摘要
为探讨SWAT模型在中小流域的适用性,以卧虎山水库流域为例,在3S技术的支持下,制备了SWAT模型所需的DEM、土地利用、土壤及气象等数据库,构建了卧虎山水库流域SWAT分布式水文模型,并以2007-2009年实测数据对模型参数进行率定,以2010-2011年数据进行模型验证。结果表明,逐月径流量模拟值与实测值的Nash效率系数、相关系数均大于0.70,相对误差小于15%。总的来说,SWAT模型可适用于卧虎山水库流域的地表径流模拟,可以在该地区推广应用。
In order to study the applicability of the SWAT model in small and medium-sized basins, the author installs DEM, land u- tilization database, soil database and climate database for the establishment of SWAT model based on 3S, and establishes distributed hydrological model in Wohushan Reservoir watershed. Then, the parameters were calibrated by observed flow from 2007 to 2009 and were validated from 2010-2011. The results show that the correlation coefficient and Nash coefficient of monthly runoff simulation were higher than 0. 70, and the relative error was lower than 15 %. Overall, the SWAT model functions well in the Wohushan reser- voir watershed.
