Urban landform is one of the basic geographic elements

which determine the formation of the city and the layout direction of development. In this study

Xianyang City was chosen as the study site. DEM data was analyzed and landform maps of elevation

slope and aspect were generated using ArcGIS software. The results indicate that the landform of the city was consisted of river floodplains

T1 terrace

T2 terrace

T3 ter-race and Loess Plateau

elevated from Weihe River. The terrain was dominantly flat (0~~5~)

accounting for 83.6% of the total area

with lands of gentle slope (5-15) accounting for 11.8

and a small portion land with steeper slopes. Approximately 61% of the total area faces southwest

south and southeast

and the southeast faced land accounted for 34.6%. The land facing northwest

north and northeast occupied approxi-mately 18.9% of the total area. The development of urban construction mainly occurred along the Weihe River and the transportation and drainage systems were influenced by the terrace landform.
