摘要:
鄱阳湖区地势平坦,河网交错,无法通过传统水文观测手段得到区间水量,只能采用水量平衡法等间接方法计算得出。本文采用新安江三水源模型,对湖区产汇流规律进行探讨,利用新安江模型作为一个分散性模型的优势,将产流区按陆面和湖面等分成多块,对每块单独进行产汇流计算,模拟每块的出流过程,然后经河网汇流演算,总和后求得整个流域出口断面的流量过程。对新安江模型计算水量的成果进行了分析,结果表明成果总体上是合理的。

Abstract: Poyang Lake area is flat and has interlaced river network, so the water quantity of intervening basin area can not be obtained by traditional hydrological observation methods and only through indirect method, such as water balance method. The Xin’anjiang model with three runoff components was used to discuss the rules of runoff generation and confluence in lake area. Taking the advantage of the Xin’anjiang model as a distributed model, the runoff yielding generation area was divided into many sections on the basis of land and lake surface; By carrying out the calculation of runoff generation and overland flow routing in and obtaining the outflow of each section, and then through the calculation of the river network routing, the flow process of the outlet section of the whole river basin was obtained by accumulation. The water quantity calculated by the Xin’anjiang model was analyzed and the results show that the overall outcome is reasonable.
