Abstract: | Northern Shaanxi is located on the Erdos syncline, a subdivision of North China Shield. The loess landforms are the main landform types, additionally, there are low rocky mountains and hills, valleys and eolian landforms. Changes of techonic bases and of water-heat conditions in the region cause obvious regional differentiations of the landcape. From south to north,accompanying with uprising of the relief and decrease of mean annual temperature and precipitation, the types of landforms, degree of dissection,vegetation cover-degree and intensity of soil and water loesses show clearly latitudinal zonation. |
