摘要
以肥城市矿区为研究区,利用1986、1990、1995、2000、2005和2006年6期卫星遥感TM图像和地形图,基于ENVI技术,经过图像预处理、影像目视、计算机监督分类和人机交互的解译方法,编制了对应时期肥城市煤矿区土地利用现状图,并通过面积统计综合分析了各土地利用类型的动态变化特征。研究结果表明:林地被大量占用,到2006年已不足1986年的1/10,被开发为耕地、园地及工矿用地。工矿用地则是1986年的2倍多,且煤矿区一旦形成就难以逆转,肥城市的矿区环境已遭到破坏——地面出现了严重的塌陷。
Using six Landsat TM images and relief maps of Feicheng mining districts in 1986,1990,1995,2000,2005 and 2006,this paper obtained the land use status maps of Feicheng coal mine districts in each period based on the technologies of ENVI and computer,and comprehensively analyzed the dynamic characteristics of utilization of different types of lands through the area statistics.The results showed that a large amount of forest land was impropriated and opened up to arable land,garden plot and mining land.The area of forest land in 2006 was less than one tenth of that in 1986.However,the area of mining land in 2006 was over twice as many as that in 1986,and the reversion of the coal mine districts was difficult once they were structured.The environment of coal mine districts in Feicheng city has been destroyed——there are serious subsidence regions.
