| 摘 要： | 山东省广饶县地下淡水资源丰富,是本区工农业生产和生活用水的重要水源,长期大量开采地下水引发了地下水降落漏斗、咸水入侵、地面沉降等地质环境问题。通过对广饶县地下水多年监测资料的整理和分析,揭示了本区地下水水位的变化规律,预测了地下水水位的变化趋势。分析表明: 在现状开采条件下,浅层地下水降落漏斗已基本稳定,无加重趋势。考虑地面沉降和咸水入侵的发展趋势,提出深层地下水的约束埋深不应大于80 m,甄庙地区咸水入侵临界水位为10 m,这为当地地下水的合理开采与环境地质问题的防治提供了依据。

| Abstract: | Guangrao County is rich in underground water resources, which is an important source of industrial and agricultural water for production and domestic use. And there are some geological environmental problems such as groundwater depression funnel, saltwater intrusion and land subsidence, due to the long-term large-scale exploitation of groundwater. Through the collection and analysis of the multi-year monitoring data of groundwater level, the authors in this paper have revealed the evolution law of groundwater level and predicted the change trend. The results show that the shallow groundwater depression funnel has been basically stable without aggravating trend under current mining conditions. Considering the developing trend of the land subsidence and saltwater intrusion, the authors have concluded that the restricted depth of deep groundwater is no more than 80 m, and the restricted depth of saltwater intrusion in Shimiao area is 10 m, which has provided the technical basis for the rational exploitation of local groundwater and the prevention of geological environmental problems. |
