| 摘要: |
| 【目的】基于落实最严格水资源管理制度的需求，提出适用于平原区浅层地下水管理控制水位的划定方法。【方法】根据濮阳市浅层地下水开采特点，在对地下水均衡法、疏干体积法、时间序列法等方法改进基础上，研究提出研究区地下水管理控制水位指标。【结果】时间序列法仅适用于地下水开发利用方式不发生较大变化的区域；地下水均衡法和疏干体积法在划定管理控制水位过程中均考虑研究区未来水资源条件及相应的管控政策，但由于疏干体积法按照县级行政区来划分管理单元，未考虑水文地质条件差异的影响，故在分解到代表性监测井时二者水位变幅差别较大；地下水均衡法全面考虑了当前地下水开发和利用条件、水文地质条件以及地下水管理措施等因素，划定结果与实际更相符。【结论】改进的地下水均衡法划定结果与实际更相符，更适用于平原区浅层地下水管理控制水位的划定。 |

| Abstract: |
| 【Objective】 Predicting change in groundwater table in response to natural and anthropogenic influence is a prerequisite in groundwater resource management. This paper compares several methods commonly used in studying groundwater dynamics based on the shallow groundwater exploration in plain areas in central China. 【Method】The study was based on shallow groundwater resources in Puyang City in Henan province. We analyzed the groundwater dynamics in the region using three methods: water balance method, dewatering-volume method, and time series method. 【Result】 The time series method is applicable only to areas where groundwater development and utilization do not show considerable change with time. In contrast, the water balance method and dewatering volume method are more mechanistic, providing more accurate results as they consider potential changes in groundwater usage and management. As the dewatering volume method divides the studied region into subunits based on administrative regions rather than hydrogeological conditions, it could lead to significant differences when compared to measurements from monitoring boreholes. The water balance method considers factors such as current groundwater development, hydrogeological conditions and groundwater management measures, and it is hence more accurate for analyzing groundwater dynamics.【Conclusion】 Results calculated by the improved groundwater balance method proposed in this paper are consistent with ground-truth data. It is more reliable for evaluating the response of shallow groundwater table to change in management and usages in plain areas. |
