摘要：
1. A method for determining the size of test sites on the analysis meadow grass species composition, comprising recovering at low river or its tributary visually map or by full scale portion with flood meadow grass, then at this site downstream of the small river or flows to mark a specific field hydrometric least three cross-sections in the transverse direction along each hydrometric alignment mark out at least three test areas on each side of a small river or its tributary, and after the detected patterns p exponent samples of grass, characterized in that to calculate the diversity of species of herbal plants on the site of floodplain meadows release point for future centers of complex test plots, then each center complex test plots hammer pegs and concentrically mounted square frames of different sizes side, the square box set with orientation along the sides and across small bed of the river or its tributary, then within each square was counted frame number of kinds of grass and recorded in tables for each of the size of sample plots in which the rows is a list of all kinds of herbs, and the columns indicates the number of complex test plots, then the amount of species is calculated in rows and columns and trial sites to these amounts are calculated on the total amount of species and the total amount of all complex sample plots, then the statistical simulation reveal rank distributions for the two indicators: the relative occurrence of each species in all test areas and a variety of grass species on each site of a test chastka after1. Способ определения размеров пробных площадок по результатам анализа видового состава луговой травы, включающий выделение на малой реке или ее притоке визуально по карте или натурно участка пойменного луга с травяным покровом, затем на этом участке по течению малой реки или ее притока в характерных местах размечают не менее трех гидрометрических створов в поперечном направлении, вдоль каждого гидрометрического створа размечают не ме
