Abstract


Using GIS, take Guanshan basin of Yongdinghe River as an example, based on the remote sensing data of watershed underlying surface, we delineate Guanshan basin into 9 hydrological response units (HRU) through reclassification and spatial overlaying analysis of watershed terrain, land use, soil and vegetation coverage degree, analyze the hydrological characteristics of each hydrological response unit, and the spatial discretization of distributed basin modeling gets realized.

Keywords


GIS, remote sensing data, spatial discretization, hydrological response unit
