Mmethodology of estimation of the complexity of the geomorphological structure of the earth’s surface relief

Abstract

The article highlights the development trend of the morphometric method for studying the geomorphological
structure of the terrestrial relief. The essence of the content and features of various morphometric
approaches to the assessment of the geomorphological complexity and patterns of the structure
of the terrestrial plot are presented. The recommended methodology for assessing the complexity of
the geomorphological structure of the terrain of a terrestrial surface includes a complex characteristic of
complexity, expressed in the form of an analytical model, modified through the basic evaluation mechanisms
and parameters of the formation of the geometry of the terrain of the earth’s surface. The methodological
basis of the recommended method for assessing the characteristics of the variability of the dissection
of morphometric terrain features is the concept of using informative modal and spatial-statistical
values of the first or second differences of georesource values. As is known, the first or second differences
of a trait as a characteristic of its variability are widely distributed and, along with the standard deviation,
remain the main evaluative characteristics expressing the spatial-statistical fluctuation of the distribution of traits as a whole. In this work, the initial parameters of the recommended complex characteristic of
geomorphological complexity are established: the dispersion measure of scattering modal values of the
relief heights, the average unit area of the relief height per unit of allocated height and the total area of
the studied land site. The method we recommend for assessing the geomorphological complexity of the
structure of a terrestrial plot is to assess and determine the complexity of the topography of the studied
site using the developed model of the complex characteristic.
