摘要

城市地貌决定着城市的布局和发展方向等方面．以咸阳市为例，对DEM数据进行分析，利用ArcGIS软件分析高程、坡度、坡向3个地貌要素．经过分析得出，咸阳市地貌类型包括河漫滩、一级阶地、二级阶地、三级阶地和黄土台塬，从渭河向两侧地势呈阶梯状抬升；咸阳市区绝大部分为平坡地(0°～5°)，占总面积的83.6%；其次是缓坡地(5°～15°)，占总面积的11.8%；其余坡地所占比例甚少．咸阳市区西南、南、东南3面坡向占总面积的60.8%，其中以东南坡向为主，占34.6%；而西北、北、东北3面坡向占总面积的18.9%．咸阳市沿着渭河东西发展，道路交通以及排水系统受阶梯地形影响很大．

Abstract

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.
