同位素方法在太浦河调水试验中的应用

在2006年3月22日~4月6日开展的太浦河调水试验中,进行了同位素同步监测。根据水量平衡和D1、8O同位素质量守恒原理,运用同位素方法计算了调水期间两省一市的水量分配,分析了黄浦江水源地三条主要支流的来水组成情况。根据D1、8O同位素丰度峰(谷)滞后法,推算了太浦河泄水的输水传播时间,为应对黄浦江水源地突发水污染事件提供了参考。结果表明,D1、8O同位素方法在该研究区域的应用具有较高的精度,该方法在平原河网地区感潮河流中具有其独特的应用途径和其它方法所不可替代的应用价值。

On isotope hydrology method during the experiment of diverting water from Taipu River

From the experiment of diverting water from Taipu River during 22~(nd),March to 6~(th),April in 2006,isotope synchronous monitoring was carried out the same with water quantity and water quality.Based on the water balance and mass conservation of isotopes D and()~(18)O,isotope method is used to explore the following three problems: first,the distribution of water quantity along Taipu River;second,the water component coming from three main water resources of the upper Huangpu River;third,the transmit time of Taipu River drainage to the upper Huangpu River reply the sudden accidents of water contamination.Results indicate that the accuracy is higher.Isotope method has its own unique application in surface water area especially in plain rivernet work.
