Dusaeva G.H., Maksutova N.V. SEASONAL DINAMICA STOCKS OF ABOVEGROUND PHYTOMASS IN GRASSLAND IS PREDOMINANT FORMATIONS ARE-FESCUE-SALESMOBILE COMMUNITY WITH POA TRANSBAICALICA AND SPIRAEA CRENATAThe article presents the results of a study conducted in 2016 on the territory of the “Burtinskaya steppe” Reserve “Orenburg”. Seasonal dinamica reserves of the top phytomass was studied on the example of herb-predominant formations are-fescue-salesmobile (Stipa zalesskii, Festuca valesiaca, Helictotrichon desertorum, Herbae stepposae) soobshestve with Poa transbaicalica and Spiraea crenata. The accumulation and decomposition of vegetable substances are the most important characteristics of the ecosystem. Stock change of aboveground phytomass can be called as natural causes, such as meteorological conditions and anthropogenic impacts. Follow-up of these phenomena on the territory of the protected area allows you to separate these factors. To study the reserves of the top phytomass in the protected steppe, which is considered as the reference ecosystem was the analysis of processes of accumulation and distribution in connection with the variability of weather conditions of vegetation period. These indicators are specific phytocenosis and reflect his adaptation to the environment. The study of seasonal development showed that within the four seasons of the year are allocated Padsasonny or periods that are characterized by the presence of groups of species with similar phenological rhythm of development or, on the contrary, similar processes of dying. In the studied community during the period of the growing season, we were allocated another Padsasonny or periods: rannevesennem, spring, ranelate, summer, late summer and autumn. Key words: seasonal dynamics of stocks of aboveground phytomass, plant communities, vegetation periods.
