| 摘 要： | 针对SWAT模型在寒区水文循环模拟过程中存在的不足,对冻土条件下的地表径流模块和升华及土壤蒸发模块进行了改进,并以塔河流域为例,对模型改进前后的径流模拟结果进行了对比。结果表明,在全系列径流模拟中,改进后模型模拟精度有一定程度的提高;在春汛期径流模拟中,改进后模型模拟精度提高较明显,率定期和验证期相对误差绝对值分别下降12.57%、5.67%。对比研究结果证明,改进的SWAT模型在寒区水循环模拟中的适用性得到了进一步提高。 |

| Abstract: | The SWAT model is insufficient in hydrological cycle simulation in cold region. Based on SWAT model, this paper improves the surface runoff module, sublimation and soil evaporation module in frozen soil conditions. Taking Tahe watershed for an example, the results of runoff simulation are compared. The results show that improved SWAT model raises accuracy for runoff simulation; in spring flood season, improved SWAT model increases simulation accuracy obviously; the absolute value of relative error reduces 12.57% (in calibration period) and 5.67% (in validation period), respectively. Therefore, an improved SWAT model has more applicability for hydrological cycle simulation in cold region. |
