this paper adopted hypsometric theory to study the quantitative representation of the evolution stages of Danxia landform. The result indicates that the hypsometric curve is changed from convex to concave with the development of Danxia landform from young to mature
and the concave features are gradually strengthened
while the HI value is getting smaller and smaller
which is consistent with the law of Danxia landform evolution. Based on the comparative study of different sub-zones in the same Danxia landform region
hypsometric curve and index can reflect the multi-stage evolution in the same Danxia landform region. In addition
the comparative study of the same area shows that there is a general scale effect in the evolution phase of Danxia landform
which needs to be fully considered in the calculation of hypsometric curve and index.
