摘　　要：基于青岛市区2005年4月和2015年4月的TM影像,利用ENVI中监督分类法,结合人工目视解译,得出2005年和2015年青岛市区土地利用类型分布情况。利用土地利用类型动态模型,分析了10年间青岛市土地利用类型的变化规律。认为2005—2015年,青岛市土地利用类型产生了较大的变化,建设用地、耕地、水面、草地、林地的面积变化显著。其中,建设用地面积增加200.98 km^2;耕地面积减少105.89 km^2;水面面积减少76.68 km^2;草地面积减少69.53 km^2;林地面积增加54.45 km^2;未利用土地面积减少。说明青岛市区处于土地利用发展的时期,政府应该注重土地资源的合理利用。Based on TM images in April ol 2005 and 2015, by using supervised classification of the ENVI software and artificial visual interpretation, distribution ol land use types in Qingdao City in 2005 and 2015 have been gained. By using dynamic model ol land use types, change rule ol land use types in ten years have been analyzed.It is regarded that land use types have been changed a lot , and the areas of construction using land, arable land,water, grassland and woodland changed obviously. Among them, the area of construction using land has increased 200.98km^2; the area ol larmland has reduced 105.89km^2; the area of water has reduced 76.68km^2; grassland has reduced 69.53km^2; lorestland has increased 54.45km^2; the area ol unused land has reduced, and the degree of land use has become greater year by year, which indicates that Qingdao City is in the period of the development of land use. The government should pay more attention to reasonable use of land resources. The research results will be of most importance for reasonable land utilization in this region.
