| 摘 要： | 试验采用2000年和2006年的CBERS一1影像数据,通过归一化植被指数(NDⅥ)计算,分析比较输水前后塔里木河流域上游地区植被覆盖度及植被类型面积的变化,结果表明:生态输水后该地区的植被盖度总体呈现上升趋势,但部分草地、林地、灌丛被开垦为农田。

| Abstract: | Test used CBERS-1 data,analyzed and compared the vegetation coverage and relevant area of the upper reaches of Tarim River through calculating NDVI（Normalized Difference Vegetation Index）,Result indicated： In all after-irrigating vegetation coverage and the relevant vegetation types area increased in this area,but part of the grassland、woodland and shrub were changed into farming land. |
