【摘要】 针对森林草原浅覆盖区地质填图隐伏地质体识别问题,基于土壤对原岩成分的继承性,提出了化探特征因子传递法。该方法是利用移动窗口将研究区滑动覆盖,在每个窗口内进行因子分析并做岩性判断,进而将不同窗口内具有同一类特征因子的样品连接起来即完成对全区的岩性识别。试验表明,相比传统方法,该方法能提高隐伏地质体识别的分辨率,有利于提高填图的精确度和准确度,为化探数据辅助地质填图提供新的思路。更多还原

【Abstract】 Aiming at the hidden geological badies identification of geological mapping in the shallow coverage area of the forest and grassland,based on the inheritance of the original rock composition,a geochemical characteristic exploration factor transfer method was proposed. The method uses the moving windows to slide the research area,and performs factor analysis and lithology judgment in each window,and then connects the samples with the same type of characteristic factors in different windows to complete the lithology identification of the whole area. Experiments show that compared with the traditional method,this method can improve the resolution of concealed geological body identification,which is beneficial to improve the accuracy and accuracy of mapping,and provide new ideas for geochemical mapping to assist geological mapping.更多还原
