摘　　要：晋祠泉是我国北方著名的岩溶大泉,汾河河道地表水渗漏是晋祠泉域岩溶水系统的重要补给来源之一,由于岩溶裸露区河流渗漏过程十分复杂,对其渗漏特性的研究及渗漏量的估算始终缺乏详细的数据资料支撑。在梳理前人河道测流资料及渗漏量估算成果的基础上,结合2018年泉域内汾河干流多个断面分段测流试验数据,综合考虑各分段区间汇入量对河道渗漏的影响,分析各河段地表水渗漏情况,重新修正不同河段河道径流量与渗漏率之间的关系方程,推算出泉域内汾河干流河道的多年平均渗漏量。研究表明:汾河水库-扫石段河道多年平均渗漏量为1.478 m^(3)/s;河道分段渗漏量与河道径流量呈非线性关系;在渗漏量估算时,区间汇入量不可忽略。Jinci Spring is a famous karst spring in northern China.The surface water leakage of Fenhe River is one of the important recharge sources of karst water system in Jinci Spring area.Due to the complexity of the river seepage process in karst exposed area,the study of river leakage characteristics and the estimation of the leakage amount are always lack of the detailed data support.Based on the previous runoff observation data and leakage estimation results,combined with the multi-section runoff observation data of Fenhe River in 2018,the relationship equation between river runoff and leakage rate in different river sections was established,and the multi-year average leakage amount of Fenhe River in spring area was calculated.The results showed that:the multi-year average leakage of Fenhe Reservoir-Saoshi section was 1.478m^(3)/s.There was a non-linear relationship between the leakage amount and the river runoff.Besides,the inflow of the section cannot be ignored when the leakage was estimated.
