On the study of the morphological structure of the relief: an experience in cartometric analysis of the data on the relief ruggedness

Abstract

A cartometric analysis of the maps of the dissection depth and density and regionalization of the Ukraine and Moldova territory according to the erosional risk resulted in a number of indices which describe spatial morphological structure of the regions. Measurements of areas and boundary lengths of elementary units on the first map (that is elementary typological units) were used as a basis of the indices calculation. Methods of the calculation and maps and diagram compilation are described for each index and their sum.
