西藏盐湖TM影像遥感分析

Remote Sensing Analysis of Tibetan Salt Lakes by TM Imaging

利用TM影像及数据,对西藏盐湖做了全面的分析探讨,总结了盐湖的遥感影像特征,建立了遥感解译标志,并利用不同盐度水体的反射率和主成分分析对盐湖做了遥感信息的探索性研究。以此为依据,对西藏全区盐湖进行了判读,识别出大于1km2的盐湖区392个,为以后从事西藏盐湖研究奠定了良好的基础。

Using TM imaging and data,the author(s) presented a comprehensive analysis and discussion of Tibetan salt lakes.Imaging characteristics of remote sensing of the salt lakes were summarized.And remote sensing interpretation signals were established.Also,exploring investigations were made for the remote sensing information of the salt lakes by reflectivity and major compositional analyses of waters with various salinities.Based on this,the whole area of Tibetan salt lakes was parsed,with 392 salt lakes having areas of greater than 1 km^2 identified.The job provides a good basis for future study of Tibetan salt lakes.
