Abstract

Abstract: Combining with the recent implementation in Chongqing Southeast and Northeast karst area of 1∶50 000 hydrogeological investigation and water demonstration project, karst groundwater enrichment characteristicswas studied, The influence degree of formation lithology, topography, geological structure and physiographic stages on karst groundwater enrichment; karst groudwater had uneven distribution of time and space. According to different stratum, topography, geological structure conditions, karst groundwater was divided into three types: extremely inhomogeneity, inhomogeneity, relatively uniform. According to karst groundwater circulation conditions and hydrodynamic characteristics, the study area of the water rich block was divided into confluence type, shunt type, discharge type, fractured type.The direction of developing and utilizing was proposed, and the basis for the development and utilization of karst waterwas provided .

Key words: environment engineering, Chongqing southeast and northeast, karst water, enrichment characteristics, inhomogeneity, enrichment model

摘要： 结合近年来在渝东南渝东北岩溶地区实施的1∶50 000水文地质调查及供水示范项目，对该区岩溶地下水富集特征开展研究。分析了地层岩性、地形地貌、地质构造、地文期等因素对岩溶地下水富集的影响程度；岩溶地下水时空分布不均，依据地层、地形地貌、地质构造条件不同，将岩溶地下水富集均一性分为极不均一、不均一、相对均一3类；根据岩溶地下水循环条件和水动力特征，将研究区内的富水模式分为汇流型、分流型、泄流型、断裂带型，提出了开发利用方向，为岩溶水的开发利用提供了依据。
