摘要

[目的

]

研究敦煌市沙漠化动态变化特征

为敦煌市沙漠化防治和文物保护工作提供理论依据。[方法

]

基于遥感和GIS技术

选取2004和2009年的TM和ETM遥感数据进行调查判读。[结果

]

敦煌市沙漠化土地面积为1.97×10

占土地总面积的73.8%;研究期内沙漠化土地总面积减少9 102.59 hm

年变化率-0.001%;极重度沙漠化向重度、中度和轻度沙漠化转变

沙漠化程度整体减轻。[结论

]

研究区植被盖度有所好转

沙漠化程度在减缓

但土地沙漠化趋势尚未根本改变

防沙治沙仍是敦煌市的长期任务。

Abstract

[Objective] Studying the dynamic change of desertification in Dunhuang City in order to provide a support for desertification prevention and cultural relics protection. [Methods] Based on the remote sensing data and geographic information system

the TM and ETM images were determined by field investigation and man-machine interactive interpretation. Aerial land desertification information of Dunhuang City from 2004 to 2009 were extracted. [Results] There were 1.97×106 hm2 desertification land in the whole city

covered 73.8% of the total land area. The total desertification land was reduced about 9 102.59 hm2 during the study period

the annual decrease ratio is -0.001%.Very severe desertification lands reversed to severe

moderate and light desertification land. The desertification was alleviated largely. [Conclusion] Vegetation coverage is improved in the study area

which made the desertification slowed down and reversed

but desertification had not been fundamentally changed

desertification prevention will still be a long-term task for Dunhuang City.
