BNU-SWAT模型应用工具开发

DEVELOPMENT OF BNU-SWAT SYSTEM

北京师范大学数字流域实验室在美国SWAT模型的基础上开发了BNU-SWAT模型应用工具.与原有SWAT模型相比,该工具具有以下特点:1)根据模拟计算结果,快速生成GIS专题图,易于分析水文要素的空间分布规律;2)提供地下水相关参数设置接口,实现了对地下水水位的模拟功能;3)提供子流域水量平衡分析功能;4)提供气候和土地利用变化情景设置功能,丰富了模型的应用能力.该工具在北京市、福建省泉州市、贵州省贵阳市和山西省潞城市等地区得到应用,取得了良好的效果.

BNU-SWAT,developed by Digital Watershed Laboratory,Beijing Normal University based on Soil and Water Assessment Tool（SWAT）,is presented in this paper.Compared with the original SWAT,BNU-SWAT has the following features.1） The fast display function of thematic maps is developed.It will find distinctly characteristics and tendency of time series that maybe difficult to be detected.2） The function of groundwater simulation is realized through groundwater parameter setting provided by the system.3） The water balance analysis module at subbasin levels is also provided.4） Scenarios setting modules for climate and land use changes are included in the system,which greatly enhances the capability of SWAT model.The system has been applied in Beijing,Quanzhou,Guiyang,Lucheng with satisfactory results.
