| 摘 要： | 地下水是徐州市主要的供水水源 ,过去由于不合理开采导致了许多环境地质问题的发生。该文针对徐州市出现的这些环境问题 ,通过地质调查与水文地质条件分析 ,建立了地下水流运动方程 ,采用有限元法对地下水流进行数值模拟 ,结合地下水位观测资料对数学模型进行校正 ,然后利用校正的数学模型对现状开采条件下未来 10年内的地下水动态进行了预测 ,并对规划开采条件下地下水资源进行了综合评价 ,为徐州市水资源的合理调配和优化管理提供了科学依据

| Abstract: | Groundwater is mainly supply water resource in Xuzhou City,uncontrolled extraction of groundwater has caused many environmental geologic problems in the past. This paper is aimed at these environmental problems happened which related to water resources extraction. The equation of groundwater flow has been established through geologic investigation and analysis of hydrogeologic condition. Groundwater flow was numerical simulated using finite element method, and the model was corrected combining with observation value of groundwater level, then the groundwater regime was predicted using corrected mathematics model under the present extraction in 10 years. Groundwater resource was evaluated synthetically under the condition of planning extraction. Scientific basis was provided with rational allocation and optimize management of water resources in Xuzhou City. |
