The results show that the vegetation is the best in June and July during 1998-2002 and this period is shifted to July and August during 2002-2006. This shift is caused by a redistribution of water resources in the Heihe River, and an adjustment of industrial structure in Zhangye city, which is followed by a decrease of the area of summer crops, and an increase of the area of autumn crops. The yearly maximum NDVI is on the whole improved, but the trend of change of monthly maximum NDVI sees a great difference among different months. The change during the adjacent two years of both the yearly maximum NDVI and the monthly maximum NDVI witnesses a great difference, and the vegetation degradation and improvement appear fluctuantly. The major changes occur in well-developed region with the artificial vegetation, while the minor changes are in the no-vegetative or partially vegetative desert or the Gobi., authors=null,

highlight=null, articleAbstract=以1998-2006年9 a的315景逐旬的SPOT-VEGETATION数据为主要数据源，利用趋势、差值等方法，分析了张掖盆地植被覆盖动态变化的时空特征。结果表明张掖盆地植被年内变化趋势中，峰值由1998-2001年的6、7月份推移到2002-2006年的7、8月份，这与黑河分水、张掖地区调整种植结构、夏禾作物种植面积减少、秋禾增加有关；1998-2006年间，年最大化归一化植被指数(Normalized Difference Vegetation Index，NDVI)整体呈变好的趋势，但是月最大化NDVI的年际变化趋势在不同月份存在很大差异；年最大化NDVI与月最大化NDVI在每相邻两年间的变化均存在很大差异，植被退化与改善波动出现；年际间植被变化幅度大的区域均分布在人工植被发育的走廊平原，而变化幅度小的区域则分布在无植被或少植被的戈壁沙漠。,
