针对秦淮河流域以水稻土为主的研究区域,探讨在湿润条件下SWAT模型土壤物理属性数据库的建立。将现有的土壤质地资料,通过插值计算,转化成美国制土壤质地。在此基础上率定研究区土壤的相关水文特性,针对研究区水田的管理措施划分其土壤的水文学分组。通过对研究区遥感图像进行反演计算,较为准确地反应特定时段下研究区域的地表反照率,为SWAT模型在大面积研究区域中的应用提供了便捷的可行手段。

In accordance with the study area mainly consists of paddy soil within Qinhuaihe River Basin,the establishment of the database of soil physical attributes for SWAT(soil and water assessment tool) model under moist condition is discussed herein.Through interpolation calculation,the existing data of soil texture is transferred into the soil texture of the U.S.system.On the basis of this,the relevant hydrological characters are rated,and then the hydrologic groups of the soils in the study area are divided based on the management measures for the paddy fields therein.A feasible and convenient method for applying SWAT model to a study area of large area is provided via the inversion calculation made on remote sensing images of the study area and the surface albedo therein under specific period of time with more correct response.
