///This paper introduced the development regularity of each topographic unit, and summarized some practical points combining the 1∶50 000 special investigation of Quaternary of Fuqing sheet. The practical points contain the layout method of survey line of shallow overburden, drilling density, construction technical requirements and quality control. Doing well in multi-purpose of drilling, collecting of various data completely, finding out 3D geological structure and hydrogeology and engineering conditions can provide the technical support for social economic development.
