基于GMS的济南市人工补源影响研究
|
摘要
【目的】探究济南市人工补源对泉水位的影响。【方法】在系统分析泉域水文地质条件的基础上,采用地下水数值模拟软件GMS10.0建立了趵突泉泉域的地下水流数值模型,通过模型对玉符河、历阳湖、兴济河的补源实施效果进行了评估。【结果】玉符河补源水首先沿着炒米店地堑由南向北流,补给西郊地下水,然后再向东、西径流。补源后第177天,补源影响范围基本抵达趵突泉,玉符河补源的最大影响范围为614.32 km~2,对趵突泉、黑虎泉的最大影响水位为0.06 m和0.04 m。历阳湖开始补源后第77天,补源影响范围基本抵达趵突泉,历阳湖补源的最大影响范围为155.52 km~2,对趵突泉、黑虎泉的最大影响水位为0.04 m和0.03 m。兴济河开始补源后第329天,补源影响范围基本抵达趵突泉,兴济河补源的最大影响范围为198.91 km~2,对趵突泉、黑虎泉的最大影响水位为0.02 m和0.01 m。【结论】玉符河、历阳湖、兴济河补源对泉水位起到很好的支撑作用。
【Objective】Study the effect of artificial recharge on the spring water level in Jinan city.【Method】On the base of systematically analyzing the hydrogeological conditions,the numerical model of groundwater flow in Baotu Spring area was established using GMS10.0.And the effects of artificial recharge in Yufu River,Liyang Lake and Xingji River were evaluated.【Result】The results showed that the recharge water in Yufu River recharged the western suburb ground water along the Chaomidian graben from south to north firstly,and then flowed eastward and westward.The maximum influence range of artificial recharge in Yufu River was 614.32 km~2 and the maximum raised water level of Baotu Spring and Heihu Spring were 0.06 m and 0.04 m after 177 days,respectively.The recharge water in Liyang Lake reached the Baotu Spring after 77 days,and the maximum influence range was 155.52 km~2 and the maximum raised water level of Baotu Spring and Hehu Spring were 0.04 m and 0.03 m,respectively.The maximum influence range of artificial recharge in Xingji River was 198.91 km~2 and the maximum raised water level of Baotu Spring and Hehu Spring were 0.02 m and 0.01 m after 329 days,respectively.【Conclusion】The artificial recharge in Yufu River,Liyang Lake and Xingji River played a positive role on the spring water level.
