摘要：

This study introduces a simulation method to identify large-scale land-use parameters that can be used to directly assess how changes in land use affect the generation of runoff. The study examined data during the flood seasons for the Second Songhua River basin, located in the northeast China. The Easy distributed hydrological model was modified to simulate the rainfall-runoff processes of different land-use types. Input data comprised land-use data during a period of minimal human activity and also under subsequent human interference. Time-scale validation and spatial validation both confirmed the suitability of the model for the study area and the feasibility of transferring land-use parameters. Runoff generation per unit area was calculated for each land-use type, and was found to descend in such order: water surface > residential area > unused land > cultivated land > woodland > grassland. © 2014 © 2014 The Hong Kong Instituition of Engineers.
