摘要
黔西南高原台面裸露着大面积的三叠系白云岩,含水介质多为溶孔、溶隙,地下水埋藏浅,岩溶水赋存较均匀,富水性强,是研究区内重要水源。本文利用区内岩溶泉流量观测数据,采用地质统计和相关分析相结合的方法,对区内地下水年际、年间的时空变化特征进行总结,研究结果表明:黔西南高原台面在岩溶含水介质组合类型、地形地貌、断裂构造和水动力特征等条件控制下,区内岩溶水流量动态呈现出平面分带、垂向分层现象,靠近中部分水岭和南面地形深切区,岩溶水流量动态越不稳定。对区内岩溶水时空分布特征的研究,为同类岩溶山区岩含水层水文地质的研究工作提供基础依据。
A large area of Triassic dolomite is exposed on the mesa plateau in southwestern Guizhou Province.Most of the aqueous media are dissolved pores and dissolved voids.The buried underground water is shallow.Karst water is well-distributed and water-rich.It is an important water source in the study area.Based on the observation data of karst springs in the area and the combination of geostatistics and correlation analysis,this paper summarizes the spatial and temporal variations of the groundwater in the region during and after the year.The results show that：,Topography and geomorphology,fault structure and hydrodynamic characteristics,the karst water flux in the area shows a dynamic zonation and vertical stratification.Close to the middle watershed and the deep terrain in the south,the karst water flow is more unstable.The research on temporal and spatial distribution of karst water in the area provides the basis for the research on hydrogeology of rock aquifer in similar karst mountainous areas.
