Abstract
The purpose and objectives are to study the spatial-temporal anisotropy of the geomorphological processes and asymmetry of multi-ordinal forms of relief (by the example of the Russian Far East). The methods of “thorough study of the complex geographical envelope” (comparative-geographical, informational, paleogeographical) as well as other methods worked out by the author were used. The carried-out developments emphasizing the novelty of the study can be demanded in the practice of choice of optimum alternatives of the nature management with respect of minimizing the possible geo-ecologic risks.
Highlights
In the differently expressed long-time manifestation of asymmetry, the spatial-temporal anisotropy of geomorphological processes and relief forms is fixed to the maximum extent
The latitudinal zones of asymmetry are separated by the “symmetry belt” experiencing together with the southern type of asymmetry the greatest changes over the course of the Quaternary period)
The richest and most variable spectrum of the spatial-temporal manifestations of asymmetry of multiple-ordinal forms of relief is characteristic of the Russian Far East
Summary
In the differently expressed long-time manifestation of asymmetry, the spatial-temporal anisotropy of geomorphological processes and relief forms is fixed to the maximum extent. The essential role of asymmetry of low-ordinal erosive forms caused by the anisotropy of geomorphological processes on the slopes of different expositions in the valleys of small rivers is identified (according to the data of numerous authors: A.A. Borzova, 1913; I.S. Shchukin, 1934; S.S. Voskresensky, 1947; E.A. Presnyakov, 1955; Yu.G. Simonov, 1959; G.M. Epstein, 1961; A.M. Korotky et al, 1977).
