摘要
为探究基于水量平衡的水文倒推法应用于区间流域径流预报的适用性问题,基于水文倒推法建立了枯季区间径流模拟方程,研究了金沙江中游金江街—攀枝花区间流域2004-2008年的枯季径流情况。结果表明,径流过程模拟效果较好,模拟峰值精度符合要求,与传统区间流域枯季径流预报方法相比,该方法计算简单,预报精度较高。
In order to investigate the applicability of hydrology backward method for applying to runoff prediction inregional basin, which is based on water balance, hydrology backward method is used to establish simulation equation ofdry season regional. And then this paper studies the dry season runoff process from Jinjiangjie to Panzhihua regional basinduring 2004-2008. The results show that the simulation effect of runoff process is good, and the accuracy of peak simula-tion meets the requirements. Compared with the traditional dry season runoff forecasting method in regional basin, theproposed method is easier for calculation and the prediction accuracy is higher.
