为深入研究济南岩溶泉域地下水资源变化的现状及未来发展趋势,探索地下水资源可持续管理途径,文章建立了济南泉域地下水稳定流和非稳定流模拟模型,分析了地下水流场及泉水流量变化趋势,并圈划了泉群地下水汇流带。在泉群汇流带内开采地下水直接影响泉流量,而水源地开采通过影响泉群汇流带间接影响泉流量。泉流量呈明显的季节性变化,且与降水量紧密相关:丰水期水位升高,泉流量增加;枯水期水位降低,泉流量减少。保护天然补给量与增加人工补给量是保证泉水长流的重要措施。
In order to further study the current situation and future development trend of groundwater resources in Jinan karst spring area and to explore the ways of sustainable management of groundwater resources, a simulation model of steady flow and unsteady flow of groundwater in Ji’nan spring area is established. The variation of groundwater flow field and spring flow is analyzed Trend, and circle Quanquan groundwater convergence zone. The exploitation of groundwater in the confluence zone of Quanqun directly affects the spring flow, while the exploitation of water source indirectly affects the spring flow by affecting the convergence zone of Quanqun. The spring flow shows obvious seasonal changes and is closely related to precipitation: the water level rises during the wet season and the spring flow increases; the water level decreases during the dry season and the spring flow decreases. Protecting natural recharge and increasing artificial recharge are important measures to ensure the long runoff of spring water.
