摘　　要：现代沉积过程与古代环境相类似,因而地质学家将现代碳酸盐岩台地作为获得沉积物分布特征空间数据的天然实验室,通过卫星多光谱资料精确描绘和模拟现代碳酸盐岩沉积相的横向分布有助于地质学家更好地表达和理解大范围岛礁区的碳酸盐岩沉积相特征。随着遥感技术的不断发展,利用成像光谱理论进行对地观测的技术也日渐成熟。本文介绍了利用卫星多光谱资料,通过非监督分类和沉积数据校正分析法绘制相图的编图技术及在大小巴哈马礁滩的应用实践和相图。这一真实相图的产出及其全球规模的对比和分析提供了潜在经济、环境和商业的价值,并提高了油气勘探和生产的预测能力。Modern carbonate environments have been respected as natural laboratories to extract di mensional data about carbonate sediment distribution patterns, which can help geologists better explain carbonate sedimentary distribution and is critical to oil exploration and development. With the rapid development of remote sensing technology, the observation technology based on imaging spectral theory has also become mature in recent years. This paper introduces the readers to the mapping tech- nology, which is based on the satellite multi-spectrum data through non-supervised classification and sedimentary data calibration and analysis for mapping sedimentary facies, and its practical application, taking the Great and Little Bahama Banks as examples. The facies maps provide a tool for geoscientists to make global comparisons and analyses so as to improve predictive capabilities in hydrocarbon exploration and production.
