The aim of research carried out on the territory of the state landscape reserve “Sengiley mountains" was to study disturbance of native forest landscape exactly their basic part-phytocoenosis. The information in which extent the natural landscape of reserve disturbed are extremely important prediction of their development, planning, facilitating to the process of natural regeneration of phytocoenosis, conservation and monitoring of biodiversity on the various levels, regulatory of recreational activities and other actions for the conservation and using of EPNT. The methods of research are traditional used in the practice of forest management. During field works 11 quarters were examined with the definition of ecological disturbance of each sector (all... sectors). Cartographic basis for this work served the plan of forestation, describing one cards of forest valuation of each sector During the research it was found that in the lands capes various phytocoenosis are at the different stages of the recovery of native communities in order of age (under the influence of internal and autologous factors) or reducing (under the influence and allogeneic factors) changes. At the same time these age stages characterize the degree of disturbance of phytocoenosis, which degreases as a result of the succession of landscape state toward the native or close to it dynamic state. The resulting materials allowed to develop a scale of disturbance of forest phytocoenosis and determinate the degree of ecological disturbance of phytocoenosis and agestate of the stand recovery. In the article it is discussed the functional zoning of reserve mage by A.A.Basarov with co-autors (2000). The conclusions: to improve the environmental effectiveness of the reserve is recommended: a) to use the plans of forestation as a cartographic base for planning of the recovery of native landscapes b) to determine the degree of ecological disturbance of phytocoenosis and age state of the recovery of the stand by the suggested scale c) to mark the buffer strips around “the zone of special protection" and “recovery of native landscape zone".

Приводятся данные о природных особенностях и статусе государственного ландшафтного заказника «Сенгилеевские горы», целью организации которого является охрана и восстановление коренных ландшафтов. На основе большого фактического материала, собранного при полевых исследованиях, впервые для ландшафтных заказников обоснованы критерии и разработана шкала экологической нарушенности лесных фитоценозов.
