【 摘 要 】

The importance of hunting design for the rational use of hunting resources is highlighted. As part of hunting, the role of hunting taxation is defined. Using the example of an exceptionally economically important commercial species, the possibilities of a landscape-interpretation approach for mapping the habitats of game animals are shown. The work makes their inventory on the basis of the landscape-species concept of hunting taxation. According to the habitat conditions, optimal and suboptimal habitats are identified, as well as lands unusual for sable. Criteria for the selection of optimal conditions served as the possibility of providing natural complexes of year-round habitat of sable. The interpretation criteria as suboptimal are the worst habitat conditions of the sable and their use is mainly seasonal. Unusual lands are the areas where the species does not inhabit. In general, the work performed shows the use of ecology (biogeocenology) and modern landscape science in hunting management, including for identifying and displaying natural complexes that are extremely important for homeostasis of the sable population. The region has been identified for the special importance of indigenous Siberian pine (Pinus sibirica du Tour) and the importance of this species for sable is shown. Optimal habitats are characterized by sable population density. The current state of the sable population, taking into account the current commercial use, can be characterized by its homeostasis.
