摘要
济南市地下水资源紧缺,合理开发利用地下水资源,对生态环境保护至关重要。本文采用分布式水文模型SWAT对济南市典型流域地下水分布规律进行分析,对地下水资源量进行评价。研究结果显示:2014~2018年,典型流域地下水补给量68.13 mm,地下水补给资源量2.74×10^(8)m^(3)。降水是地下水补给的主要水源,不同时间尺度下,降水与地下水补给量均具有相关性,年尺度下,R2达到0.95。2014~2018年,地下水补给资源量呈增加趋势,其中,特枯年0.40×10^(8)m^(3),枯水年1.44×10^(8)m^(3),平水年4.01×10^(8)m^(3)。受地形与水文地质条件影响,地下水补给量与地下水补给资源量在空间上呈聚合分布。研究结果对于济南市地下水资源可持续开发利用具有指导意义。
Jinan City is in short supply of groundwater resources.Rational development and utilization of groundwater resources is crucial to the protection of the ecological environment.In this paper,the distributed hydrological model SWAT is used to analyze the groundwater distribution,and to evaluate groundwater resources in typical watersheds of Jinan City.The research results show that:from 2014 to 2018,the groundwater recharge was 68.13mm,and the groundwater recharge resources were 2.74×10^(8)m^(3) in a typical watershed.Precipitation is the main source of groundwater recharge.There is a correlation between precipitation and groundwater recharge at different time scales.On the annual scale,the correlation coefficient R2 reaches 0.95.From 2014 to 2018,the groundwater recharge resources showed an increasing trend,of which the extreme drought year was 0.40×10^(8)m^(3),1.44×10^(8)m^(3) in dry years and 4.01×10^(8)m^(3) in normal years.Affected by terrain and hydrogeological conditions,groundwater recharge and groundwater recharge resources are aggregated in space.The research results have guiding significance for the sustainable development and utilization of groundwater resources in Jinan City.
