Effects of Spatial Resolution of Soil Data on Hydrological Processes Modeling
土壤数据空间分辨率对水文过程模拟的影响

The prediction accuracy of a distributed hydrological model depends on how well the model input spatial data describe the characteristics of the watershed.Especially,in a large scale catchment,could a higher resolution of input data contribute to a more accurate result? As an important component of input data,soil information directly impacts the accuracy of the simulation of hydrologic model.In this study,surveyed soil data with two different spatial resolutions were used as input data for a SWAT model sim...
