| 摘 要： | 笔者在ENVI软件支持下,通过432波段假彩色合成方法对黄土高原经济带山西太原盆地的土地类型进行影像判读,区分出类别。利用1990年TM和2000年ETM影像对黄土高原经济带山西太原盆地影像计算NDVI值,求解植被覆盖度,通过对比,得到植被覆盖度10年间的各个土地类型上变化。

| Abstract: | This article is about to judge land covering types of Taiyuan Basin in Shanxi province,China based on compounding 4,3,2 band of TM/ETM.NDVI and vegetation covering percentage on using the image of TM in 1990,ETM in 2000 were calculated.Vegetation-covering changes in every land covering types during the decade were concluded. |
