为配合太湖流域管理局开展的"太浦河调水改善下游及黄浦江水质试验"研究,利用水量平衡与同位素质量守恒原理构建了河网地区水量分配模型,以解决太湖通过太浦河泄水时河网区(两省一市)的受水量或受水比例问题.模型计算结果表明,利用落潮时的同位素丰度计算的两省一市的受水比例与实际监测成果较为接近.在优化站点、取样频次和取样时间后,该模型具有快捷、简便和经济的特点,可以用来近似估算河网区不同地点的受水量,但其精度有待进一步检验.

In order to cooperate with the Taihu Basin Authority in tests on improving water quality in the downstream reaches of the Huangpu River by diverting water from the Taipu River, a water allocation model of the river network region based on the water balance principle and the isotopic mass conservation was established to solve for the amont of water received (or ratio of received water of two provinces and one municipality) by Taihu Lake from the Taipu River. The calculated results indicate that the ratio of the received water yielded by the proposed method using the stable isotope compositions of the ebb-tide water samples is close to the observed results. The proposed model is convenient, simple and economic after the optimization of isotopic sampling sites, frequencies and time, and it can be used to approximately estimate the received water amount at different sites in the river network region. However, the accuracy should be further validated.
