针对徐州市地下水长期无节制开采和管理不善而引起的多种环境地质问题 ,建立了与研究区裂隙岩溶含水层相适应的地下水流模型 ,并运用有限元方法进行求解。考虑到大气降水的多寡及其分配状况是影响地下水资源的最终决定因素 ,同时建立了研究区大气降水的时间序列模型 ,并应用于评价该区地下水资源 ,从而在宏观上为徐州市合理开采裂隙岩溶水资源提供科学依据。其结果对我国其它类似地区地下水资源的合理开采具有指导意义。
In order to solve the various environmental and geological problems caused by long-term uncontrolled exploitation and management of groundwater in Xuzhou City, a groundwater flow model suitable for the fractured karst aquifer in the study area was established and solved by finite element method. Considering that the amount of precipitation and its distribution are the final determinants of groundwater resources, the time series model of atmospheric precipitation in the study area is established and applied to evaluate the groundwater resources in this area so as to macroscopically reasonably exploit fractures Karst water resources provide a scientific basis. The result is instructive for the rational exploitation of groundwater resources in other similar areas in China.
