| 摘 要： | 渭干-库车河三角洲绿洲是位于塔里木盆地北缘的具有典型干旱特征的绿洲。干旱地区生态环境脆弱，土壤盐渍化严重破坏了国民经济的生产和生态环境的平衡，所以对干旱区盐渍化问题进行系统的研究是非常必要的。本文采用研究区的2001年8月6日遥感图像进行K-L和K-T变换，经过一系列波段结合．我们得到TM3、KL3、KT2波段结合是盐碱地信息提取的最佳波段结合；然后把研究区的等高线矢量图转换成DEM立体图，以及分类结果和DEM之间进行对比，结果表明，立体图的凹区和分类图的盐碱地基本重合在一起，从而我们得到导致该地区的盐渍化问题的自然和人文因素中，地形因素是占在主导地位的。 |

| Abstract: | Ugan -Kucha river delta is a typical arid land oasis which is located in the northern edge of Tarim basin. Ecoenvironment is feeble. Soil salinization is havoc for decreasing of GDP and Eco - environmental balance of arid area. Therefore it is very necessary to study systemically on soll salinization of this area. This article uses ETM image of study area to process K - L and K- T transformation, through a series of band combination we got TM3, KL3, KT2 are the best unite of extracting information of soll salinization, then contour vector graph of study area was converted into DEM, and classified image was compared with DEM. Study result indicates that deeper places of relief map fits with the salt affected are on classified image, from this we can conclude that among the factors which brings to salinization terrain is the dominant factor. |
