| Abstract: | After W. Davis' erosion cycle theory and A. N. Strahler's Method (Area - Altitude IntegrationAnalysis Method) . the concept of erosion integrated value (V/HA) is proposed in this paper. The EIV re-flects the status of immigration of a drainage. The critical EIV, derived from the sand preduction character ina drainage, is the only quantitative indicator to determine it's developing stage. It clearly determined theyouth and maturity stage of the geomorphologic developing stage. |
