西藏扎布耶盐湖氧化硼含量空间分布遥感研究

REMOTE SENING RESEARCH ON THE SPATIAL DISTRIBUTION OF BORIC ANHYDRIDE IN THE ZHABUYE SALT LAKE OF TIBET

利用Landsat-7多波段数据和氧化硼含量实测数据,在对数据进行预处理、波谱分析及相关分析等基础上,采用比值增强、主成分分析及彩色密度分割等处理方法,对浓度高、成分复杂的扎布耶盐湖氧化硼含量的空间分布进行了研究,揭示了扎布耶盐湖氧化硼含量的空间分布规律。

With the help of multispectral data collected by Landsat - 7 and the in situ data collection and on the basis of the preprocessing of the remote sensing data and the spectral and correlation analysis of data, the authors made an analysis of the boric anhydride content of the Zhabuye salt lake, which has a high concentration of boric anhydride and complex components, as evidenced by the results obtained by such methods as ratio enhancement, principal components and density slice. It is found that there exists spatial distribution regularity gove.rning the boric anhydride content of the Zhabuye salt lake.
