| 摘 要： | 贵州遍布碳酸盐岩,这些碳酸盐岩控制了丰富的岩溶地下水分布。由于碳酸盐岩空间分布不均匀,岩溶地下水空间分布也不均匀,导致贵州岩溶山区找水的成功率较低。为了提高找水的准确率,减少经济损失,需要对贵州碳酸盐岩相与岩溶地下水的空间分布特征进行研究。本文基于资料收集和野外地质调查,运用MPGIS工具,编制了相应图件。研究结果表明,贵州碳酸盐岩相主要分布在北部、西部和南部,其中南部和西部主要为开阔台地相的石灰岩区,北部和东北部主要为局限台地相的白云岩区,西北部和西南部主要为开阔台地相石灰岩与局限台地相白云岩互层区,西南的安龙-贞丰-紫云-罗甸一带和贵阳青岩、安顺地区主要为台地边缘相礁灰岩分布区;开阔台地相石灰岩控制下的岩溶地下水为溶洞-管道水,局限台地相白云岩控制下的岩溶地下水为溶孔-溶隙水,开阔台地相与局限台地相互层控制下的岩溶地下水为溶隙-溶洞水,台地边缘相礁灰岩控制下的岩溶地下水为岩溶洞-管道水。该研究结果对贵州岩溶地下水的寻找和开发以及提高找水准确率具有重要的指导意义。

| Abstract: | Carbonate rocks are widely present in Guizhou which control the distribution of rich karst groundwater there.As the spatial distribution of these carbonate rocks is not uniform,the karst groundwater is also not uniform.Thus the efficiency of searching for the karst groundwater is low in mountainous areas of Guizhou,which can cause significant economic losses.To solve this problem,it is necessary to characterize the distributions above.By means of collecting data and field geological investigation,using MPGIS tools,this work performed mapping and analysis for this issue.The results show that the open-platform facies limestones are mainly distributed in the south and the west of Guizhou.The restricted platform facies dolomites are present in the north and northeast.The interbedded areas of limestone and dolomite appear in the northwest and south.The platform edge reef limestone characterizes the Anshun and Qingyan areas as well as around Anlong,Zhenfeng,Ziyun and Luodian of southwest Guizhou.The karst groundwater can be divided into 4 types,which are the karst cave-pipe water in the open platform limestone,dissolved pore-crack water in the restricted platform dolomite,crack -cave water in the interbedded areas and the karst cave-pipe water in the platform edge reef limestone.These research results have important guiding significance for searching for and exploitation of karst groundwater and improving the successful ratio of well drilling in the future in Guizhou. |
