根据资料对南宁市地下水化学场进行区域划分 ,并研究了化学类型、组分、含量的变化特征与规律。从工程的角度进行分析后 ,认为水化学场变化的同时也改变了城市建筑的基础——岩土体的性质 ;而导致这些改变的主要因素是人为抽水和污染 Based on the data, the area of ​​groundwater chemical field in Nanning was divided and the variation characteristics and laws of chemical types, components and contents were studied. From an engineering point of view, it is believed that changes in the hydration field have also changed the basis of urban architecture - the nature of rock and soil; the main contributors to these changes are anthropogenic pumping and pollution
