一、研究的目的与意义凡具有一定数量和质量,可供开采作为生活和生产用水的地下水水源,便可称为地下水资源。在支配地下水资源分布的各种自然历史条件中,新构造运动起了控制性的作用。就全世界范围来说,新构造运动在大多数地区表现为断裂活动,仅局部地区有褶绉作用、岩浆活动和火山喷发。在我国,新构造断裂常为两组不同规模和不同性质的扭性断裂,二者相互交替、相互转化、相互改 First, the purpose and significance of the research Where there is a certain amount and quality of groundwater available for exploitation as a living and production of water, can be referred to as groundwater resources. Neo-tectonic movements played a controlling role in various natural and historical conditions governing the distribution of groundwater resources. In all parts of the world, the Neotectonic movement is characterized by faulting in most areas, folds in some areas, magmatic activity and volcanic eruptions. In our country, the neotectonic faults are often two sets of torsional faults of different scales and of different nature, which alternate with each other and transform into each other
