摘要： 通过对1986年和2000年两期LandsatTM2,3,4波段组合影像的解译判读,揭示了14a间临泽土地利用的动态变化规律。研究表明,在河西走廊脆弱的生态环境中,临泽绿洲面积总体扩大,尤以耕地面积扩大了34%左右;而未利用土地14a中减少了0.71%;城乡工矿居民用地也有较大增长,增幅在11.39%左右。综合分析表明,人为因素在生态环境演化中起主导作用。

Abstract: Interpretation on the TM2,3,4 integrated images for 1986 and 2000 periods has showed the dynamics of land use in Linze County.In the fragile ecological environment of Linze County,the area of oasis expanded generally,especially the area of cultivated land mainly from grassland increased by 34% or so.Simultaneously,the residential area has increased about 11.39%,and the area of woodland has increased 10.90%.By contrary,the area of unused land has decreased 0.71% and grasslands have decreased 26.74% in the 14 years.The water area has also decreased 40.91%.From the analysis we can see that anthropogenic factors play the crucial role in the evolvement of the ecological environment in Linze.Key words:Linze County;land use;dynamic;Remote Sensing(RS);GIS
Key words: Linze County, land use, dynamic, Remote Sensing(RS), GIS
