| Abstract: | A study of the grassland population structure, biomass, and quantitative productivity has been conducted. The principle of mathematical deduction and actual measuring consummate the method of grazing grassland vegetation yield and number of species, as well as the mathematical deduction formula, which leads to the attaining of accurate answers, and saves time and effort as well. The present paper consists of three sections, elaborating on beta-binomal, power function, and estimation of biomass. |
