摘要
娘子关泉排泄不同岩溶子系统中不同年龄岩溶水的混合水,其中包括当年补给水、平均通过时间为5a的“近年水”和平均通过对间为1.4ka的“老水”。老水的汇水区约8000km^2,太原东山一带岩溶水可能通过远程慢速岩溶子系统补给娘子关泉。老水占泉流量的56%左右。近10ka来,老水已被更新约7次。
The Niangziguan Spring discharges the mixtures of karst waters coming from different karstic subsystems with different ages, including the recharge waters of the same years and the old waters with an average transit time 1.4ka. The catchment area of the old waters covers 8,000 square kilometers or so. Passing through the longrange and low-speed karst subsystem, karst waters from the East Hills of Taiyuan, the capitai of Shanxi province, probably recharge Niangziguan Spring. Having been replaced about 7 times over the past 10ka, the old waters amount to about 56% of the total spring flow.
