根据大量的裂隙统计、水动态资料及时间序列分析，对贵州普定后寨地下河流域地下含水空间结构特征进行了讨论。结果表明在研究区的不同地段，其喀斯特的发育程度、地下空间类型和组合有明显的差异。据此把研究区划为五个不同的地下空间结构地块单元。在流域的上游地区，表现为管道结构和快速径流地带，储蓄和调节能力差，以与地表垂直的垂直管道—溶道双重介质为主。下游地区表现为网状裂隙＿管道型的含水空间结构，储存效应和调节能力强，主要的储水空间为溶隙。中游地段则属两者的过渡类型
Based on a large number of fracture statistics, hydrodynamic data and time series analysis, the underground aquifer spatial structure characteristics of the Houzhai subterranean basin in Puding County, Guizhou Province are discussed. The results showed that there were significant differences in karst development, underground space types and combinations in different locations in the study area. Accordingly, the study is divided into five different units of underground space structure. In the upper reaches of the river basin, the pipeline structure and rapid runoff zone show a poor ability of saving and regulating, and are dominated by the vertical pipeline, the vertical dissolving medium, which is perpendicular to the surface. The downstream area is characterized by a network-like fractured aquifer structure with a strong storage and regulation capacity and a predominant reservoir space. The middle reaches of the section is a transitional type between the two
