EVALUATION OF THE INFLUENCE OF NEOTECTONICS ON FOREST ECOSYSTEMS AND ON THE ORIENTATION OF THE NETWORKS OF SMALL GEOACTIVE ZONES
The research was carried out by methods of spatial and geostructural analysis on the area of 300 km2 with the allocation of geodynamic active zones in the reserve "Vishersky" and in the valley of the Kama river in the forests of Perm. To determine the places that affect the structure of phytocenoses, biolocation was used and small geoactive zones (SGA-zones) with diameters of 1 and 8 m were found, with the laying of five tracks of them at a distance of up to 120 m in the reserve. In the forests of Perm, mapping was more detailed, with 735 pine trees in an array of 2.2 hectares and SGA-zones for five types applied to the plan. It turned out that these zones determine the localization of most large trees and their biogroups, as well as ring formations of fern and Veratrum Lobelia in the sub-Holtz zone. Discovered pair SGA-zones range 8.0 m with the direction of the main lineaments of regional disjunctive tectonics, whereas the orientation of the network of SGA-zones range 1.0 m determines, apparently, the direction of subordinate lineament lesser extent. For the first time it is established that the diameters of small geoactive zones satisfactorily correspond to an infinite number of Fibonacci numbers, except for the zones of the range of 21 m, which are not fixed yet, perhaps due to their weak influence on the biota or other features. It was also found that SGA-zones of two types with diameters of 8.0 m and 1.0 m form networks and their orientation coincides in the reserve "Vishersky", but near Perm the orientation of the sides of the cells of these networks differs by 30-70°. The differences were found for the first time; apparently, they are due to the different direction of the lineaments of the zonal level, which in the reserve is mainly meridional, and near Perm is diagonal.
