Evolution of Karst Groundwater Flow Field in Xingtai Baiquan Spring
摘要
Abstract
In order to explore the evolution of karst groundwater flow field in Xingtai Baiquan spring,based on the research results of predecessors for many years and the long-term monitoring data of relevant departments,the variation characteristics of groundwater level and flow field in karst water system in spring in recent 50 years were summarized.The results show that the karst water system has experienced three main stages:the natural state before 1980s,the gradual decline of groundwater level from 1980s to 2015,and the gradual rise of groundwater level after 2016.Correspondingly,karst groundwater flow field has experienced three main stages:natural state,flow field differentiation and flow field recovery.The further study shows that the direct factor driving the evolution of karst groundwater field is the imbalance of replenishment caused by the change of recharge and discharge terms.Since 1980s,groundwater funnels caused by continuous overexploitation drive the differentiation of karst groundwater flow field.Since 2016,the displacement and pressure extraction of karst groundwater by river water diverted from the South-to-North Water Diversion Project has dominated the recovery of karst groundwater flow field and the rise of groundwater level.关键词
