编制综合水文地质图时,经常遇到多层结构含水组的表示方法问题,特别是第四系沉积比较厚、结构比较复杂的水文地质单元,以及许多山前冲、洪积扇分布较广的地区,地下水含水组常呈多层结构。被第四系覆盖或埋藏于其他地层下的岩溶水发育的地区,也存在多层结构含水组,都需要正确地反映它们的分布特征、和赋存条件。研究多层结构含水组的表示方法,具有一定的现实意义。
In the process of compiling comprehensive hydrogeological maps, problems of representation of multi-layer aquifers are often encountered, especially the hydrologic units with relatively thick Quaternary sediments and complex structures, as well as a large number of prehistoric and alluvial fans Regions and groundwater aquifers are often multi-layered structures. Regions covered by the Quaternary or covered by karst water under other formations also have multi-layered aquifers that need to correctly reflect their distributional characteristics and the conditions for their occurrence. It is of practical significance to study the representation method of multi-layer aquifer.
