摘　　要：以江苏港口、泰县、张甸公社、泰兴县、生祠堂镇幅平原区1∶50000填图试点为例,围绕深覆盖平原区1∶50000基础地质填图的不同深度层次目标任务,采取多种有效技术方法组合,分别对浅表（0-4 m）沉积物、第四纪以来松散层、以及基岩地质等3个深度层次的有效地质填图技术方法进行研究。浅表采用槽型钻＋DEM＋RS的综合填图方法,第四纪以来松散层采用钻孔、综合地球物理测井相结合的方法建立地层格架,基底地质特征通过区域重磁资料结合浅层地震勘查研究,有效填绘各层次地质信息。基于多种信息源,建立了不同深度、不同精度的多尺度三维地质模型,通过三维建模客观表达多层次地质结构特征,丰富了平原区1∶50000填图成果图件体系。最后,探索了不同层次填图成果的应用领域,为平原区1∶50000填图的地质图件表达及成果应用提供示范。To take geological survey of 1 ∶ 50000 sheets of Gangkou,Taixian,Zhangdiangongshe,Taixingxian and Shengcitangzhen for an example,geological mapping technologies for three depth levels of shallow（ 0 to 4 m）,Quaternary and bedrock depth have been discussed in this paper.Different combination of effective mapping methods should be selected to determine different mapping targets of different depths. Shallow deposits are mapped by the methods of groove drilling,DEM analyzing and RS（ remote sensing） image interpretation. The stratigraphic framework of Quaternary deposits is established by combination of drilling and integrated geophysical logging. The bedrock geological characteristics are studied according to the regional magnetic data combined with the shallow seismic exploration method. These geological methods could obtain geological information effectively. The multi-scale three-dimensional geological models of different depth and precision are established based on a variety of geological information. The multi-level geological structure characteristics are presented by three-dimensional modeling,which enriches 1 ∶ 50000 geological mapping results. Finally,the applications of different level mapping results are discussed,leading the way of expression and application of 1∶ 50000 geological mapping results in plane area.
