摘  要：
【目的】利用高分辨率Quick Bird影像,并结合实地的植被和土地类型调查,对艾比湖地区阿其克苏河植被覆盖进行归一化植被指数(NDVI)遥感分类,利用遥感影像处理软件(如Envi软件、Arcgis软件、Erdas软件)提取了该区的植被覆盖等信息。【方法】基于NDVI图对该区进行植被覆盖度反演,并结合实际测量数据提出了荒漠区NDVI分类标准和植被覆盖等级划分标准。【结果】通过NDVI分类图和植被等级覆盖图,发现该地区植被大多集中于河滩及其两岸;而且离水源越近,植被覆盖度越高,NDVI值也越高,这与荒漠区植被分布特点吻合。【结论】植被覆盖度反演结果与实地测量对比分析有很好的切合度。

摘  要：
【Objective】 In this paper,the classification of vegetation coverage in Aqikesu River Basin in the Ebinur Lake region was done based on the high resolution multi-spectral Quick Bird image and the field investigation.Some software such as Envi,Arcgis and Erdas were used to pick up the vegetation coverage information and something else.【Method】Retrieval of vegetation coverage was done based on NDVI image in this study area.Classification criteria on both NDVI and vegetation coverage in desert area was proposed in this study.Judging from the classified image on NDVI and vegetation coverage,it's easy to discover that the vegetation basically grows well along the river in this study area.【Result】Both of the vegetation coverage index and the NDVI index are higher when it's closer to the water,which coincides with the vegetation distribution in deserted areas.【Conclusion】The results of vegetation coverage retrieval is fitted well with the field-measured ones.
