In this paper, we distilled FVC (Fractional Vegetation Cover) image from successive NOAA/AVHRR data (1982-2000) and used method of dividing area to remote sensing image, displayed the continuate curve of area change of every vegetation type in different region, analyzed the reason of vegetation change in arid land of China west. The results showed that there are different characteristics in different regions. In North Xinjiang, desert decreased, forest increased, and vegetation improved; In Qaidam high basin, desert increased, meadow decreased, and vegetation degraded; In plain, desert is stable, oasis continually extended in Xinjiang, ecotone (middle and high grassland cover) deflated, the human activity was one of most important factors of vegetation types changing in arid lands in China Western

NOAA/AVHRR数据中提取的植被覆盖度指数,按不同植被覆盖度的指标,采用分区分类法对中国西部干旱区进行了分类,得到植被分类结果图,提取了各类植被在每个年度的面积数据,显示了各类植被面积变化的过程,并初步分析了原因。结果表明,近20年来,干旱区各区域相同植被类型的变化状况不完全相同,具有不同的特点;北疆地区无植被覆盖类型面积明显减少,生态环境有所改善;南北疆在绿洲面积增加的同时,中、高覆盖度植被减少,即在绿洲与沙漠之间的过渡带植被面积减少,柴达木盆地荒漠面积增加,森林、草甸类植被面积减少,表现出该区域生态环境退化。综合各区各类植被的变化来看,在平原区荒漠无植被区是稳定的(与其总面积相比),绿洲也是西部干旱区较稳定的植被类型,而且是不断扩大的植被类型。人类活动已是西部干旱区、平原地区植被类型发生显著变化的重要因素,而在这二者之间的过渡带类型的植被,尤其是中、高覆盖度植被的面积在减少。,
