| 中文摘要: |
| 结合近年来在渝东南渝东北岩溶地区实施的1∶5万水文地质调查及供水示范项目,对该区岩溶地下水富集影响因素开展研究,在理论分析的基础上,统计了不同影响因素下的暗河、大泉数量及成井率。结果表明:地层岩性是岩溶地下水赋存的基本条件；地质构造是制约岩溶大泉及暗河形成、分布和径流的主控因素；地形地貌是岩溶地下水地域分异的重要条件,新构造运动为地下水的径流和溶蚀作用提供了动力条件,控制了岩溶发育的分带和成层性,这些因素共同影响岩溶地下水的富集。 |

| In combination of the recent implementation of 1∶50 000 scale hydrogeological investigation and water-supply demonstration project in southeastern and northeastern Chongqing karst area, enrichment-influencing factors for the karst groundwater are studied. On the basis of theoretical analysis, statistics of the different influence factors of the underground rivers, numbers of big springs and well completion rate are conducted. The results showed that the strata lithology is the basic condition of the karst groundwater enrichment, geological structure is main control factor of the formation, distribution and runoff of the karst big spring and underground rivers. The topography and landscape are the important conditions of the karst groundwater in the regional differentiation. New tectonic movement provides dynamic conditions for groundwater runoff and dissolution, and controls of the development zone and a layer of karst. These factors work together and influence the enrichment of the karst groundwater. |
