针对SWAT模型在湿地水循环模拟过程中存在的不足,以扎龙湿地为例,根据湿地的水文特征,在SWAT模型基础上重新构建了湿地模块来模拟扎龙湿地水文过程,并以1987~1989年月出口径流量对模型进行率定,2005~2006年月出口径流量对模型进行验证。结果表明,改进的模型能较好地模拟扎龙湿地水文过程和湿地水文特征,模拟结果具有较高的可信度。 Aiming at the shortage of SWAT model in the process of wetland water cycle simulation, taking Zhalong wetland as an example, the wetland module was reconstructed on the basis of SWAT model to simulate the hydrological process of Zhalong wetland based on the hydrological characteristics of wetland. From 1987 to 1989 Monthly export runoff rate of the model set, from 2005 to 2006 monthly export runoff to verify the model. The results show that the improved model can better simulate the hydrological process of Zhalong wetland and the hydrological characteristics of wetlands, and the simulation results have higher credibility.
