| 摘 要： | 涞源泉泉域是一个全封闭式泉排型岩溶水系统,泉水利用对当地工农业生产发挥了重要作用.通过对涞源岩溶地下水系统特征分析,利用地表水系列资料,采用基流分割法、相关系数法等,计算出泉水量系列资料.由降水补给地下水,再以泉水的形式排泄,在此过程中使水量在时间上滞后,而且水量趋于平稳,泉水量年极值比为7.33,变差系数为0.34,年内分配变化幅度平缓.由降水—入渗—地下径流—泉水排出的过程,水资源经过地下岩溶调节作用,有利于水资源的开发利用,而且对水质也起到净化作用.研究和分析岩溶地下水径流量变化特征,为合理利用泉水资源提供科学依据.

| Abstract: | Laiyuan Spring domain is a fully enclosed karst water system with spring discharge,and the use of spring water plays an important role in local industrial and agricultural productions.According to the analysis of the characteristics of the karst groundwater system in the Laiyuan area,the amount of spring volume was calculated using the base flow separation and correlation coefficient methods based on the surface water data.Results indicated that precipitation recharges groundwater,and then discharges in the... |
