摘要
以晋江山美水库集水区为研究区，探讨了SWAT模型在东南沿海径流模拟的适用性，利用该区域的逐日水文气象数据、DEM数据、土壤类型和土地利用等资料建立了日尺度径流模拟SWAT模型，选用2000年--2005年为模型参数的率定期，Ens和R2均达到0．89，2006年--2010年为检验期，Ens=0．87，R2=0．88。结果表明SWAT模型能较好反映区内日径流水文过程，在东南沿海具有良好适应性。在国内日径流模拟研究区中，模拟效率属前列，模拟效率的年际变化表现为丰水年和平水年优于枯水年。
This paper discussed the SWAT model application in daily run off simulation in southeast coastal area. Based on the daily hydrological and meteorological data, DEM, soil and land use data, the SWAT model of shanmei reservoir catchment on the daily time scale was established. The model parameters was calibrated based on the data from 2000 to 2005, the Ens and R2 reached 0. 89. The validation period was selected from 2006 to 2010,and Ens and Rz were 0. 87 and 0. 88 respectively. The result indicates that SWAT model can reflect the daily runoff hydrological process well in the study area, and the model has good adaptability in southeast coastal area. Simulation efficiency belongs to the forefront in the domestic areas of daily runoff simulation. Moreover, the interannual variability of simulation efficiency for high flow year and normal flow year are superior to low flow year.
