The Analysis of the Dynamics of Territorial Structures of Natural and Anthropogenic Geoecosystems by the Methods of Virtual Simulation

Abstract

The structure of landscapes morphology of particular territories is characterized by the irregularity and fragmentary nature of landscape structures. The geometrical structure, which is described by some fractal dimensionality, is a generalized common property of different types of natural-territorial geoecosystems. The "supporting framework" of the territory, as its geometric model, was designed on the basis of a geomorphological description of the landscape morphology of a natural-technogenic geoecosystem. The model of the "supporting framework" of the landscape is similar to the real natural-technogenic geoecosystem and preserves its fractal dimensionality, represents the morphology of the landscape structure as well as the influence of zonal factors, geological conditions of landscape formation. The models of the "supporting framework" of the landscape are used as models-simulators of the processes of natural and anthropogenic origin when studying the dynamics of natural-technogenic geoecosystems. The analysis of the dynamics of the "supporting framework" of the natural-technogenic geoecosystem is consigned to the analysis of some virtual structure of a flat rod truss, which is loaded with forces that simulate some anthropogenic effects. This allows to optimize the permissible limits of the impact intensity of the anthropogenic component on the "supporting framework" of the natural-technogenic geoecosystem. The paper suggests a virtual studying of the "supporting framework" of the territory by the method of modeling on the principle of electrical dynamic analogies. Herewith, the currents in the electrical circuit, which simulates the set of structural elements of the "supporting framework" of the natural-technogenic geoecosystem, are analyzed. When being used at a design stage, the suggested methods of analysis allow to optimize the processes of transformation of natural-territorial complexes and ensure the maximum possible level of their ecological safety. The analytical optimization of the alternative variants of transformation of natural territorial complexes allows to reduce the levels of anthropogenic (man-made) impact on them by 15 -20%.
