摘要
介绍了基于小波变换的反射光谱分析技术的基本理论和方法;运用此技术手段对克拉玛依市白碱滩区西侧地区40条岩石野外光谱曲线数据进行了定量处理,总结并分析了蛇绿岩套中常见典型岩石(基性混杂岩、辉长岩、橄榄岩、蛇纹石)的光谱特征及其产生原因。最后,结合ETM+波段范围提出了适用于西准噶尔地区多波段遥感影像光谱角(Spectral Angle Mapper,SAM)提取模型,从遥感影像上识别蛇绿岩分布奠定了良好的基础。
This paper is based on the wavelet transform Reflectance Spectroscopy the basic theories and methods; Then use of this technology by means of 40 rock Karamay field spectral curve for the quantitative data, summary and analysis of the ophiolite common typical rock （basic m61ange, gabbro, peridotite, Serpentine） and the spectral characteristics of the cause. Finally, with the ETM q- bands scope of the application areas in the West Junggar multi-band image and Spectral Angle Mapper （SAM） model for the remote sensing images from the identification ophiolite distribution laid a good foundation.
