本文阐述了科学试验卫星像片的二次开发研究，计算机三维立体模拟显示及多参数特征提取的原理、方法和步骤；综合研究了伊犁盆地南缘可地浸砂岩型铀矿不同级别的远景地段在不同类型影像上的特征，分析了远景地段影像特征的内涵及地质意义，并据此对远景地段影像特征进行了识别。在此基础上，采用层层剥笋、步步深入、逐次缩小范围的方法，对伊犁盆地从区域成矿远景、有利地段（靶区）的优选到矿区范围有利勘探地段进行了逐步分级预测，取得了良好的验证效果。 This paper describes the secondary development of scientific experiment satellite imagery, computer three-dimensional simulation display and multi-parameter feature extraction principles, methods and steps; comprehensive study of the southern Ili basin can leaching sandstone-type uranium deposits at different levels of prospect Based on the characteristics of different types of images, the connotation and geological significance of the image features of the long-distance sections are analyzed, and the image features of the long-distance sections are identified accordingly. On this basis, the method of layering layers of bamboo shoots, step by step deepening, and narrowing the range step by step was adopted to classify the Yili basin from the prospect of regional metallogenetic prospect, the favorable area (target area) Have made a good verification results.
