Development and Impacts of Eroded Landform on Side Slope of Wuling Tableland
Based on previous research results and field investigations of eroded landform on side slope of the Wuling tableland
in the Eastern Guanzhong Plain of Shaanxi Provinc remote sensing satellite images and other information are applied to analyze the development of eroded gully and loess collapse on the southern and northern edges of the tableland. The development conditions
spatial differences and influence factors for the eroded landform are discussed. Studies show that the river sill(8~30 m high loess cliff) on the southern edge of the tableland is the cave settlement zone
the eroded gully and loess collapse are affected by runoff and the cave zone on the edge with eroded gully presents the development of a small density but large scale on the eastern edge
but vice versa on the western section. On the river sill of the northern margin(30~90 m high loess cliff)
the major development of the western part is characterized by massive loess collapsing
but the eastern part has small amount and long eroded valleys. The eroded landform development on side-slope of the Wuling tableland is mainly affected by geological structure
topographical conditions
new tectonic movement
loess lithology and structure
atmospheric precipitation and irrigation
as well as human activities. It has negative effects on inhabitation security
slope erosion
highland heritage conservation and the development and construction of the New Xi'an-Xianyang Developing District. Academia and relevant government departments should pay attention to the treatment and prevention of geological disasters on side-slope of the Wuling tableland.
