摘　　要：基于徐州市地下水开发利用现状,分析地下水埋深特征,结合徐州市近10年降水量、地下水开采量和承压地下水水位埋深资料,运用数理统计和曲线拟合等方法,分析降水量和地下水开采量与地下水埋深变化的影响程度及相关关系。结果表明,徐州市承压地下水埋深整体呈上升态势,承压地下水埋深变化与降水量和开采量均有关系,与降水量呈负相关,与地下水开采量呈正相关,地下水开采是造成地下水埋深变化的主要因素,影响程度大于降水量。通过探求承压地下水动态规律,为徐州市地下水资源利用与保护提供科学依据。Based on the current situation of groundwater development and utilization in Xuzhou City,the characteristics of groundwater burial depth were analyzed,and combined with the precipitation,exploitation and groundwater level burial depth data of Xuzhou City in recent 10 years,the influence degree and correlation between precipitation,groundwater exploitation and confined groundwater burial depth were analyzed by mathematical statistics and curve fitting methods.The results show that the burial depth of confined groundwater in Xuzhou city is on the rise as a whole,and the change of burial depth of confined groundwater is related to both precipitation and exploitation,and is negatively related to precipitation,but positively related to exploitation.Groundwater exploitation is the main factor causing the change of groundwater burial depth,and its influence degree is greater than that of precipitation.By exploring the dynamic law of confined groundwater,it provides scientific basis for the utilization and protection of groundwater resources in Xuzhou City.
