卫宁北山中卫工业园以北地区遥感解译与地热资源预测

Remote Sensing Image Interpretation and Geothermal Resources Forecasting on the North of Zhongwei Industrial Park

分别采用多源影像的图像融合与图像增强技术、大气校正法、主成分分析法对卫宁北山中卫工业园以北地区进行了地质特征的解译、地表温度和蚀变信息的提取,并综合地层、构造、地表温度、蚀变信息组合特征开展了地热资源预测。结果表明,划分的4处靶区均具地质可解释性。

Image fusion and enhancement technology on multi-source images, atmospheric correction method and principal component analysis method are used to interpret the geological features and to extract the surface temperature and alteration information on the north of Zhongwei Industrial Park. Geothermal resource prediction is carried out based on the combination characteristics of stratum, structure, surface temperature and alteration information. The results show that the four target areas are geologically interpretable.
