The wavy distribution curve of precipitation formed on the longitudinal-arranged underlying rangegorge landforms.At leeside of range, dry valley formed due to fohn effect.
The general formula about the calculation of downslide force and resistance to sliding in the arbitrary unit of landslide is deduced in the digital landform image.
It was estimated that the prospect perspective were weakness in Zhidan area once, since data was narrow, and prospect is difficult for complicated landforms (vale, ridge and replat).
" This allows us to extract age information of specific features or landforms in this area, which can be investigated by the latest NASA Mars Rover when it arrives" .
