area of forest and green land gradually increases in the year 2003,which is still less than that in the year 1995.
