利用监督分类、NDVI指数等遥感影像处理方法,在大同盆地桑干河流域开展了土壤盐碱地分布及盐渍化程度的应用研究。基于Landsat卫星影像,依据NDVI指数推断了盐碱土壤的分布,与第二次土壤普查和实地调查的结果进行了比较。结果表明,遥感信息技术可以宏观、动态地有效反映出盐碱地的分布及盐渍化程度。
利用鑑督分類、NDVI指數等遙感影像處理方法,在大同盆地桑榦河流域開展瞭土壤鹽堿地分佈及鹽漬化程度的應用研究。基于Landsat衛星影像,依據NDVI指數推斷瞭鹽堿土壤的分佈,與第二次土壤普查和實地調查的結果進行瞭比較。結果錶明,遙感信息技術可以宏觀、動態地有效反映齣鹽堿地的分佈及鹽漬化程度。

The distribution of saline-alkali soil and the degree of salinity were investigated in the Sanggan River Valley of Datong Basin by the remote sensing image processing methods,such as the supervised classification,NDVI index,etc. The distribution of saline-alkali soil was indicated based on the image of Landsat and NDVI index,and the results were compared with the second soil census and the filed survey. The results showed that the distribution and salinization degree of saline-alkali soil could be reflected dynamically with macroscopic scale by remote sensing information technology.
