| 摘 要： | 由于MODIS数据具有高时间分辨率、连续性好、获取成本低的特点,本文选择MODIS作为主要数据源,结合在美国地质勘探局网站下载的NOAA-NDVI数据,研究了艾比湖地区荒漠化现状及动态变化监测的方法。主要解决了MODIS数据和NOAA-NDVI荒漠化信息的提取的问题。分析了艾比湖地区近2a及近11a不同荒漠化等级的变化。艾比湖地区从2002年至2004年荒漠化趋于严重,但1993年较2004年荒漠化程度减轻,即在这11a中荒漠化程度呈现波动变化,但总体趋势呈好转迹象。

| Abstract: | Because of MODIS data shows some advantages,such as high time-resolution,better continuity and low-cost,by using MODIS satellite data as a main datum source and NOAA-NDVI data which are downloaded from www.usgs.gov,this article studied the distilled methods of desertification information from MODIS and NOAA-NDVI data.Besides,analyzed the desertification grade of Ebinur Lake area,and its varieties in recent two years and past eleven years.We found the desertification became more serious from 2002 to 2004,but compared with 1993 and 2004,meanwhile we found that desertification situations have a change with good direction during this period. |
