Abstract

The article highlights the development trend of the morphometric method for studying the geomorphologicalstructure of the terrestrial relief. The essence of the content and features of various morphometricapproaches to the assessment of the geomorphological complexity and patterns of the structureof the terrestrial plot are presented. The recommended methodology for assessing the complexity ofthe geomorphological structure of the terrain of a terrestrial surface includes a complex characteristic ofcomplexity, expressed in the form of an analytical model, modified through the basic evaluation mechanismsand parameters of the formation of the geometry of the terrain of the earth’s surface. The methodologicalbasis of the recommended method for assessing the characteristics of the variability of the dissectionof morphometric terrain features is the concept of using informative modal and spatial-statisticalvalues of the first or second differences of georesource values. As is known, the first or second differencesof 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 ofgeomorphological complexity are established: the dispersion measure of scattering modal values of therelief heights, the average unit area of the relief height per unit of allocated height and the total area ofthe studied land site. The method we recommend for assessing the geomorphological complexity of thestructure of a terrestrial plot is to assess and determine the complexity of the topography of the studiedsite using the developed model of the complex characteristic.
