| 摘 要： | 基于1989,1999年和2007年TM/ETM＋影像,从土地利用变化的视角分析巴丹吉林-腾格里沙漠间沙丘活化带的发展过程,并探讨沙丘活化带发展的驱动因素。分析表明：①1989-2007年,研究区沙地和耕地面积增加,草地、盐碱地和沼泽地面积减少,景观破碎化程度加剧,沙地斑块质心向西北偏移,即腾格里沙漠西北缘向巴丹吉林沙...

| Abstract: | The Badain Juran and Tengger deserts are ones of the three main sources of sandstorm in China.With the increasing frequency and intensity of sandstorm occurrence in China,more and more attention has been paid to the merging status of deserts in the dune-activation region(DAR for short) between the Badain Juran and Tengger deserts.Based on Landsat TM/ETM+ images in 1989,1999 and 2007 respectively,the desertification process in the DAR was investigated using the methods of dynamic change,transferred matrix an... |
