This article is devoted to assessing the productivity of grass communities in the Malaya Sosva River floodplain (Reserve "Malaya Sosva"). The three-year studies (1986-1988) at six sample plots (SP) were conducted. The main goal was to evaluate the productivity and its relationship with hydrological and meteorological factors. The method of N.F. Khramtsova was used [1974], which allows to avoiding disturbance of vegetation on the SP, as well as performing statistical data processing. The obtained results reflected the close relationship of productivity with soil moisture, connecting to the position in the relief – aboveground biomass increases to the Malaya Sosva River. At the same time, the increase in biomass has a weak relationship with meteorological factors (temperature and precipitation), despite the weather contrasting seasons. The grass communities show relative stability by significant fluctuations in hydrological and weather conditions in different years. There is an inverse correlation between productivity and biodiversity. A similar trend was observed for the flood plain of the Ob River. But there is a significant range of values in the Ob River floodplain due to the extended flooding.
