通过总结南方岩溶地区水文地质环境地质综合调查和地下水开发利用示范6个方面成果,得出南方岩溶地区水文地质环境地质条件具有10个特性:岩溶发育受层组结构类型、地质构造格局和水动力条件等因素控制的综合性,岩溶地下水分布的非均一性,岩溶含水介质由孔、隙、缝、管、洞构成的多重性,岩溶地下水流运动的多相性,岩溶地下水动态变化的剧变性,岩溶水资源时间分布的季节性,干旱与洪涝的交替性,岩溶地下水污染的隐蔽性,岩溶地下水的深埋性,岩溶地下水与生态经济的相关性;论述了对碳酸盐岩层组结构类型、构造演化与岩溶发育期次、岩溶形态组合关系、表层岩溶带、岩溶地下水系统、岩溶地下河、主要环境地质问题和岩溶水资源开发利用条件8个关键科学问题调查研究的技术要点。
The karst area in South China is about 520,000 square kilometers,which is controlled by the rock properties,group structure types,geological structural framework,topography and hydrodynamic conditions.The development and distribution of karst in the area is quite uneven.The special subsurface-underground double-deck structure leads to the lack of surface water and deep buried underground water.With the influence of global climate change and irrational human activities,rocky desertification,drought and flood disasters,groundwater pollution and other major environmental geological problems have occurred in karst areas of South China.These natural and man-made factors have seriously restricted the sustainable development of regional social economy,making many karst areas become one of the poorest areas in the country.In order to promote the economic development,ecological civilization construction and poverty alleviation of the karst areas in South China,it is necessary to further clarify the karst hydrogeology and environmental geology conditions,providing a basis for the development and utilization of resources,offering water resources guarantee for the residents and economic development of areas with serious water shortage,and technical support for the protection and control of ecological environments.By summarizing the six research results on the comprehensive investigations of hydrogeology and environmental geology and groundwater development and utilization in the karst areas of South China,this study suggests 10 characteristics of hydrogeological and environmental geology conditions in karst areas of South China,which are stated below,the comprehensiveness of karst development controlled by the strata structure,geologic structure frames and hydrodynamic conditions;heterogeneity of karst groundwater distribution;multiplicity of karst water-bearing media by pores,gaps,joints,pipes and holes;multiphase characteristics of karst groundwater flow;variability of karst groundwater dynamics;seasonal distribution of ka
