东华理工大学毕业设计（论文） 摘要 摘 要 地下水是人类赖以生存的、不可或缺的重要资源。邢台市岩溶水资源是整个百泉水文地质单元不可分割的一部分。由于邢台市水资源短缺,地下水均衡分析是进行水资源评价和进行可持续性研究的基础。多年来邢台市地质环境监测站一直从事地下水资源环境的监测工作。本文以地下水系统理论为指导,在现有观测资料的基础上，充分收集有关水位和水量资料，对百泉泉域岩溶水水资源量进行了计算，对邢台市岩溶水资源进行了均衡分析。近十几年来，由于本区地下水开采量增加较大，此外受泉域内水利工程的兴建和气候偏干旱、大气降水偏小的影响，地下水位经历了大幅下降，本次工作通过利用近期（2006～2010年）资料对现状条件下百泉岩溶水系统的地下水补给量进行计算，五年邢台市区岩溶水亏损1.47×106m3，水位下降了28.57m，平均下降速率为5.71m，岩溶地下水处于负均衡。根据本区地下水开采量与地下水动态资料较完整性的特点，运用排泄量法计算地下水补给量。 关键词：地下水均衡； 岩溶水； 负均衡； 排泄量法； 东华理工大学毕业设计（论文） ABSTRACT ABSTRACT Groundwater is one of the important resources, and indispensable to the survival of humans. Xingtai karst water is the best spring geological unit. Because of the micro water shortage, water balance analysis is the basis of water resources evaluation and sustainability research. Xingtai geological environmental monitoring stations over the years has been engaged in the monitoring of groundwater resources and environment. Groundwater system theory as the instruction, the article on the basis of the existing observation data collected information about the water level and water adequately to calculate the spring to spring karst water resources domain, and analyzed the groundwater balance of karst water resources in xingtai. In recent years, due to large regional groundwater resources increase, moreover the springs in the domain of water conservancy project construction and small partial drought climate, atmospheric precipitation, the influence of underground water level has been a sharp decline in this work by using the data of recent (2006 ~ 2010) with the status quo under the condition of the groundwater recharge to calculate spring karst water system, karst water loss 1.47 x 106 m3 in five years in xingtai city, water levels fell by 28.57 m, the average decline rate is 5.71 m, the karst groundwater is in a negative balance. According to the integrity of the data of regional groundwater resources and groundwater, we use the discharge method to calculate the ground
