with alfalfa planted at changwu agri-ecology experimental station as an example
according to the formative mechanism of the pasture yield
the potential productivity of the artificial sown pasture and the livestock carrying capacity have been calculated on the basis of a series of experimental datum. And the effective coefficient of each ecological factors which effect pasture yield is quantified. Then the measures are pointed out for improving the pasture yield and livestock carrying capacity.
